| Description | This object specifies the action to be taken for the given
layer 2 control protocol service frames which matches the
cevcPortL2ControlProtocolType, including:
'discard'
The port must discard all ingress service frames
carrying the layer 2 control protocol service
frames and the port must not generate any egress
service frames carrying the layer 2 control protocol
service frames. When this action is set at the port,
an EVC cannot process the layer 2 control protocol
service frames.
'peer'
The port must act as a peer, meaning it actively
participates with the Customer Equipment, in the
operation of the layer 2 control protocol service
frames. An example of this is port authentication
service at the UNI with 802.1x or enhanced link OAM
functionality by peering at the UNI with link OAM
(IEEE 802.3ah). When this action is set at the port,
an EVC cannot process the layer 2 control protocol
service frames.
'passToEvc'
The disposition of the service frames which are layer 2
control protocol service frames must be determined by
the layer 2 control protocol action attribute of the
EVC, (see cevcSIL2ControlProtocolAction for further
details).
'peerAndPassToEvc'
The layer 2 control protocol service frames will be
peered at the port and also passed to one or more EVCs
for tunneling. An example of this possibility is where
an 802.1x authentication frame is peered at the UNI for
UNI-based authentication, but also passed to a given
EVC for customer end-to-end authentication. |
