Identifying physical IRF ports on the member switches

Identify the physical IRF ports on the member switches according to your topology and connection
scheme.
Table 7 shows the physical ports that can be used for IRF connection and the port use restrictions.

Planning the cabling scheme

Use twisted pair cables, SFP+ network cables, or SFP+ transceiver modules and fibers to connect
the IRF member switches. If the IRF member switches are far away from one another, choose SFP+
transceiver modules with optical fibers. If the IRF member switches are all in one equipment room,
choose twisted pair cables or SFP+ network cables. For more information about SFP+ network
cables and SFP+ transceiver modules, see
The following subsections describe several recommended IRF connection schemes, and all these
schemes use a ring topology.
Connecting the IRF member switches in one rack
Use SFP+ network cables to connect the IRF member switches (9 switches in this example) in a rack
as shown in
connected in the rack.
