Quick reference to remote mirroring setup

The commands beginning with Destination mirror on a remote switch, configure mirroring for a remote session in which the mirroring source and destination are on different switches:

  • The mirror command identifies the destination in a mirroring session.

  • The interface and vlan commands identify the monitored interface, traffic direction, and traffic-selection criteria for a specified session.


When configuring a remote mirroring session, always configure the destination switch first. Configuring the source switch first can result in a large volume of mirrored, IPv4-encapsulated traffic arriving at the destination without an exit path, which can slow switch performance.
