Identifying physical IRF ports on the member switches

Identify the physical IRF ports on the member switches according to your topology and connection

scheme.

Planning the cabling scheme

Use SFP+ DAC 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 the SFP+ transceiver modules with optical

fibers. If the IRF member switches are all in one equipment room, choose SFP+ DAC cables.
H3C recommends that you use ring topology to connect the switches. The following describes cabling

schemes in ring topology.

Connecting the IRF member switches in one rack

Use SFP+ DAC cables to connect the IRF member switches (9 switches in this example) in a rack as shown

in

Figure 30

. The switches in the ring topology (see

Figure 31

) are in the same order as connected in the

rack.
