Configuring the Interoperability of Modules for Unicast Routing

This chapter describes how to configure the interoperability of F1 Series modules with M Series modules for unicast routing on the Cisco NX-OS device.

This chapter includes the following sections:

Information About the Interoperability of Modules for Unicast Routing

A mixed chassis is a Cisco Nexus 7000 Series chassis that contains at least one F1 Series module and at least one M Series module. Because the F1 Series module processes only Layer 2 traffic, you must configure it to pass Layer 3 traffic through the chassis.

Licensing Requirements for the Interoperability of Modules for Unicast Routing

The following table shows the licensing requirements for this feature:

 

Product
License Requirement

Cisco NX-OS

The interoperability of modules for unicast routing requires no license. Any feature not included in a license package is bundled with the Cisco NX-OS system images and is provided at no extra charge to you. For a complete explanation of the Cisco NX-OS licensing scheme, see the Cisco NX-OS Licensing Guide .

Guidelines and Limitations for the Interoperability of Modules for Unicast Routing

The interoperability of modules for unicast routing has the following configuration guidelines and limitations:

  • You cannot use F2 or F2e Series modules in the Cisco Nexus 7000 Series chassis to run Layer 3 routing with the F1 Series module.

Configuring the Interoperability of Modules for Unicast Routing

To configure a Layer 3 gateway in a mixed chassis, you use the proxy routing functionality. You enable routing on a specific VLAN by configuring a VLAN interface, and the system automatically provides load-balanced routing functionality. See the Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide for more information about Layer 3 routing and VLAN interfaces.

For interoperability between F1 Series and M Series modules, use the following procedure to specify which physical interfaces on the M Series modules you want to use for Layer 3 routing.

BEFORE YOU BEGIN

You must configure a VLAN interface for each VLAN on the F1 Series module that you want to use with the proxy-routing functionality in a mixed chassis.

You must have interfaces from both the M Series modules and the F1 Series modules in the same VDC.

SUMMARY STEPS

1. configure terminal

2. hardware proxy layer-3 routing {use | exclude} { module mod-number | interface slot/port} [ module-type f1 ]

3. (Optional) show hardware proxy layer-3 detail

4. (Optional) copy running-config startup-config

DETAILED STEPS

 

Command
Purpose

Step 1

configure terminal

 

Example:

switch# configure terminal

switch(config)#

Enters global configuration mode.

Step 2

hardware proxy layer-3 routing { use | exclude } { module mod-number | interface slot/port } [ module-type f1 ]

 

Example:

switch(config)# hardware proxy layer-3 routing use module 1, 2-6, 7

Configures specific modules and physical interfaces on the M Series module to provide the proxy routing on the F1 Series module.

Step 3

show hardware proxy layer-3 detail

 

Example:

switch(config)# show hardware proxy layer-3 detail

(Optional) Displays information about the proxy Layer 3 functionality.

Step 4

copy running-config startup-config

 

Example:

switch(config)# copy running-config startup-config

(Optional) Copies the running configuration to the startup configuration.

Verifying the Configuration for the Interoperability of Modules for Unicast Routing

To display the interoperability of modules for unicast routing configuration, perform one of the following tasks:

 

Command
Purpose

show hardware proxy layer-3 counters {brief | detail}

Displays the number of packets sent by F1 Series modules to each M Series module for proxy forwarding.

command to clear the counters.

show hardware proxy layer-3 detail

Displays information about proxy routing from an F1 Series module to an M Series module in a chassis that contains both types of modules.

Configuration Examples for the Interoperability of Modules for Unicast Routing

This example shows how to specify physical interfaces on M Series modules to perform proxy routing on F1 Series modules in a mixed chassis:

switch# configure terminal
switch(config)# hardware proxy layer-3 routing use module 1, 7
switch(config)# show hardware proxy layer-3 detail
