To set the IGMP timeout, enter a value between 30 and 300 seconds in the IGMP Timeout field. The
Step 7
controller sends three queries in one timeout value at an interval of timeout/3 to see if any clients exist
for a particular multicast group. If the controller does not receive a response through an IGMP report
from the client, the controller times out the client entry from the MGID table. When no clients are left
for a particular multicast group, the controller waits for the IGMP timeout value to expire and then
deletes the MGID entry from the controller. The controller always generates a general IGMP query (that
is, to destination address 224.0.0.1) and sends it on all WLANs with an MGID value of 1.
