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, and show interface <port-number > commands. They do not appear in the output of other show 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.)
