REVISION "200209221200Z" -- 22 September 2002 12:00:00 GMT DESCRIPTION " Submited as draft-pwe3-enet-mib-00. Changes from previous version: 1) Alignment with draft-pwe3-ethernet-encap-00.txt: removing 'rangeVLAN' mode and the associated objects. 2) Relaxing requirement on value of pwVcEnetPortVlan in port mode. " REVISION "200208201200Z" -- 20 August 2002 12:00:00 GMT DESCRIPTION "Changes from previous version: 1) Add pwVcEnetVcIfIndex - Option for VC as ifIndex. 2) Change counters to 64 bits. 3) Add mode for adding/removing VLAN fields between PW and CE bound interface. 4) Referencing draft-martini instead of draft-so. 5) Editorial changes for some description clauses. 6) MPLS PRI mapping table to be independent (not augmented). 7) Adapt descriptions and rules of use to dratf-ietf-pwe3-Ethernet-encap-00.

It MUST be equal to pwVcEnetPwVlan if 'noChange' mode is used. The value 4096 indicate that no VLAN (i.e. untagged frames) on the port are associated to this VC.
