Setup Guide

• 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.
• On a source switch on which you congure source ports for remote port mirroring, you can add only one port to the dedicated RPM
VLAN which is used to transport mirrored trac. You can congure multiple ports for the dedicated RPM VLAN on intermediate and
destination switches.
Displaying Remote-Port Mirroring Congurations
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.
DellEMC(conf-mon-sess-2)#show config
!
monitor session 2 type rpm
source fortyGigE 1/32/1 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.
DellEMC(conf)#do show monitor session

Conguration procedure for Remote Port Mirroring
To congure remote port mirroring, you must congure:
1 A reserved VLAN used to transport mirrored packets on source, intermediate, and destination switches
2 A source session that consists of multiple source ports, port channels, and VLANs which are associated with the dedicated VLAN and
located on dierent source switches
3 A destination session that consists of multiple destination ports associated with the dedicated VLAN and located on dierent
destination switches
