CpdV2LANBridgesDispType is a read-write setting on the Ethernet network-facing (NNI/trunk) port that selects how IEEE 802.1d LAN Bridge Management control frames (MAC 01:80:C2:00:00:10) are disposed of when they reach this NE — typically processed locally, dropped, passed through untouched, or tunneled across the network via L2PT. This lets an operator decide whether legacy bridge-management frames from attached equipment are allowed to reach management systems or should be filtered at the edge. On the network-facing trunk port linking to the next carrier NE, an operator connecting to older 802.1d-only bridge equipment would set this so its bridge-management PDUs are not silently discarded.
