port is a logical interface for the connection between IRF member devices. Every IRF-capable device supports two IRF ports. The IRF ports are named IRF-port n/1 and IRF-port n/2, where n is the member ID of the switch. The two IRF ports are referred to as "IRF-port 1" and "IRF-port 2" in this - HP 6125G | HP 6125G & 6125G/XG Blade Switches IRF Configuration Guide-R2 - Page 7
