Administrator Guide

• 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

Configuration procedure for Remote Port Mirroring
To configure remote port mirroring, you must configure:
1. A reserved VLAN used to transport mirrored packets on source, intermediate, and destination switches
2. A source session that consists of multiple source ports, port channels, and VLANs which are associated with the dedicated VLAN and
located on different source switches
3. A destination session that consists of multiple destination ports associated with the dedicated VLAN and located on different
destination switches
