Configuring and operating rules for friendly port names
At either the global or context configuration level, you can assign a unique name to a port. You can also assign the same name to multiple ports.
The friendly port names you configure appear in the output of the
show name
[port-list],show config
, andshow interface <port-number >
commands. They do not appear in the output of othershow
commands or in Menu interface screens. (See Displaying friendly port names with other port data (CLI).)Friendly port names are not a substitute for port numbers in CLI commands or Menu displays.
Trunking ports together does not affect friendly naming for the individual ports. (If you want the same name for all ports in a trunk, you must individually assign the name to each port.)
A friendly port name can have up to 64 contiguous alphanumeric characters.
Blank spaces within friendly port names are not allowed, and if used, cause an invalid input error. (The switch interprets a blank space as a name terminator.)
In a port listing, not assigned indicates that the port does not have a name assignment other than its fixed port number.
To retain friendly port names across reboots, you must save the current running-configuration to the startup-config file after entering the friendly port names. (In the CLI, use the
write memory
command.)
