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, page C-93
•
Interfaces Command Output, page C-94
•
Displaying Interface Traffic History, page C-94

Understanding the show interfaces Command

You can learn the following information from the show interfaces command:
•
Whether the interface is up or down
•
Whether or not packets are being seen, and on which interfaces
•
Whether or not packets are being dropped by SensorApp
•
Whether or not there are errors being reported by the interfaces that can result in packet drops
The show interfaces command displays statistics for all system interfaces. Or you can use the individual
commands to display statistics for the comm and and control interface (show interfaces
command_control_interface_name), the sensing interface (show interfaces interface_name).
