Port Status and Configuration

Using Friendly (Optional) Port Names

Syntax: show config

Includes friendly port names in a listing of all interfaces (ports) configured with non-default settings. Excludes ports that have neither a friendly port name nor any other non-default configuration settings.

For example, if you configure port A1 with a friendly port name:

This command sequence saves the friendly port name for port A1 in the startup­ config file. The name entered for port A2 is not saved because it was executed after write memory.

Listing includes friendly port name for port A1 only.

In this case, show config lists only port A1. Executing write mem after entering the name for port A2, and then executing show config again would result in a listing that includes both ports.

Configuring Transceivers and Modules That Haven’tBeen InsertedTransceivers

Previously, a port had to be valid and verified for the switch to allow it to be configured. Transceivers are removable ports and considered invalid when not present in the switch, so they cannot be configured unless they are already in the switch. For switches covered in this guide, the verification for allowable port configurations performed by the CLI is removed and configuration of transceivers is allowed even if they are not yet inserted in the switch.
