When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port
1 on one switch to the physical ports of IRF-port 2 on the other switch.
You can create an IRF fabric in daisy chain topology or more reliable ring topology. In ring topology, the
failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Instead, the IRF
fabric changes to a daisy chain topology without interrupting network services.
Figure 32 and Figure 33 show the topologies of an IRF fabric made up of three switches. The IRF port
connections in the two figures are for illustration only, and more connection methods are available.
For information about the physical ports available for IRF connections on the switch, see "
Determining
physical IRF ports on the member switches ."
