For more information about available cables, see " Appendix C Ports and LEDs ."
The following subsections describe several IRF connection schemes by using the QSFP28 cables
and QSFP28 transceiver modules and fibers. As a best practice, use the ring topology for IRF
connections.
Connecting the IRF member switches in one rack
Figure 34 shows an example for connecting four IRF member switches in a rack. The switches in the
ring topology (see Figure 35 ) are in the same order as connected in the rack.

Connecting the IRF member switches in a ToR solution
You can install IRF member switches in different racks side by side to deploy a top of rack (ToR)
solution.
