• Maximum number of destination sessions supported on a switch: 64 • Maximum number ports supported in a destination session: 64. • You can configure any port as a destination port. • You can configure additional destination ports in an active session. • You can tunnel the mirrored traffic from multiple remote-port source sessions to the same destination port. • By default, destination port sends the mirror traffic to the probe port by stripping off the rpm header. We can also configure the destination port to send the mirror traffic with the rpm header intact in the original mirror traffic.. • By default, ingress traffic on a destination port is dropped. Restrictions When you configure remote port mirroring, the following restrictions apply: • You can configure the same source port to be used in multiple source sessions. • You cannot configure a source port channel or source VLAN in a source session if the port channel or VLAN has a member port that is configured as a destination port in a remote-port mirroring session. • A destination port for remote port mirroring cannot be used as a source port, including the session in which the port functions as the destination port. • A destination port cannot be used in any spanning tree instance. • The reserved VLAN used to transport mirrored traffic must be a L2 VLAN. L3 VLANs are not supported. • On a source switch on which you configure source ports for remote port mirroring, you can add only one port to the dedicated RPM VLAN which is used to transport mirrored traffic. You can configure multiple ports for the dedicated RPM VLAN on intermediate and destination switches. Displaying Remote-Port Mirroring Configurations To display the current configuration of remote port mirroring for a specified session, enter the show config command in MONITOR SESSION configuration mode.
