CpdV2CustomerLLDPDispType is a read-write setting on the Ethernet network-facing (NNI/trunk) port that selects how the LLDP Customer Bridge scope control frames are disposed of when they reach this NE — typically processed locally, dropped, passed through untouched, or tunneled across the network via L2PT. Setting this to pass-through lets a customer's own LLDP neighbor-discovery frames traverse the carrier facility end-to-end without the provider's own bridge intercepting them. On the network-facing trunk port linking to the next carrier NE, a carrier offering a transparent Ethernet private line would set this to pass-through so the two ends of a customer's LLDP session see each other unmodified.
