Identifying physical IRF ports on the member switches
Identify the 1/10-GE Ethernet ports, SFP+ ports, and QSFP+ ports to be used for IRF connections on
the member switches according to your topology and connection scheme.
All the 1/10-GE Ethernet ports, SFP+ ports, and QSFP+ ports on the HPE FlexFabric 5930 switch
can be used for IRF connections.
Planning the cabling scheme
You can use twisted pair cables, SFP+/QSFP+ network cables, or SFP+/QSFP+ transceiver
modules and optical fibers to connect the switches for IRF connections. If the IRF member switches
are far away from one another, choose the SFP+/QSFP+ transceiver modules and optical fibers. If
the IRF member switches are all in one equipment room, choose twisted pair cables or
SFP+/QSFP+ cables. For more information about available transceiver modules and cables, see
"Appendix C Ports and LEDs."
The followin
g subsections describe several IRF connection schemes recommended by Hewlett
Packard Enterprise, and all these schemes use a ring topology.
Connecting the IRF member switches in one rack
Figure 47 shows an example for connecting four IRF member switches in a rack by using QSFP+
network cables and QSFP+ transceiver modules and optical fibers. The switches in the ring topology
(see Figure 48) are in the same order a
s 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.
