Setting 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 designated ports to another 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 mirror.

This chapter provides a brief description of the port mirroring feature and explains how to display and set port mirroring. See the following sections:
