Description: The actions to be taken for a given layer 2 control protocol service frames that matches cevcSIL2ControlProtocolType, including:

'discard' The MEN must discard all ingress service frames carrying the layer 2 control protocol service frames on the EVC and the MEN must not generate any egress service frames carrying the layer 2 control protocol frames on the EVC.

'tunnel' Forward the layer 2 control protocol service frames with the MAC address changed as defined by the individual layer 2 control protocol. The EVC does not process the layer 2 protocol service frames. If a layer 2 control protocol service frame is to be tunneled, all the UNIs in the EVC must be configured to pass the layer 2 control protocol service frames to the EVC, cevcPortL2ControlProtocolAction column has the value of 'passToEvc' or 'peerAndPassToEvc'.

'forward' Forward the layer 2 conrol protocol service frames as data; similar to tunnel but layer 2 control protocol service frames are forwarded without changing the MAC address.
