Configuring a destination switch in a remote mirroring 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.


mirror endpoint ip src-ip src-udp-port dst-ip exit-port-# no mirror endpoint ip src-ip src-udp-port dst-ip

Used on a destination switch to configure the remote endpoint of a mirroring session. The command uniquely associates the mirrored traffic from the desired session on a monitored source with a remote exit port on the destination switch. You must use the same set of source and destination parameters used when you configure the same session on both the source and destination switches.

For a given mirroring session, the same src-ip , src-udp-port and dst-ip values must be entered with the mirror endpoint ip command on the destination switch, and later with the mirror remote ip command on the source switch.


Do not remove the configuration of a remote mirroring endpoint support for a given session if there are source switches currently configured to mirror traffic to the endpoint.


Must exactly match the src-ip address you configure on the source switch for the remote session.


Must exactly match the src-udp-port value you configure on the source switch for the remote session. The recommended port range is 7933 to 65535.This setting associates the monitored source with the desired remote endpoint in the remote session by using the same, unique UDP port number to identify the session on the source and remote switches.


Must exactly match the dst-ip setting you configure on the source switch for the remote session.


Exit port for mirrored traffic in the remote session, to which a traffic analyzer or IDS is connected.

The no form of the command deletes the mirroring endpoint for the configured session on the remote destination switch.
