CpdV2GARPGroupDispType is a read-write setting on the configured flow (a per-EVC traffic instance rather than a whole physical facility) that selects how the combined GARP protocol group (GMRP and GVRP together) control frames (MAC range 01:80:C2:00:00:20-2F) are disposed of when they reach this NE — typically processed locally, dropped, passed through untouched, or tunneled across the network via L2PT. Because this is a coarse group-level control, changing it affects both multicast registration and VLAN registration behavior at once rather than one protocol at a time. This particular object is marked deprecated in favor of per-MAC-address disposition objects, but is retained for backward compatibility. On a flow carrying a particular customer's EVC across the network, an operator still on the legacy config would use this single knob to pass GMRP/GVRP frames through together rather than configuring each separately.
