Port Mirroring
The port mirror is a management tool that allows you to monitor the traffic
on one or more ports on the switch. It works by copying the traffic from
source ports to a destination port where the traffic can be monitored with a
network analyzer. The port mirror can be used to troubleshoot network
problems or to investigate possible unauthorized network access. The
performance and speed of the switch is not affected by the port mirroring
feature.
This chapter provides a brief description of the port mirroring feature and
explains how to display and set port mirroring. See the following sections:
