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.
