CpdV2L2PTDispType is a read-write setting on the configured flow (a per-EVC traffic instance rather than a whole physical facility) that selects how Layer 2 Protocol Tunnelling (L2PT) control frames (MAC 01:00:0C:CD:CD:D0) are disposed of when they reach this NE — typically processed locally, dropped, passed through untouched, or tunneled across the network via L2PT. Choosing the tunnel disposition here is what lets a provider transparently carry a customer's STP/CDP/VTP frames across the carrier core inside an L2PT-encapsulated wrapper instead of terminating them. On a flow carrying a particular customer's EVC across the network, an administrator would set this object to peer, drop, pass-through, or tunnel Layer 2 Protocol Tunnelling (L2PT) frames depending on whether this facility should terminate, block, forward, or L2PT-encapsulate that traffic.
