This command was modified in Cisco MDS SAN-OS Release 1.3(1).

You can specify a range of interfaces by issuing a command with the following example format:

interface fc1/1 - 5 , fc2/5 - 7

The spaces are required before and after the dash ( - ) and before and after the comma ( , ).

The show interface interface-type slot/port transceiver command can only be issued on a switch in the Cisco MDS 9100 Series if the FCOT is present.

The following example displays information for a Fibre Channel interface.

switch# show interface fc1/11 fc1/11 is up
