This command has options to display the interface status, IP and MAC addresses, and multiple counters for the amount and type of
traffic passing through the interface.
If you configured a port channel interface, this command lists the interfaces configured in the port channel.
NOTE:
To end output from the system, such as the output from the show interfaces command, enter CTRL+C and
Dell Networking OS returns to the command prompt.
NOTE: The CLI output may be incorrectly displayed as 0 (zero) for the Rx/Tx power values. To obtain the correct
power information, perform a simple network management protocol (SNMP) query.
The following example shows the configuration and status information for one interface.
