ZNID 24XX SERIES

This chapter describes the zNID 24xx. It includes the following sections:
Overview, page 13
zNID 24xx series components, page 16
zNID 24xx models and interfaces, page 17

Overview
The zNID 24xx Series (Zhone Network Interface Device) is a family of
indoor, full-featured gateways for residential installations. These next
generation zNIDs support GPON or Active Ethernet termination to meet the
demands of multi-service network deployments to the user.
With either GPON or Active Ethernet uplinks, the 24xx Series zNIDs deliver
data, voice, or video (IPTV) over fiber.
The 24xx series of zNIDs share a common software architecture with the
42xx and 9xxx series of zNIDs, including the same intuitive Web interface
and command line interface. The zNID can also be managed by the Zhone
Network Management System (ZMS) which uses SNMP. Software upgrades
and configuration backups can be handled automatically by the ZMS using
the EZ Touch management feature.
The zNID is a full-featured gateway supporting services such as DHCP
server, rate limiting, filtering, comprehensive logging, and more. The zNID
product line implements a very flexible QoS allowing the service provider to
guarantee that services are being prioritized correctly and the end-user
receives the Quality of Experience that is expected.
All 24xx series Single Family Unit (SFU) ONTs provide the same voice
features found on the 42xx series of outdoor residential SFU ONTs and the
9xxx series of Multiple Dwelling Unit (MDU) ONTs. SIP-PLAR signaling is
supported for connection via Zhone's Voice Gateway to traditional Class 5
TDM switches, while both MGCP and SIP are supported for direct connection
to a VoIP Softswitch. This flexibility allows Zhone's 9xxx, 42xx and 24xx
Series ONTs to work in nearly all Telco networks, with interoperability
support for a broad array of Softswitches.
Zhones GPON ONTs are commonly are used in the 20km range with other
GPON ONTs in the distribution network, though can reach up to 60km
depending on the configuration of the optical distribution network (ODN).

 Web user interface

Web user interface

The zNID 24xx data path architecture is VLAN centric. In other words to pass
traffic VLANs must be defined. The main page for seeing how the zNID is
configured is the Configuration | VLAN | Settings page which shows in the
lower table the VLANs which have been created and the ports which are
members of each VLAN. The type of connection is also displayed in the
lower table. The upper table shows the port defaults. Figure 1 shows the
default state of the zNID 24xx.
To read the Configuration | VLAN | Settings page, see Factory default
VLAN definition on page 87 and Edit Port Defaults on page 145. To
understand more about VLAN options, see VLANS on page 197.
To create bridged, routed, or PPPoE connections as well as configure Voice
interfaces see Deployment scenarios on page 156.

Figure 1: The VLAN settings page shows the VLANs and the ports which belong
to each VLAN

MANAGEMENT

This chapter describes the zNID 24xx. It includes the following sections:
Management interfaces, page 19
Management access control, page 31
System features, page 30
Status and statistics, page 57

Management interfaces
The zNID 24xx products can be fully managed through any of several
methods (CLI, Web, SNMP and OMCI).
The device uses VLAN 7 as the default management VLAN, with DHCP
Client enabled. This allows the ONU to automatically obtain an IP address
when connected to an MXK.

CLI

The zNID 24xx products can be managed using a command line interface.

Web

The zNID 24xx products can also be fully managed through the web (HTTP)
interface. The web pages are very intuitive and they include a context
sensitive help button for additional information. The web interface will be
used for the configuration examples used in this document.

Note: The web pages will vary slightly depending on model.

zNID 24xx Series Configuration Guide 19

Management

SNMP

The zNID 24xx products can also be managed through SNMP. The zNID
24xx family is compatible with any industry standard SNMP agent. However,
Zhone provides a CPE manager feature that makes managing the ONUs even
easier.

OMCI

ONU Management Control Interface (OMCI) provides policy based

configuration and management capabilities for GPON. OMCI management is
intergrated into the OLT command set, so configuration of the ONU with
OMCI is done from the OLT, not directly as with the Web UI or CLI
interfaces. Not all modules in the zNID, such as the wireless interface, can be
configured directly from OMCI, however they may be used with OMCI via
the Virtual Ethernet Interface Point. See OMCI vs. Residential Gateway
management, page 21 for more information.

20 zNID 24xx Series Configuration Guide

 OMCI vs. Residential Gateway management

OMCI vs. Residential Gateway management

For GPON zNIDs, the zNID 24xx may be configured and managed from both
OMCI and from a residential gateway interface (CLI or Web UI). When using
both methods of management it is important to understand how each method
configures traffic flows. OMCI configured data flows are very different from
residential gateway data flows.
The zNID-GPON-24xx models support multiple management interfaces,
however for the purposes of this discussion, the management interfaces fall
into two groups, the OMCI management interface and the RG management
interfaces which includes the Web GUI, CLI and SNMP.
OMCI and RG combine for three types of management modes:
RG only
The RG architecture utilizes and Etherswitch, supporting MAC address
learning and forwarding (ISO layer 2 bridging) as well as routing. This
combination of bridging and routing supported by the zNID provides a
broad base of routing options. See IP configuration options, page 157 for
more information.
The RG interface supports wireless and VoIP options for SIP, SIP-PLAR
and MGCP See Voice, page 134 and Creating voice connections,
page 191 for more information about Voice. Most of this document
explains the RG Web UI interface.
RG only mode is also called RG or RG mode.
OMCI only
Data flows are handled differently for OMCI configured flows than for
the RG flows. For OMCI data flows there is a one to one mapping
between the WAN side GEM port and the LAN side UNI port. All packets
are cut-through the zNID with no MAC address learning or forwarding.
The wireless interface is not supported by OMCI. However to map WiFi
to OMCI there is another type of management which combines RG and
OMCI.
OMCI only mode is also called ONU mode.
Dual mode: OMCI and RG
With dual mode management, the downstream LAN interfaces are
configured via the RG interface, and mapped to the Virtual Ethernet
Interface Point (VEIP). The VEIP is the common interface point between
RG features and OMCI-configured filter rules.
OMCI and RG combined mode always uses the VEIP.

zNID 24xx Series Configuration Guide 21

Management

Comparing RG, OMCI and VEIP by service, traffic forwarding

Another way to understand the three GPON interface types is by service and
traffic forwarding.

