Displaying the Port Name for an Interface

You can use the show interface brief command to display the name assigned to the port. If any of the ports have long port names, they are truncated. To show full port names, use the show interfaces brief wide command.

device# show interfaces brief
Port    Link    State   Dupl Speed Trunk Tag Pvid Pri MAC 																			  Name
1/1/23  Up      Forward Full 1G    None  No  1    0   748e.f82d.7a16 connected- 
1/1/47  Up      Forward Full 1G    None  No  1    0   748e.f82d.7a2e
mgmt1   Up      None    Full 1G    None  No  None 0   748e.f82d.7a00

In this output, the port name for interface 1/1/23 is truncated.

Use the show interface brief wide command to avoid truncating long port names.
