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 A-87
Interfaces Command Output, page A-87
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 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#
