Source session
Configure physical ports and port channels as sources in remote port monitoring and use them in the same source session.
You can use both L2, configured with the switchport command, and L3 ports as source ports. Optionally, to monitor the
configured VLAN traffic on source ports, configure one or more source VLANs.
Use the default VLAN and native VLANs as a source VLAN.
You cannot configure the dedicated VLAN used to transport mirrored traffic as a source VLAN.
Configure remote port monitoring
Remote port monitoring requires the following for transporting mirrored traffic configured on the source, intermediate, and
destination devices:
A source interface
Monitored ports on different source network devices
A reserved tagged VLAN
1. Create a remote monitoring session in CONFIGURATION mode.
monitor session session-id type rpm-source
2. Enter the source to monitor traffic in MONITOR-SESSION mode.
source interface interface-type {both | rx | tx}interface-range direction
3. Enter the destination to send the traffic to in MONITOR-SESSION mode.
destination remote-vlan vlan-id
4. Enable the monitoring interface in MONITOR-SESSION mode.
no shut
Create remote monitoring session
OS10(config)# monitor session 10 type rpm-source
OS10(conf-mon-rpm-source-10)#
Configure source and destination port, and traffic direction

NOTE: This is the interface through which the traffic is sent to the source and is monitored.
