Indicate the mode of VLAN handling between the port
associated to the VC and the VC encapsulation itself.
- 'other' indicate operation that is not defined by
this MIB.
- 'portBased' indicates that the forwarder will forward
packets between the port and the PW independent of their
structure.
- 'noChange' indicates that the VC contains the original
user VLAN, as specified in cpwVcEnetPortVlan.
- 'changeVlan' indicates that the VLAN field on the VC
may be different than the VLAN field on the user's
port.
- 'removeVlan' indicates that the encapsulation on the
VC does not include the original VLAN field. Note
that PRI bits transparency is lost in this case.
- 'addVlan' indicate that a VLAN field will be added
on the PSN bound direction. cpwVcEnetPwVlan indicate
the value that will be added.
- 'removeVlan', 'addVlan' and 'changeVlan' implementation
is not required.
