This object sets the RSPAN VLAN ID used to tag mirrored traffic when this session acts as an RSPAN source, working together with dPktMonSessionDestInterface. Setting it to a valid VLAN ID between 2 and 4094 causes the switch to tag mirrored packets with that RSPAN VLAN as they leave the destination port toward the remote monitoring device; setting it to 0 leaves the RSPAN VLAN unspecified and traffic is sent untagged instead. An admin forwarding mirrored traffic across the network to a remote packet analyzer would set dPktMonSessionDestRemoteVlanId to 999, so all mirrored frames carry VLAN tag 999 en route.
