Port Status and Basic Configuration
Viewing Port Status and Configuring Port Parameters
From the CLI, you can configure and view all port parameter settings and view
all port status indicators.
Using the CLI To View Port Status
Use the following commands to display port status and configuration:
■ show interfaces brief: Lists the full status and configuration for all ports
on the switch.
■ show interface config: Lists a subset of the data shown by the show
interfaces command (above); that is, only the enabled/disabled, mode, and
flow control status for all ports on the switch.
Syntax: show interfaces [ brief | config ]
These two commands display the information listed in
table
10-2, below.
