Traffic mirroring overview

Traffic mirroring (Intelligent Mirroring) allows you to mirror (send a copy of) network traffic received or transmitted on a switch interface to a local or remote destination, such as a traffic analyzer or IDS.)

Traffic mirroring provides the following benefits:

  • Allows you to monitor the traffic flow on specific source interfaces.

  • Helps in analyzing and debugging problems in network operation resulting from a misbehaving network or an individual client. The mirroring of selected traffic to an external device makes it easier to diagnose a network problem from a centralized location in a topology spread across a campus.