RG
With RG interfaces you can configure all service modules on the zNID 24xx.
RG VLANs pass through an integrated Etherswitch and are forwarded based
on Destination MAC to any interface, including the integrated Router. Packets
are classified on ingress and handled by the integrated Ethernet Switch and
CPU routing, voice or WiFi.
RG VLANs use the 5xx GEM exclusively (unless mapped to the VEIP, in
Dual Managed mode, in which case any GEM can be used).
See RG configured flows on page 22 for more information.

OMCI
OMCI configured ONU flows require a 1:1 UNI:GEM mapping.
OMCI configured ONU flows are cut-through flows with no bridging, no
switching, no routing.
WiFi is not supported in OMCI only mode.
Voice can operate as an OMCI-configured function or an RG-configured
function.
RG configured flows and OMCI configured flows can co-exist, but Voice
must be OMCI-configured. Remember the following rule: OMCI always
wins.
See OMCI configured ONU flows on page 24 for more information.

Dual Managed
Dual Managed connections mapped to the VEIP connections may use any
GEM. In this mode, RG VLANs operate as described above, but instead of
using the default 5xx GEM, OMCI is used to configure the GEM and VLAN
filter rule.
See Dual Managed mode using the VEIP on page 27 for more information.

RG configured flows

RG configured flows are flows configured via an RG management interface:

TR-069, Web GUI, Telnet/CLI, or SNMP. This document mainly describes
the Web GUI, so we will not go into much detail about the various
configurations in this section.
For a discussion of the configurations available and example procedures see
Deployment scenarios, page 156 and IP configuration options, page 157.

22 zNID 24xx Series Configuration Guide

 OMCI vs. Residential Gateway management

All services are configured on a per VLAN basis. The RG interfaces can
configure data, video, and voice.
for all RG VLANs, an integrated Etherswitch is included in the data
forwarding path. This enables RG VLANs to support local Bridging and
peer-to-peer communications for LAN client devices such as PCs.
Additionally, a Bridge Table is maintained for all Bridged RG VLANs to
show learned source MACs per VLAN and per Port.
Packets are classified on ingress, then the learning and forwarding switch
determines where to send. See VLANS on page 197 for a discussion of layer 2
forwarding behaviors.

Figure 3: Remote Gateway configured flows

GEM ports in the 5xx - 6xx range are reserved for Residential Gateway traffic
flows.
By default, all RG VLANs map to the 5xx RG GEM. This mapping is not
configurable, and does not require any OMCI provisioning action to create the
5xx GEM on the 24xx unit.
The OLT must not send any OMCI provisioning commands for the 5xx GEM
to the 24xx ONT. The reason is that OMCI always wins. Whatever
provisioning actions that are specified by OMCI commands will occur. If
OMCI attempts to provision the 5xx GEM, the 24xx ONT will create the
specified ONU traffic flows on the 5xx GEM and disruption to RG traffic
flows may occur.

zNID 24xx Series Configuration Guide 23

Management

OMCI configured ONU flows

OMCI configured ONU flows have a one to one mapping between the WAN
side GEM port (GPON Encryption Method port) and the LAN side UNI (User
Network Interface). Other than exception packets which require analysis, such
as IGMP joins and leaves or ARPs, the traffic is generally a cut-through
between the GEM and the UNI.
OMCI configured ONU flows are handled entirely by Classification,
Modification, and Forwarding (CMF) hardware functions. The GPON
interface and each Ethernet LAN port of the 24xx have dedicated CMFs.
Downstream packets that arrive on each GEM are classified based on the
classification rules that have been created by OMCI provisioning actions.
Packets that match a Classification Rule are Modified as specified by that rule
and Forwarded to the egress port specified by that rule. Packets that are not
classified are dropped/blocked. Exception packets that require CPU analysis
(like the IGMP joins and leaves or ARPs) are classified on ingress and
forwarded to the CPU for action. This ONU forwarding architecture is
illustrated in the diagram below.

Figure 4: OMCI configured flows

You cannot map two UNIs to the same GEM when configuring ONU flows. If
three Ethernet Ports must be configured as members of the same VLAN for
High Speed Internet Access Service, three GEMs are required. The same

24 zNID 24xx Series Configuration Guide

 OMCI vs. Residential Gateway management

VLAN is configured on all three GEMs. When configured this way a PC

connected on eth 1 will NOT be able to communicate directly with a PC
connected to eth 2 or eth 3. All packets are forwarded upstream in a secure
manner, and no locally switched port-to-port communication is supported.
All communication between a PC on eth1 and a PC on eth 2 will go upstream
to the OLT and back down again.

OMCI unique features

There are some features which OMCI provides which are not provided
through the RG:
VLAN Translation (changing the VLAN tag)
VLAN Promotion (adding an outer tag)
VLAN Translation & Promotion (changing the inner tag and adding an
outer tag)
Open Trunk (provisioning a cut-through path from an Ethernet Port to a
GEM Port that will pass all traffic through, unmodified, regardless of
VLAN ID). This open trunk is a useful feature for business applications
where a large number of VLANs must be supported.

OMCI configured video

The IP TV application is fully supported in pure ONU mode. The 4095 GEM
is used for all downstream multicast traffic, and the same 1:1 mapping of
UNIs to GEMs is required for handling of uni-cast traffic.
VLAN Translation is supported for the IP TV application, as long as all
Ethernet Ports are members of the same original VLAN. It is not possible to
translate a single downstream multicast video packet to VLAN A for sending
out eth 1, while simultaneously translating the same packet to VLAN B for
sending out eth 2

OMCI configured voice

The SIP Voice application is fully supported in pure ONU mode.
OMCI-configured SIP voice must be mapped to a dedicated GEM. SIP-PLAR
and MGCP voice are not supported in ONU mode.
Voice is unique because it is an ISO layer 3 application that can be fully
provisioned via OMCI and handled as an ONU function, or it can be fully
provisioned via Telnet/CLI, Web GUI, SNMP or TR-069 and handled as an
RG function. In either case, Voice actually operates as an RG function. OMCI
is used to configure the exact same database parameters for voice that are
provisioned via any of the RG configuration interfaces (e.g. Web GUI).
The only difference between ONU Voice and RG Voice is the Bound Interface
that is assigned. When Voice is OMCI-configured, the Bound Interface is a
brg interface created via OMCI. When Voice is RG-configured, the Bound
Interface is an IP Interface created via the Web GUI or TR-069.

zNID 24xx Series Configuration Guide 25

Management

This display is useful for troubleshooting purposes, because you can easily
see how voice is configured using the Web GUI, TR-069, or Telnet/CLI
interface, even when OMCI actually configured it.

Statistics in UNI mode

There are not as many packet-level statistics available for ONU flows since
they are ISO layer 2 cut-through flows as illustrated in OMCI configured
flows, page 24. However there are several useful debug tools.
There is an IGMP Table for OMCI-configured flows, accessible via
Telnet/CLI or Web GUI
Voice Packet Log, Audit Log, and Line Status. Accessible via Telnet/CLI
or Web GUI
Ethernet Port Statistics are provided. Accessible via OMCI, Telnet/CLI or
Web GUI
GPON physical layer statics are provided. Accessible via OMCI, Telnet/
CLI or Web GUI
There is no Bridge Table to show learned MACs for any OMCI configured
flows.

Reserved GEM ports

When using any configuration mode:
GEM ports in the 0xx, 1xx and 2xx range are not supported
The first usable GEM ports for the 24xx ONTs are in the 3xx - 4xx range.
GEM ports in the 5xx - 6xx range are reserved for Residential Gateway
traffic flows
The 501 - 628 GEM range is reserved for Residential Gateway VLANs
configured via the TR-069 or Web GUI interface. The 2426 uses (501 +
ONU ID) as its RG GEM for ONU IDs from 0 to 127.

 OMCI vs. Residential Gateway management

Dual Managed mode using the VEIP

In Dual Managed mode a virtual UNI is the glue between the RG interfaces
and OMCI. The virtual UNI is a Virtual Ethernet Interface Point (VEIP) as
described in G.984.4 Amendment 2 and G.Impl.984.4).
The VEIP allows the features such as Voice and WiFi which cannot be
implemented directly by OMCI, to be configured via RG interfaces. The
uplink is then set to O to designate an OMCI interface. This mechanism ties
the uplink to the virtual UNI.

Figure 5: RG and OMCI in Dual Managed mode, features via VEIP are matched
by VLAN Identifier

When the eth0 interface of an RG VLAN is configured as an OMCI member,

it will be automatically mapped to the VEIP. Conversely, when eth0 is
configured as a tagged or untagged member of the VLAN, it is automatically
mapped to the default 5xx RG GEM.
Up to 24 RG VLANs are supported, and all 24 of them could be mapped to
the VEIP. Each RG VLAN must have a unique VLAN ID. However, VLAN
translation rules may be configured via OMCI to map multiple different RG
VLANs into the same Network-side VLAN (Not configured on the zNID, but
on the OLT).
VEIP Mapping is supported by the following VLAN types: Bridged-CPU,
BRouted, Routed, PPPoE-Bridged, PPPoE-Routed.
All IP attributes of an RG VLAN remain under RG configuration control.
OMCI is NOT used for provisioning of IP Addresses, DNS Addresses, Subnet
Masks, or other IP attributes

zNID 24xx Series Configuration Guide 27

Management

Figure 6: In Dual Managed mode, the VEIP provides access to the other
modules including the wireless interface

VLAN ID is used to automatically bind the RG VLAN and the OMCI Filter
together.

Note: If there are no OMCI Filter Rules provisioned on the VEIP

with a matching Original VLAN ID, then the RG VLAN will not
have a connection into the network.

The VEIP provides mapping of RG VLANs to one or more additional GEMs,

beyond the default 5xx RG GEM. This mapping enables upstream traffic
prioritization via GPON Traffic Profile (GTP) parameters on a per-VLAN
basis. It also provides VLAN translation and promotion features that are not
available for RG VLANs mapped to the default 5xx GEM.

Logging in with CLI

Logging in on the Ethernet ports

The zNID 24xx can be managed from the Ethernet ports.

The ONU has a default IP address of 192.168.1.1 on the Ethernet port.
The user can connect a standard PC to the Ethernet port (eth1) and
configure the ONU using a standard web browser or telnet session. The
PC will need to have an IP address on the same subnet. Typically,
192.168.1.100 is used. Of course, if you change the IP address of the
ONU, you will lose connectivity. You would then need to reconfigure
your PC to be on the same subnet.
The default login is admin and the default password is zhone

Note: For security reasons the password should be changed from the
default password. To change the password see User names and

Default interface

When the ONU must send an internally generated packet (e.g., from SNMP
trap, SNTP, etc.) to an IP address that is not defined in the route table, the
selected default interface's IP address will be used as the source address.
This device has many internal applications such as SNMP, DHCP, DNS,
PING. If one of these applications sends a packet to an IP address which is not
defined in the route table and the application has not been directed to use a
particular interface to transmit the packet then the default interface's IP
address will be used as the source address and routing will be resolved based
on that source IP address.

DNS Proxy Server

When DNS Proxy is selected as the DNS Relay Source on any LAN-side
interface, client devices will send all DNS requests to this Router LAN side IP
Address.
The router checks the Local Host Table for any pre-configured Domain Name
lookups, and if a matching entry is found, responds with the corresponding IP
Address.
When there are no matching entries in the Local Host Table, the router
initiates a Proxy DNS Request using its System DNS Client, then generates a
corresponding DNS response to the LAN-side client with the corresponding
IP Address learned via the Proxy Request.

Figure 14: Displaying the DNS Proxy Server (default shown)

The Host Names of locally attached devices are dynamically learned and
automatically populated in the DNS Proxy Table. Domain Names must be
statically configured. The entire Domain Name must be configured (e.g.
discovery.microsoft.iptv.com) along with the IP Address that should be
returned to the local clients to send a DNS Request for that Domain Name.

Internet time

The System|Internet Time page is used to configure the time of day on the
ONU. The time is retrieved from one of the SNTP servers configured on the
page. The Time Zone is used to set the time to local time. Note that the ONU
does not automatically compensate for Day Light Saving Time.
DHCP Option 42 is supported. If a DHCP offer uses Option 42 to specify an
SNTP server and time zone offset, it will automatically configure the SNTP
attributes on this screen.
The zNID 24xx maintains the time of day for applications such as Syslog. The
time is acquired from one of five specified time servers. If no time server can
be found, the system will default to January, 1. The system allows for up to
five time servers to be configured. If the first server is unreachable, the ONU
will try the next server. If that is not available, it will try the next one, and so
on. The configuration of the time client is shown below.

Software

The Software screens provide options to restore software from the alternate
bank or to use a version of software saved elsewhere.

