Item Descri
tion
Aging Time 
Specify the aging time for multicast optimization entries. If the AP does not receive any 
IGMP report from a client within the aging time, the AP removes the client from the 
multicast optimization entry. 
Multicast 
Optimization Max 
Clients 
Specify the maximum number of clients supported by multicast optimization. 
If a client joins multiple multicast groups, the client is counted as multiple clients in 
multicast optimization statistics. For example, if a client has joined two multicast 
groups, the client is counted as two clients in the multicast optimization statistics. 
Max Client Limit 
Exceeded Action 
•  Pause Multicast Optimization for All Clients—Invalidate the multicast optimization 
function. A new client can join a multicast group and receive multicast packets, and 
a multicast optimization entry can be created for the client. However, the multicast 
optimization function for all clients in the multicast group becomes invalid. When 
the number of clients drops below the upper limit, the multicast optimization 
function takes effect again. 
•  Exclude New Clients for Multicast Optimization—Reject new clients. A new client 
can join a multicast group, but no new multicast optimization entries can be 
created. If multicast optimization entries have been created for other clients in the 
multicast group, the client cannot receive multicast packets. If not, the client can 
receive multicast packets. 
By default, the multicast optimization function becomes invalid when the maximum 
number of clients supported multicast optimization is reached.
