Dell SmartFabric OS10 User Guide Release 10.5.3

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