Restore software
The ONU stores two sets of software. One set, the Current Software Version
or active software, is the software set which is currently running the ONU.
The other set is the Alternate Software Version or standby software, and is
stored in the ONU's alternate (non-running) bank. Clicking Reload will cause
the alternate software to run the ONU after rebooting it, thus it becomes the
current software. The previously current software will then become the
alternate software. After the ONU reboots the system will update its display
of current and alternate Software versions automatically.The configuration
remains unchanged. In other words you do not need to reconfigure the ONU
after completing the restore procedure.
Clicking Reload software will cause the unit to reboot as it switches to the
newly active software. This will happen immediately after clicking no
extra warning message is provided.
Note that when restoring an older version there can be issues with the older
code running with a newer configuration data base. The configuration
database stores the configuration of the interfaces (with all the services, such
as tagging and rate limiting, as well as other configuration information). In
some cases, the ONU will have to reset to factory defaults, and then the ONU
will need to be manually re-configured.

Ethernet port

The ONU has a default IP address of 192.168.1.1 on the LAN Ethernet ports.
The user can connect a standard PC to the LAN ports (eth1-eth4) and
configure the ONU using a standard web browser. The PC will need to have
an IP address on the same subnet. Typically, 192.168.1.100 is used. Of course,
if you change the IP address of the ONU, you will lose connectivity. You
would then need to reconfigure your PC to be on the same subnet.

Lists
There are three options for defining whether packets/frames will be allowed
in on an interface disabled, black list and white list. An interface may only
have one of the three listing options:
Black list defines a set of source IP addresses/MAC addresses which will
not be allowed. All other packets will be allowed.
White list defines a set of source IP addresses/MAC addresses which will
be allowed. All other packets will be blocked.
Disabled allows all packets/frames.

When DMZ is chosen it is the only rule allowed on
that interface. A DMZ rule is effectively the same
as a Range rule with all ports included.
Range
Range rules are more secure than setting a DMZ
rule, because Range rules allow specific ports or
groups of ports to be opened up. Range indicates
that any traffic on those ports will be sent to the
private IP address.
Remap
Remap indicates that any traffic on those ports will
be sent to the private IP address at the private port.

Port Start Lowest value port number for the range.

Port End Highest value port number for the range. This can be
equal to Port Start if there is only one port.

Protocol TCP, UDP or Both indicate which protocols to monitor

for the port numbers.

NAT Interface The Interface to monitor for this rule.

Private IP Address The IP address to which to send the traffic.

Port The Port address to which to send the traffic.

Interfaces

The Zhone zNIDs support a variety of interface types:

Bridged on page 100
Routed on page 101
Brouted on page 102
PPPoE on page 103
Ethernet on page 104
GPON on page 106
Rate limiting is also available for the WAN and LAN Ethernet interfaces. See
Rate Limits on page 107

Bridged
Bridges are ISO layer two functions which connect network segments and
direct traffic based on Ethernet Media Access Control (MAC) addresses.
MAC addresses are a unique address per physical device. Routers are layer
three devices which use IP Addresses to direct packets.
Bridges direct packets based on address information in the packets as well as
information learned from the processing and directing of other packets.
The Interfaces | Bridged page displays the bridged interfaces which have
been defined and the IP address assigned to that interface.
To create bridge interfaces see Creating bridge connections, page 163.

Figure 72: The Configuration | Bridges page, shows existing bridges by VLAN.

To edit a bridge, enter a check in the bridged interface in the select row at the
top of the table, then click Edit Selected Interface.
The table displays Bridged Interfaces along with any IP Addresses that have
been assigned to them for the purposes of enabling management access or
supporting SIP, SIP-PLAR or MGCP clients. The naming convention for
Bridged Interfaces is brvlan followed by the VLAN ID. Bridged Interfaces
are automatically sorted and displayed in ascending VLAN ID order.

Routed
The Internet Protocol (IP) is a network-layer (Layer 3) protocol that contains
addressing information and some control information that enables packets to
be routed. IP is documented in RFC 791 and is the primary network-layer
protocol in the Internet protocol suite.
The Interfaces | Routed page displays the routed interfaces which have been
defined and the IP address assigned to that interface.
To create routed interfaces see Creating routed connections, page 166

Brouted
Brouted VLANs have two IP interfaces one for the Routed uplink interface
and a second for the Bridged LAN-side interface. A Brouted VLAN may have
multiple LAN ports as members, and all ports will use the same IP subnet. So
Brouted means that the LAN side is like a bridge, but has a routed interface
for the WAN side.

PPPoE
The Point-to-Point Protocol over Ethernet (PPPoE) encapsulates PPP frames
inside Ethernet frames to create a PPPoE tunnel between hosts connected to
the ZNID and other devices out in the cloud. While Ethernet is packet-based
(so no direct connection is opened), PPP is a direct connection where one
device directly connects to another using the protocol. PPPoE is a virtual
connection (usually called tunnel) between two devices.
On the Configuration | Interfaces | PPPoE page you can add a PPPoE on a
port by VLAN, either as PPPoE Routed or PPPoE Bridged.
To create PPPoE tunnels see Creating PPPoE tunnels, page 179

Security
The main items for wireless security are authentication and encryption.
Authentication methods which are secure allow the clients (also called
stations or STA) you want onto the network, while keeping others off of the
network. Encryption is used, both in some of the authentication methods and
in the regular transmission of data once the client has successfully completed
the authentication process.

WPA
WPA (WiFi Protected Access) is usually used for the larger Enterprise
environment, it uses a RADIUS server and TKIP (Temporal Key Integrity
Protocol) encryption (instead of WEP encryption which is disabled).
TKIP+AES uses 128-bit dynamic session keys (per user, per session, and per
packet keys). Dynamically creating a new key for each packet prevents
collisions.
AES (Advanced Encryption Standard) is stronger than TKIP. However, the
options provided by the zNID 24xx are TKIP+AES and AES. AES is a later
addition to WPA.
Network re-authorization interval is the time in which another key needs to be
dynamically issued.

WPA-PSK
WPA-PSK (WiFi Protected Access Pre-Shared Key) is basically WPA for
home and small office/home office (SOHO) environments. WPA-PSK uses
the same strong TKIP+AES encryption which is used for WPA, per-packet
key construction, and key management that WPA provides in the enterprise
environment. However unlike WPA which uses a RADIUS server, WPA-PSK
uses a password (WPA/WAPI passphrase) which is entered manually. A group
re-key interval time is also required.

