What is swIGMPProxyDownstreamVlanMemberPorts?
This read-only bitmap lists which ports on the downstream VLAN currently belong to a specific multicast group entry. An admin or monitoring tool can read this to see exactly which physical ports are actively receiving a given multicast stream, useful for verifying that the right subscribers are being served. Reading this for a channel group and seeing ports 3, 5, and 7 set would confirm those three ports currently have active viewers for that stream.
