Hierarchy Level


Enable qualified MAC learning on the third VLAN tag (innermost) of an ingress 3-tagged packet, without any kind of implicit VLAN manipulation. If the packet has 2 tags, MAC learning happens on the second VLAN. If the ingress packet has more than 3 tags, all tags beyond the third tag are treated as part of data and not considered for learning. For bidirectional traffic flow input-vlan-map pop must be configured.


In Junos OS Release 17.4R1 the vlan_tag_number is 3 only.
