room, use QSFP28/QSFP+/QSFP+ to SFP+/SFP+ network cables for IRF connections. For more
information about available transceiver modules and cables, see
The following subsections describe several IRF connection schemes. As a best practice, use the ring
topology for IRF connections.
Connecting the IRF member switches in one rack
Figure 37 shows an example for connecting four IRF member switches in a rack by using QSFP28
network cables and QSFP28 transceiver modules and optical fibers. The switches in the ring

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.
Figure 39 shows an example for connecting four top of rack IRF member switches by using QSFP28
network cables and QSFP28 transceiver modules and optical fibers. The topology is the same
as Figure 38.
