FTOS(conf)# interface vlan 10
FTOS(conf-if-vlan)# mode remote-port-mirroring
A remote port mirroring session mirrors Layer 2 and Layer 3 traffic by prefixing the reserved VLAN
tag to monitored packets so that they are copied to the reserve VLAN.
Mirrored traffic is transported across the network using 802.1Q-in-802.1Q tunneling. The source
address, destination address and original VLAN ID of the mirrored packet are preserved with the
tagged VLAN header. Untagged source packets are tagged with the reserved VLAN ID.
There is no restriction on the VLAN IDs used for the reserved remote-monitoring VLAN. Valid VLAN
IDs are 1 to 4094. The default VLAN ID is not supported.
The reserved VLAN for remote port mirroring can be automatically configured in intermediate
switches by using GVRP.
MAC address learning in the reserved VLAN is automatically disabled.
To change the reserved VLAN used in a source session, you can remove the current VLAN by entering
