Concept 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 TenGigE 1/52 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
SessID Source Destination Dir Mode Source IP Dest IP

2 Te 1/50 remote-vlan 300 rx Port N/A N/A
2 Po 10 remote-vlan 300 rx Port N/A N/A
To display the current conguration of the reserved VLAN, enter the show vlan command.

Conguring the Sample Remote Port Mirroring
Remote port mirroring 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).
