The following subsections describe several H3C recommended IRF connection schemes. All these

schemes use a ring topology.

IMPORTANT:

In these schemes, all physical IRF ports are located on the same side. If physical IRF ports are on different
sides, you must measure the distance between them to select an appropriate cable.

Connecting the IRF member switches in one rack

Use short-haul and long-haul SFP+ cables to connect the IRF member switches (four switches in this

example) in a rack as shown in

Figure 49

. The switches in the ring topology (see

Figure 51

) are in the

same order as connected in the rack.
