Using VLAN Tags in Maps

Ingress port VLAN tags are supported in first level maps, including the following:

■   map
■   map-passall
■   map-scollector
■   GigaSMART operation (gsop-enabled) maps

For example, if the traffic from network port 2/1/q3, (which has VLAN tag 1001 configured), is forwarded to tool port 2/1/q4. The traffic at tool port 2/1/q4 will have the added VLAN tag 1001. (Even though the VLAN tag is configured on the network port, it is added when the traffic exits the tool port.)

Note:  Traffic from a network port will not match a map rule that filters on a VLAN tag configured on the network port.
