Perform the following configuration in system view.

By default, the port aging time is 105 seconds. 

Use the commands in Table 312 to manually configure the maximum response time. 
If the Switch 5500 receives no report message from a port within the maximum 
response time, the switch will remove the port from the multicast group. 

Perform the following configuration in System View.

By default, the maximum response time is 10 seconds. 

Use the commands in Table 313 to manually set the aging time of the multicast group 
member port. If the switch receives no multicast group report message during the 
member port aging time, it will transmit the specific query message to that port and 
start a maximum response timer. 

Perform the following configuration in system view.

By default, the aging time of the multicast member is 260 seconds.

Normally, when receiving an IGMP Leave message, IGMP Snooping does not 
immediately remove the port from the multicast group, but sends a group-specific 
query message. If no response is received in a given period, it then removes the port 
from the multicast group.
