• 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.

Configuring Remote Port Monitoring
Remote port monitoring 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).
To configure a remote-port monitoring session:
Step Command Description
1
configure terminal Enter global configuration mode.
2
monitor session id type rpm Specify a unique session ID number and RPM as the session type,
and enter Monitoring-Session configuration mode.
3
source {interface | range} destination
interface direction {rx | tx | both}
Enter a source port or a range of source port interfaces to be
monitored. Enter the destination port interface. Specify ingress
