Information About Interfaces

The main function of a switch is to relay frames from one data link to another. To relay the frames, the 
characteristics of the interfaces through which the frames are received and sent must be defined. The 
configured interfaces can be Fibre Channel interfaces, Gigabit Ethernet interfaces, the management 
interface (mgmt0), or VSAN interfaces.