Edit Port Defaults

The VLAN Settings | Edit Port Defaults screen provides the means to define
the VLAN ID and set 802.1p priorities for packets from each Ethernet port.
This screen also sets which port is to be used as the WAN uplink.
The most common scenario is for a PC based subnet on a downstream port.
The port receives the incoming untagged packet on the port and inserts the
Port VLAN ID tag.
When the PVID is set to a specific VLAN it is to insert a VLAN tag for
packets incoming on a downstream interface or directing (and stripping tags)
to egress on a downstream interface. See VLANS on page 197 for more
information and examples.

 Deployment scenarios

IP configuration options

The different bridge types which the zNID 24xx supports provides present
different options for assigning IP addresses.
Bridged
For bridged VLANs, an IP Address can be assigned if the zNID will be a
host in a particular IP subnet.
IP addresses for LAN-side client devices can be statically assigned or
assigned by an upstream DHCP server.
Any number of Ethernet ports or WiFi SSIDs can be members of the
Bridged VLAN
All clients in a bridged VLAN will be in the same IP subnet, and the
zNID 24xx will enable direct local peer-to-peer communications
between all clients unless the Secure Forwarding option has been
enabled.
If Secure Forwarding is enabled, all broadcast traffic is forwarded
upstream and not flooded out the other local ports in the VLAN. This
prevents local peer-to-peer communications, and is equivalent to the
ONU operating mode
Bridged with CPU or CPU-Bridged must be selected for using
bridged VLANs in Dual Managed mode with VEIP

Figure 117: For bridged connections all the interfaces are in the same subnet

See Creating bridge connections, page 163 for the procedures for creating
bridged connections.

zNID 24xx Series Configuration Guide 157

Configuration

Routed
For Routed VLANs, an IP Address will be assigned per physical port that
is assigned to the VLAN. The minimum configuration will have the
uplink interface and at least one LAN-side interface. When there are
multiple LAN ports in the same Routed VLAN, each one must be
assigned its own IP subnet.
In the illustration below, a NAT Routed VLAN has been configured
that contains three LAN ports and one SSID. A total of six IP
addresses are assigned to the 2426 for this configuration. A WAN IP
address is assigned to the uplink, and four LAN-side IP addresses
must be assigned, each in a separate subnet, plus an IP subnet for the
WiFi interface.
All Wi-Fi connected client devices will be in the same subnet. An RG
configuration item called Isolate Clients in the Wireless / Basic
menu determines if these devices will be able to communicate locally
with each other, or if all traffic will be forwarded upstream. When
Isolate Clients is enabled, all traffic is forwarded upstream, blocking
local peer-to-peer communications.
The example below shows a Routed VLAN with NAT. When NAT is
enabled, the Router performs Network Address Translation, mapping
each LAN side IP address and source port to a unique protocol port
used with the WAN IP Address for communications across the
network.

Figure 118: For routed connections each interface is in its own subnet

See Creating routed connections, page 166 for the procedures for creating
routed connections.

158 zNID 24xx Series Configuration Guide

 Deployment scenarios

Brouted
For Brouted VLANs, there are only two IP interfaces - one for the Routed
uplink interface and a second for the Bridged LAN-side interface. A
Brouted VLAN may have multiple LAN ports as members, and all ports
will use the same IP subnet. So Brouted means that the LAN side is like a
bridge, but has a routed interface for the WAN side.
Brouted VLANs enable local peer-to-peer communications between
all client devices, just like Bridged VLANs do. All clients will have
IP Addresses in the same subnet.
A DHCP Server may be configured in the zNID 24xx to
automatically assign local IP addresses in the assigned subnet.
NAT is typically enabled on a Brouted VLAN, using private IP
Addresses locally and a single public IP address on the uplink
interface

Figure 119: For brouted all LAN side interfaces are in one subnet. The uplink is
in another subnet

See Creating brouted connections, page 172 for the procedures for
creating brouted connections.

zNID 24xx Series Configuration Guide 159

Configuration

PPPoE Bridged or Routed

PPPoE bridged or routed connections are very similar to bridged or routed
connections, only that the uplink interface is a PPPoE client that
establishes a PPPoE tunnel to an upstream BRAS
PPPoE/Bridged VLANs are similar to Brouted VLANs, but the
uplink interface is a PPPoE client that establishes a PPPoE tunnel to
an upstream BRAS. On the LAN side of a PPPoE/Bridged VLAN, all
ports will be members of the same IP Subnet.
PPPoE/Routed VLANs are similar to Routed VLANs, but the uplink
interface is a PPPoE client that establishes a PPPoE tunnel to an
upstream BRAS. On the LAN side of a PPPoE/Routed VLAN, each
LAN port will require its own IP subnet.

Figure 120: For PPPoE bridged the LAN side interfaces are all in the same
subnet. The WAN side is in its own subnet and a PPPoE tunnel is created to an

Creating data connections

All connections, including voice and video, are based on the VLAN and all
follow a general procedure:
1 Create VLAN
This first step is the same for all data connections, except for choosing
which connection type. You name the connection and give it a VLAN ID
as well as defining the connection type.
For voice configurations you select Bridged as the connection type and
bind the POTS interface to the VLAN later in the process.
2 Select ports and set port defaults
This step is also the same for all connection types.
For wireless you would select the wireless interface as one of the ports,
then later configure the wireless.
For OMCI & RG combined VEIP connections select O for the uplink
port member.
3 Adjust WAN settings (Routed, Brouted and PPPoE connections)
This step configures the upstream interface.
For routed connections it defines the zNID devices addressing and
whether NAT (Network Address Translation) or DHCP Relay is used for
the client devices on the LAN side.
For video connections you would enable IGMP snooping in this step.
For PPPoE connections this step has a PPPoE address mode used for
defining the IP address for the zNID side of the PPPoE tunnel.
4 Adjust LAN settings (Routed, Brouted and PPPoE connections)
This step configure the downstream interface
For routed connections it defines whether the zNID is acting as a DHCP
server for the client devices and creating a subnet.
For PPPoE connections Network Address Translation is required.
5 Configure wireless (Wireless connections only)
Set port membership, authentication and encryption features as well as
other wireless options.
6 Select voice connection (Voice connections only)
For voice connections you select which of the configured VLANs to
which to bind the POTS interface.

