REVISION "200402041200Z" -- 4 February 2004 12:00:00 GMT DESCRIPTION " Changes from as draft-pwe3-enet-mib-03: 1) Remove pwVcEnetFragSize and pwVcEnetCwStatus since they are controlled by the PW MIB module and they are duplicated here. 2) Change counter64 to ZeroBasedCounter32 in error Ethernet Pseudo Wire (PW) February 2004 Management Information Base statistics, and fix them to be read-only. " REVISION "200312161200Z" -- 16 December 2003 12:00:00 GMT DESCRIPTION " Changes from as draft-pwe3-enet-mib-02. 1) Module identity under the PW MIB tree. " REVISION "200307291200Z" -- 29 July 2003 12:00:00 GMT DESCRIPTION " Changes from as draft-pwe3-enet-mib-01. 1) Added Control Word status and fragmentation status. " REVISION "200209221200Z" -- 22 September 2002 12:00:00 GMT DESCRIPTION " Submitted 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 indicates that packet without a VLAN field (i.e. untagged frames) on the port are associated to this PW.
