The VLAN translation is applied in both ingress and
egress sides of all the Layer 2 trunks. It makes the
traffic arriving on the VLAN with this VLAN ID to
be mapped to or tagged with the corresponding instance
of cvtGlobalTranslatedVlan on the device. It also
causes all the traffic internally tagged with the
corresponding instance of cvtGlobalTranslatedVlan and
leaving the trunk ports to be tagged with the VLAN of
this VLAN ID.