162 zNID 24xx Series Configuration Guide

 Deployment scenarios

Creating bridge connections

In Bridged mode, the zNID 24xx operates as a standard learning bridge. The
source addresses in received packet headers are examined to locate unknown
devices. Until the location of the destination is known, the packets are flooded
to all ports that are members of the VLAN. Once a device has been located, its
location is recorded in a table where the MAC address is stored so as to
preclude the need for further flooding.
In addition, there is a secure forwarding mode. When this mode is enabled,
packets are not flooded to all ports. Instead, all packets are forwarded to the
port that is designated as the uplink port. In this mode, users are prevented
from directly communicating with each other.

Note: Bridged connections for use with VEIP must use the
CPU-Bridged type. See Creating Dual Managed connections on
page 194 for an example creating

a CPU-Bridged type for VEIP.

VLANs can be configured as Routed. With this connection type, packets are
forwarded based on the destination IP address. Explicit routes can be
configured or the system can use the default route, which is the next hop
gateway for the VLAN. A total of 32 routes can be defined.
When in the Routed mode, additional features are enabled such as filtering
(See MAC filter on page 126), and the DHCP server function (See DHCP
server on page 209).

To create a routed connection

1 Create VLAN
This first step is the same for all data connections, except for choosing
which connection type. You name the connection and give it a VLAN ID
as well as defining the connection type.

Creating PPPoE tunnels

PPPoE is defined for the uplink port of a VLAN. In this mode, the zNID
24xx will establish a PPPoE session with a server on behalf of the client
connected to the configured port. Each VLAN can have 1 PPPoE session.
The configuration of the PPPoE session requires only a few parameters:
user name
password
authentication method
When in the PPPoE mode, the uplink port will always perform the NAT
function. This means that the LAN portion will also have the DHCP server
enabled. Depending on how the LAN ports need to be configured, the PPPoE
connection will be defined to be either Bridged or Routed.
The zNID 24xx supports PAP, CHAP or MS CHAP. The zNID 24xx can be
set to auto in which case it will use what ever method the server uses.
PPPoE Bridged Mode
In PPPoE Bridged Mode mode, a single DHCP server will provide
addresses for the devices connected to any of the LAN ports. All ports
will be members of the same IP subnet. They are also all members of the
same VLAN.
PPPoE Routed Mode
In PPPoE Routed Mode mode, there is a DHCP server for each LAN port.
Each port is on a different IP subnet. This method should be used when
the ports are connected to different customers, such as different
apartments that are served from a single zNID 24xx.

 Advanced features

Advanced features

VLANS
The zNID 24xxs support VLAN-based services. This section describes the
types of VLANs that are supported on this device. When configured for
normal single-tagged mode, all ports are members of a VLAN. They can be
untagged or tagged members. Alternatively, ports can be double tagged
members of an S-VLAN.
Ethernet frames that are tagged have a VLAN ID and priority as part of the
Ethernet frame. In this product that is called the C tag or the Customer tag.
This family of products also supports the double tagging feature. The outer
tag is called the S-Tag or the Service Provider tag. This double tag
capability is an advanced feature that allows traffic from multiple clients to be
sent through the network in a common VLAN.
Once the S-Tag mode has been selected from the VLAN Mode page, traffic
leaving the port designated as the S-Tag port, will have the outer S-tag added
to the frame.
The S-Tag mode only works with ports that been defined as TLS members for
the S-LAN, where all tagged traffic on a port is accepted without having to
configure each individual VLAN. When this traffic leaves the system, it will
have the outer S-tag applied to the packets.

All ports untagged

In some configurations the Ethernet ports appear as untagged ports. The
traffic in and out of the ONU will be standard Ethernet frames. However,
internally, the Ethernet frames are VLAN tagged (C-1). This allows the ONU
to prioritize and forward traffic appropriately. The figure below shows the
traffic flow for ports that are untagged.

Figure 155: All ports untagged

This configuration is valid only when all ports are members of the same
VLAN. Otherwise, there is no way to separate traffic. This configuration
would not typically be used when the zNID 24xx is connected to an MXK.
The MXK expects the traffic to be tagged, as described in the next section.

zNID 24xx Series Configuration Guide 197

Configuration

Tagged uplink port untagged LAN ports

The diagram below shows an example of a VLAN tag (C-2) being added to
the Ethernet frame received on the LAN port. In this case the VLAN tag
remains on the frame as it is sent to the network, on the port that has been
designated as the Uplink port. Typically, this is the fiber port. Traffic that is
received from the network is expected to have the C-2 VLAN tag. This tag
will be removed before the Ethernet frame is sent to the LAN port.

Figure 156: Tagged uplink, untagged LAN ports

This is the most common configuration of the zNID 24xx. The MXK expects
tagged traffic on the uplink, while most PCs and set top boxes only use
untagged traffic.
The VLAN configuration web page shows an example of the uplink port
being tagged and the LAN ports being untagged. This is the standard
configuration when connected to an MXK.
If a tagged frame is received on the LAN port, it will be forwarded upstream
unmodified. However, in the downstream direction the VLAN tag will be
removed before sending the frame out the LAN port. This could lead to
undesirable results, since the device sending tagged frames probably expects
to receive tagged frames.

designated as the Uplink port. Traffic that is received from the network is
expected to have the C-3 VLAN tag. That traffic is prioritized and forwarded
based on that VLAN tag. In this case the LAN Ethernet port is tagged,
therefore the C-3 VLAN tag is not stripped from the frame before being sent
to the LAN port as described in the previous example. In this case, the VLAN
tag is preserved.

Figure 158: Tagged uplink and tagged LAN ports

Each Ethernet port can be a member of a different VLAN. The ports can be
tagged or untagged. For this example both Ethernet ports are tagged. The web
page below shows the configuration for a zNID 24xx that is configured for
tagged Ethernet ports and tagged uplink port.
In this mode, if an untagged frame is received on the LAN port, a VLAN tag
will be added as defined by the PVID and the frame will be forwarded
upstream. In the downstream direction, the tagged frame will be passed to the
LAN port without any modifications. This could lead to undesirable results
since the device that sent untagged frames probably expects to receive
untagged frames.

