• You can configure additional destination ports in an active session.• You can tunnel the mirrored traffic from multiple remote-port source sessions to the same destination port.• By default, destination port sends the mirror traffic to the probe port by stripping off the rpm header. We can also configure thedestination port to send the mirror traffic with the rpm header intact in the original mirror traffic..• By default, ingress traffic on a destination port is dropped.RestrictionsWhen you configure remote port mirroring, the following restrictions apply:• You can configure the same source port to be used in multiple source sessions.• You cannot configure a source port channel or source VLAN in a source session if the port channel or VLAN has a member portthat is configured 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 asthe destination port.• A destination port cannot be used in any spanning tree instance.• The reserved VLAN used to transport mirrored traffic must be a L2 VLAN. L3 VLANs are not supported.• On a source switch on which you configure source ports for remote port mirroring, you can add only one port to the dedicatedRPM VLAN which is used to transport mirrored traffic. You can configure multiple ports for the dedicated RPM VLAN onintermediate and destination switches.Displaying Remote-Port Mirroring ConfigurationsTo display the current configuration of remote port mirroring for a specified session, enter the show config command in MONITORSESSION configuration mode.Dell(conf-mon-sess-2)#show config!monitor session 2 type rpmsource fortyGigE 1/52 destination remote-vlan 300 direction rxsource Port-channel 10 destination remote-vlan 300 direction rxno disableTo display the currently configured source and destination sessions for remote port mirroring on a switch, enter the show monitorsession command in EXEC Privilege mode.Dell(conf)#do show monitor sessionSessID Source Destination Dir Mode Source IP Dest IP------ ------ ----------- --- ---- --------- --------1 remote-vlan 100 Fo 1/32 N/A N/A N/A N/A1 remote-vlan 100 Po 100 N/A N/A N/A N/A2 Fo 1/4 remote-vlan 300 rx Port N/A N/A2 Po 10 remote-vlan 300 rx Port N/A N/ATo display the current configuration of the reserved VLAN, enter the show vlan command.Dell#show vlanCodes: * - Default VLAN, G - GVRP VLANs, R - Remote Port Mirroring VLANs, P - Primary, C -Community, I - IsolatedO - OpenflowQ: U - Untagged, T - Taggedx - Dot1x untagged, X - Dot1x taggedo - OpenFlow untagged, O - OpenFlow taggedG - GVRP tagged, M - Vlan-stacki - Internal untagged, I - Internal tagged, v - VLT untagged, V - VLT taggedNUM Status Description Q Ports* 1 InactiveR 100 Active T Fo 1/20R 300 Active T Fo 1/24Port Monitoring 551
