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.
The IRF port connections in the two figures are for illustration only, and more connection methods
are available.
