Remote destinations
A remote mirroring traffic destination is an switch configured to operate as the exit switch for mirrored traffic sessions originating on other switches.
CAUTION:
After you configure a mirroring session with traffic-selection criteria and a destination, the switch immediately starts to mirror traffic to each destination device connected to an exit port. In a remote mirroring session that uses IPv4 encapsulation, if the intended exit switch is not already configured as the destination for the session, its performance may be adversely affected by the stream of mirrored traffic. For this reason, Switch strongly recommends that you configure the exit switch for a remote mirroring session before configuring the source switch for the same session.
