properties. For more information, see "Configuring Multiservice Physical Interface

Removing MPLS Labels from Incoming Packets
The JUNOS Software can forward only IPv4 packets to a Monitoring Services PIC.
IPv4 packets with MPLS labels cannot be forwarded to a Monitoring Services PIC.
By default, if packets with MPLS labels are forwarded to the Monitoring Services PIC,
they are discarded. To monitor packets with MPLS labels, you must remove the MPLS
labels as the packets arrive on the interface.
You can remove up to two MPLS labels from an incoming packet by including the