S-Tagged
S-Tag or QinQ is a method of adding a second VLAN tag to an Ethernet
frame. This can be useful for Service providers that have multiple clients on
the same ONU, or for business applications in which the client has their
network segmented with multiple private VLANs that may conflict with
VLANs in use by other customers of the same service provider. The S-Tag
concept allows the service provider to take tagged traffic from a customer
network and transport that traffic though through the network on a single
VLAN without the traffic from one client interfering with the traffic from
another client. The client ports are unaware of the double tag, since it is
stripped before the Ethernet frame is sent to the LAN port.
The outer S-tag is identified by a unique Tag Protocol Identifier (TPID).
Typical values for the TPID are 88A8, 8100, 9100, 9200, or 9300. The default

200 zNID 24xx Series Configuration Guide

value is 8100. This family of products allows that field to be specified by the
user.

Figure 159: S-Tagged on uplink, tagged LAN

On the web interface, the S-tag feature is defined on the VLAN mode page as
shown below. Once enabled, all VLAN traffic being sent upstream will have
the outer S-tag applied to the packet.

Figure 160: Stag is set from the VLAN Service Mode dropdown

TLS mode

Once the ONU has been set for S-tag mode, individual ports can be
configured for TLS (Transparent LAN Services) mode, where all the tagged
traffic received on a TLS port is tagged with an outer S-Tag and forward
upstream. The web page below shows an example of a configuration that has
tagged traffic on both Ethernet ports, and the upstream traffic has an
additional S-tag on the packet. In this example, the traffic on each Ethernet
port could be from different service providers. The service providers could be
using the same VLAN IDs, but the traffic would remain segregated since they
have unique S-tag IDs.
Based on the figure below, in this example, port 1 is set to be in TLS mode. In
that mode, all of the data received on port 1 will have an outer tag of
101added each packet. Data received on the uplink port is expected to have an
outer S-tag of 101, which will be stripped on input.

NAT and DHCP

In this example the ONU will have all ports as untagged. The ONU will
provide the IP addresses to the connected devices through DHCP. Note the
each port has its own DHCP server. The addresses given out on each port
must be in a different subnet. In this example, each port is set to give out 10 IP
addresses. The ONU will perform NAT on the uplink interface to translate the
public IP address to one of the private addresses.
With this configuration, the subscriber should be able to connect a PC to the
Ethernet port, obtain an address and be ready to surf the Internet.

To setup NAT and DHCP

1 Define a routed VLAN

Configuration

2 Define which ports are members of the VLAN

3 Set the PVID

Since this example is using untagged ports, it is critical to set the PVID to
data VLAN. Otherwise all incoming packets will be dropped.

4 Enable NAT on the uplink port

Enable the NAT function, and set the DNS addresses. In this case we are
using static addresses.

DHCP server

Dynamic Host Control Protocol (DHCP) is the means for dynamically

assigning IP addresses. Basically, a DHCP server has a pool of IP addresses
that can be assigned to DHCP clients. A DHCP client maintains its MAC
address, but may have a different IP address each time it connects to the
network. DHCP simplifies network administration since the DHCP server
software tracks the used and unused IP addresses.
The zNID 24xx can act as a local DHCP server for devices connected on the
LAN ports. In this mode, the zNID 24xx can assign temporary (leased) IP
addresses to clients. Each DHCP client sends a request to the zNID 24xx for
an IP address lease. The zNID 24xx then assigns an IP address and lease time
to the client. The zNID 24xx keeps track of a range of assignable IP addresses
from a subnetwork.
Some customers choose to have the same IP address every time their DHCP
lease renews. This is known as sticky IP addresses. By default, the zNID 24xx
attempts to assign the same IP address to the same client on DHCP lease
renewal.
The DHCP server feature only works on routed interfaces. Typically, NAT
would also be enabled to map the private addresses from the DHCP server to
a public address.

zNID 24xx Series Configuration Guide 209

Configuration

Data services

Rate limiting
Rate limiting is done on a per-physical-port basis, not on a per-VLAN basis.
Rate limiting is a mechanism for controlling traffic and can include policing
(dropping packets). Use rate limiting to control the rate of traffic sent or
received on a physical port. Received traffic that is less than or equal to the
specified rate is forwarded and traffic that exceeds the rate plus the max burst
size is dropped.
After configuring an interface with rate limiting, the inbound traffic rate is
monitored and if the rate exceeds the specified rate, a pause frame will be sent
to the device connected to the port to stop the incoming traffic. If the
connected device does not support pause frames, then the excessive data will
be dropped.
The inbound and outbound rates are independent. This allows for symmetric
or asymmetric rates (to emulate ADSL for example). The rate limiting in
either direction can be disabled by entering 0 (zero) for the data rate.
For rate limits less than 100 Mbps, the rate can be set in 1Mbps increments.
For rate limits greater than 100 Mbps, the rate must be set in 8 Mbps
increments. The system will automatically adjust the value entered to an
appropriate rate if necessary.
For the outbound direction, the data will be sent at the rate specified.
Outbound data is mapped into different queues based on priority. Strict
Priority scheduling is used for the Critical priority queue and WRR
scheduling is used for the High, Medium and Low priority queues. The ratio
is 16 packets from the high priority queue, 8 from the medium queue and 4
from the low priority queue.
The max Burst Size parameter specifies how much a single burst of data can
exceed the inbound rate before packets are dropped. The default setting is
500k bytes.

Figure 166: Rate limits per interface

210 zNID 24xx Series Configuration Guide

 VLANS

Priority
The system can be configured to prioritize traffic based on either the layer 2
VLAN CoS bits or the layer 3 ToS bits. The prioritization method is selected
on the VLAN Mode page as shown below.

Figure 167: VLAN modes

The zNID 24xx products support the prioritization of traffic based on either
the ToS (Type of Service) values in IP packets or CoS (Class of Service)
values in Ethernet VLAN headers as defined by IETF RFC1349 and IEEE
802.1p respectively. The configured ToS or CoS levels specify packet priority
and queuing used to transport the packet through the Ethernet and IP
networks.

CoS
The VLAN header in Ethernet packets contains a CoS field for queuing
priority or Class of Service (CoS) values based on eight (0-7) levels of
service, with the lowest priority being 0 and the highest priority 7.
The eight priority values are mapped to 4 queues. The highest priority queue
(Critical) uses strict priority. All the packets in that queue will be sent before
any packets in the other queues. If there is a large amount of data in the strict
priority queue, it is possible that the lower priority queues never get serviced.
A weighted round robin approach is used for the remaining queues. The
packets are sent in a ratio of 16 high priority, 8 Medium, and 4 Low priority.

