The following operations are performed when you use the VLAN mapping configuration:

•

Packets received on logical interfaces ge-1/0/0.1 , or ge-2/0/0.1, or ge-3/0/0.1, with a

single VLAN tag in the range from 1 through 1000 in the frame are accepted.

•

The VLAN tags of a received packet are compared with the normalized VLAN tags

specified with the vlan-id statement in the input VLAN map. If the VLAN tags of the

received packet are different from the normalized VLAN tags, then the received VLAN

tag is converted to the normalized VLAN tag of 1200 for packets received on the logical

interface ge-1/0/0.1. Similarly, for logical interface ge-2/0/0.1, the normalized VLAN
