Nexus Switches Overview

The document provides information about Cisco Nexus 7000 and 7700 series switches. It discusses the key components of Nexus 7000 switches including the chassis, I/O modules, supervisor engines, and fabric modules. It also compares the Nexus 7000 and 7700 series switches in terms of supported port density, chassis designs, and supervisor engine models. Specifically, it notes that the Nexus 7718 switch can provide up to 90 terabits per second of total switching capacity.

Cisco Nexus Training

Cisco Nexus 9000, 7000, 5000, 2000


Introduction to Nexus Switches

• These switches are designed for data-centers which support and provide High Availability,
High Performance, Infrastructure Scalability, Operational Continuity.
• These are designed for wide range of datacentre deployments, mainly focused on high
density and performance, mission-critical enterprise and service provider deployments.
• These switches offer most comprehensive data center network feature sets in a single
platform.
• There are 8 categories of these hardware – Nexus 9000, 7000, 6000, 5000, 4000, 3000,
2000, 1000
1. Nexus 7000 switches offer a full feature
set in a highly resilient modular
platform.
2. These are two different hardware
platforms, so remember that the
Cisco Nexus components of 7000 series can’t be
used in 7700 series and vice-versa.
7000/7700 3. Both Cisco Nexus 7000 and Cisco 7700
series datacenter switch
models support 1, 10,40 and 100 Gbps
port density.
4. There are mainly four components in
nexus 7000 switches – Chassis, I/O
modules, Supervisor Engines and Fabric
Modules.
5. Chassis is basically a house for all
modules, Sup engines, Fabric modules ,
power supplies and Fan modules and
provides Cooling and power infrastructure
to everything inside the chassis.

Cisco Nexus 6. I/O modules are line cards ( M & F Series)


which provide data plane forwarding to the
7000/7700 switches.
7. Supervisor Engine is brain of the switch
and provide management and control plane
functions.
8. Fabric Modules provide high bandwidth
inter-connection between I/O modules.

Comparison Nexus 7000 & 7700
Calculating Total Switching capacity for 7718

It has 2.8 Tbps bandwidth per slow and 16 I/O modules

So total Switching capacity = 2.8 * 16 * 2 ( full duplex operation) =


89.6Tbps ~= 90Tbps

Fabric Module
• Note, Chassis 7004, 7702 do not require Fabric Module as it is inbuilt.
Supervisor Engine

• The supervisor engine is brain of the switch that controls the Layer 2 and 3 services, redundancy
capabilities, configuration management, status monitoring, power and environmental management,
and more.
• Management functions are Telnet, SSH, SNMP etc.
• Control plane functions like traffic of Routing Protocols, Spanning-Tree, LACP port channel etc.
• The Cisco Nexus 7000 Supervisor Module incorporates highly advanced analysis and debugging
capabilities
• The supervisor module uniquely provides a built-in packet capture and protocol decoding tool that
allows analysis of control plane traffic to improve network planning, provide faster operation
response times to events, and reduce operating costs.