Table 58: CoS value to priority mapping

CoS Value Priority Queue Priority Method

0 Low WRR 16/8/4 (weight = 4)

1 Low WRR 16/8/4 (weight = 4)

2 Med WRR 16/8/4 (weight = 8)

3 Med WRR 16/8/4 (weight = 8)

6 Critical Strict priority

7 Critical Strict priority

Packets which require the highest throughput or are sensitive to latency (the
amount of time between received packets) should be in higher priority queues.
Normally video and voice are more sensitive to throughput and latency issues.

Precedence
IP packets have a ToS byte in their headers that contains information about
relative priority. The IP Precedence field contains a 3-bit priority designation.
Most normal traffic has an IP Precedence value of zero. Higher values in this
field indicate that traffic is more important and that it requires special treatment.
IP Precedence values greater than 5 are reserved for network functions.
The format of the ToS byte:

Precedence Values Priority Queue Priority Method

This chapter describes troubleshooting tests for the zNID 24xx. It includes the
following sections:
Zhone supports the Microsoft Media Room (MMR) application in many
deployments for GPON, ADSL and VDSL. Zhones IPTV deployment
includes support for integrated residential gateway functionality required by
MMR to significantly reduce the complexity and cost of deployments.
With any port, any service there is no need to designate some Ethernet Ports
as data ports and others as video ports. IPTV streams can be watched
from PCs using media streaming applications, or VoD and Pay per view
content may be viewed. Set top boxes (STBs) can join IPTV streams, access
VoD content or browse the Internet. Game consoles can access online gaming
over the Internet, browse the Internet, watch IPTV streams or access VoD
content.
This chapter includes the following sections
Microsoft Media Room support, page 213
Any port, any service, page 217

Microsoft Media Room support

MMR provides live, recorded, and on demand programming for PCs, mobile
phones and TV. All MMR client devices in the home must be able to discover
each other and communicate freely with each other. For this reason, all client
devices must be locally bridged with IP Addresses in the same subnet. For
security reasons, client devices in one customers home must not be able to
discover MMR client devices in other customers homes. As a result, NAT
Routing is required to provide firewall security.

zNID 24xx Series Configuration Guide 213

Special scenarios

Figure 168: MMR provides live, recorded, and on demand programming for PCs,
media servers (like the Xbox) and TV

The wire speed NAT Routing capabilities of Zhones zNID product family are
required to support multiple concurrent High Definition IP TV streams with
low latency and no packet loss. This is just one of the key attributes of the
zNID product line required to support the integrated MMR Home Gateway
capability.
There are several Residential Gateway requirements introduced by the MMR
application, and Zhones zNID 24xx supports them all.
The Zhone MMR application described in this document shows the high level
configuration items and describes how the zNID 24xx ONT provides data and
IPTV services to downstream set top boxes and media servers.
The MXK aggregates the services for Internet, IP video, and Video on
Demand (VoD) segregating the services by VLAN. The zNID uses the VLAN
segregation to provide video services to IPTV, Media server and PCs.

zNID Configuration requirements for MMR:

Two NAT BRouted VLANs must be created. All zNID LAN ports must
be UNTAGGED members of both VLANs. The zNID Uplink must be
TAGGED member of both. DHCP Server is enabled on the Data VLAN.
UPnP enabled on DATA VLAN.
IGMP Snooping must be enabled on the Video VLAN.
All local Ethernet traffic untagged, with Default PVID = Data VLAN,
IGMP PVID = Video VLAN.
All local devices have private IP addresses in the same subnet (assigned
by zNID DHCP server) and communicate freely with each other.
Conditional DHCP Addressing is used to assign permanent IP Address to
STBs and DVRs based on OUI classification. These devices are assigned
IP addresses from a dedicated range within the subnet.
All Data VLAN traffic is locally Bridged.
All LAN broadcast traffic is kept LOCAL.
Cross VLAN Routing must be enabled (for VoD traffic).
All upstream traffic on the Data VLAN is NAT Routed out the vlan500
vs. vlan600 WAN uplink based on Route Table lookup (based on Dest IP).
If there isn't a match in the Route Table, the Default Route will be to use
the Data VLAN.
Static Routes must be created for the IP Address ranges used for unicast
Video Traffic (e.g. VoD). DHCP Option 121 can create these
automatically.
Downstream unicast traffic from vlan500 and vlan600 is NAT Routed to
the vlan500 LAN side client device.
Downstream multicast video traffic on vlan600 is Bridged only to the
port(s) that JOINED the stream.
DNS Proxy must be enabled. Static DNS Entries must be configured for
discovery.iptv.microsoft.com, resolving to the IP Address of the Service
Provider's MMR Head End.
Static DNS Entries must be configured for any other Domain Names that
won't resolve using the Public DNS.

Any port, any service

Zhone supports the concept that any device connected to the zNID 24xx can
access any service, whether that service is high speed Internet (HSIA), IPTV
or Video on Demand (VoD) from any Ethernet port. With up to four Gigabit
Ethernet ports as well as two POTS port there is enough bandwidth to supply
HSIA, IPTV and VoD as well as analog telephone.
With any port, any service there is no need to designate some Ethernet Ports
as data ports and others as video ports. IPTV streams can be watched
from PCs using media streaming applications, or VoD and Pay per view
content may be viewed. Set top boxes (STBs) can join IPTV streams, access
VoD content or browse the Internet. Game consoles can access online gaming

This chapter describes troubleshooting tests for the zNID 24xx. It includes the
following sections:
Diagnostics, page 219
Ping, page 221
Trace route, page 222
Hardware reset, page 224

Diagnostics
The Diagnostics page runs tests on each interface. If a test shows FAIL, click
the Hints link to diagnose the issue.

Figure 171: The Diagnostics page

The Ethernet connection test checks whether the zNID detects a device
connected, so the hints will be cabling and whether the device is running
properly. Restarting most devices will put them in a known state.

Parameter Description

IP Address or Domain The destination address can be entered as a dot notation

Name IP address (i.e. 135.20.3.40) or a Domain Name to be
looked up on the configured Domain Name Server.

Length of packet The number of bytes in the IP Payload portion of the

packet. Additional bytes for packet overhead are
normally added as well so the length of the overall
packet is longer. Setting the value larger than 64 can
determine problems in a network that restrict large
packets. The default is 64. Setting the value larger than
64 can determine problems in a network that restrict
large packets. The default is 64.

Count The number of pings to be sent before the test

completes. A large number will allow the user to verify
network connectivity during certain testing. The default
is 4.
