Establishment of an IRF Fabric
Topology and connections of an IRF fabric
An IRF fabric typically has a ring topology structure. As shown in Figure 1-2 , each switch has two ports
connected with two other switches in the fabric. These two ports are called fabric ports in general, a left
port and a right port respectively; the other ports, which are available for connections with users or
devices outside the fabric, are called user ports.

A correctly built IRF fabric features the following:
z Multiple S3600 series switches are interconnected through their fabric ports.
z Given a switch, its left port is connected to the right port of another switch, and its right port is
connected to the left port of a third one.
