AP Interface Multicast Groups Joined

About this task

Multicast groups scale to a larger set of destinations by not requiring prior knowledge of who or how many destinations there are. Multicast devices uses their infrastructure efficiently by requiring the source to send a packet only once, even if delivered to a large number of devices. Devices replicate a packet to reach multiple receivers only when necessary.

Access Points are free to join or leave a multicast group at any time. There are no restrictions on the location or members in a multicast group. A host may be a member of more than one multicast group at any given time and does not have to belong to a group to send messages to members of a group.

To view the Access Point‘s multicast group memberships on the selected interface:
