Users 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

Configuring the Sample Remote Port Mirroring
Remote port mirroring requires a source session (monitored ports on different source switches), a reserved tagged VLAN for
transporting mirrored traffic (configured on source, intermediate, and destination switches), and a destination session
(destination ports connected to analyzers on destination switches).
