View Basic Interface Information
To view basic interface information, use the following command.
You have several options for viewing interface status and configuration parameters.
● Lists all configurable interfaces on the chassis.
EXEC mode
show interfaces
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 EMC 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.
