Setup Guide

• You can congure the same source port to be used in multiple source sessions.
• You cannot congure a source port channel or source VLAN in a source session if the port channel or VLAN has a member port that is
congured as a destination port in a remote-port mirroring session.
• 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 trac must be a L2 VLAN. L3 VLANs are not supported.
Displaying a Remote-Port Mirroring Conguration
To display the current conguration of remote port mirroring for a specied session, enter the show cong command in MONITOR
SESSION conguration mode.
Dell(conf-mon-sess-2)#show config
!
monitor session 2 type rpm
source fortyGigE 0/60 destination remote-vlan 300 direction rx
source Port-channel 10 destination remote-vlan 300 direction rx
no disable
To display the currently congured source and destination sessions for remote port mirroring on a switch, enter the show monitor session
command in EXEC Privilege mode.
Dell(conf)#do show monitor session

To display the current conguration of the reserved VLAN, enter the show vlan command.

Conguring Remote Port Monitoring
Remote port monitoring requires a source session (monitored ports on dierent source switches), a reserved tagged VLAN for transporting
mirrored trac (congured on source, intermediate, and destination switches), and a destination session (destination ports connected to
analyzers on destination switches).
