Failure
Manual: TX Power Fixed;
Radio Branch: Powers
Automatic: ATPC enabled
ATPC allows Ptx<PtxMAX for most of
the time; when fading occurs, Ptx is RTPC
increased as needed until the
maximum is reached. Zona ACM ATPC reduce Ptx
ATPC vs constant Ptx:
- Less power consumption,
- higher MTBF, Ptx doesn’t change
- reduced interference on other links
ATPC increse Ptx up to the max Ptx value

 Routing Table
As a Layer 3 router, the equipment uses a Routing Table to route
the management traffic through its ports (RADIO and LAN).

“Routing table” is used for view delete)

the actual routing mapped Static: command inserted manually by the user (Can be delete)
OSPF: command inserted automatically by OSPF feature

- Destination: is the Network address to send /receive management traffic.

- Subnet Mask: Network Mask of the destination network.
- Gateway: is the next IP address interface that connect the Destination's net.
- Interface: defines the local mngt interface that allows to reach the next hop
- Protocol: specifies how the routing row has been inserted.

 Layer 2 protocol Tunneling

When protocol tunneling is enabled, edge switches on the inbound side of the service-provider network
encapsulate Layer 2 protocol packets with a special MAC address and send them across the
service-provider network. Core switches in the network do not process these packets but forward them
as normal packets.You can enable Layer 2 protocol tunneling (by protocol) on the ports that are
connected to the customer in the edge switches of the service-provider network.

802.1p: From 0 up to 7 assigned to

untagged packets arriving at the port

The incoming untagged packet are

tagged with PVID of the interface

The frame is discarded if this port is not a member of the VLAN with which this frame is associated.
All frames are forwarded in accordance with the 802.1Q VLAN bridge specification.

All frame types are accepted at ingress (tagged or untagged) and are assigned with the PVID
Only tagged frames present in the VLAN table
Only Untagged frames 31
