User-side multicast maintenance includes checking multicast group joining information for online users and statistics about IGMP messages, and deleting statistics about IGMP messages on BAS interfaces.
If multicast group join information of a user is not needed, run the reset multicast group-ip command to delete it. After the command is run and then the user receives Query messages again, the device is triggered to restore the multicast group join information of the user.
To facilitate new IGMP message statistics lookup, you can run the reset igmp statistics command to delete existing IGMP message statistics on BAS interfaces if they are not needed.
