Introduction
This document provides examples for setting up IRF fabrics and configuring link aggregation and
routing on the IRF fabrics.
Prerequisites
The configuration examples in this document were created and verified in a lab environment, and all
the devices were started with the factory default configuration. When you are working on a live
network, make sure you understand the potential impact of every command on your network.
This document assumes that you have basic knowledge of IRF.
General restrictions and guidelines
When you set up and configure an IRF fabric, follow the restrictions and guidelines in this section.
This section provides only the basic restrictions and guidelines that ensure a successful IRF
deployment. For complete information, see IRF configuration guide for the switch.
Hardware requirements
An S12500X-AF switch can form an IRF fabric only with devices of the same model. In addition, an
S12500X-AF switch that uses type-H service modules cannot form an IRF fabric with an
S12500X-AF switch that uses type-F service modules.
An S12500-X switch can form an IRF fabric only with devices of the same model.
An S9800 switch can form an IRF fabric only with devices of the same model.
An S12500X-AF, S12500-X, or S9800 IRF fabric can contain a maximum of two member devices.
As a best practice, the following card deployment items are the same across member chassis:
•
Number of cards installed on each chassis.
•
Card models.
•
Slot numbers for the same type of cards.
The following matrix shows the IRF member ID and hardware compatibility:
