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:
Figure 10-19. Example Listing of the Startup-Config File with a Friendly Port Name Configured (and Saved)
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.
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.
Listing includes friendly
port name for port A1
only.
Configuring Transceivers and Modules That Haven’t
Been Inserted
Transceivers
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.
