Interfaces Information

The show interfaces command is useful for gathering information on the sensing and command and
control interfaces. This section describes the show interfaces command, and contains the following
topics:
•
•

Understanding the show interfaces Command

You can learn the following information from the show interfaces command:
•
•
•
•
The show interfaces command displays statistics for all system interfaces. Or you can use the individual
commands to display statistics for the command and control interface (show interfaces
command_control_interface_name), the sensing interface (show interfaces interface_name).

Interfaces Command Output

The following example shows the output from the show interfaces command:
sensor# show interfaces
