You connect the IRF member switches through IRF ports, the logical interfaces for the connections
between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port
2. To use an IRF port, you must bind a minimum of one physical port to it.
When connecting two neighboring IRF member switches, you must connect the physical ports of
IRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch.
As a best practice to avoid loop topology, first complete IRF configuration and then connect the IRF
member switches.
The HPE 5130 HI switches can provide 10-GE IRF connections through SFP+ ports, and you can
bind several SFP+ ports to an IRF port for increased bandwidth and availability.
Figure 39 an
d Figure 40 show the topologies of an IRF fabric made up of three HPE 5130 24G
4SFP+ 1-slot HI switches. The IRF port connections in the two figures are for illustration only, and
more connection methods are available.

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