Configuring IGMP snooping port functions
Before you configure IGMP snooping port functions, complete the following tasks:
• Enable IGMP snooping in the VLAN
• Configure the corresponding port groups
• Determine the aging time of dynamic router ports
• Determine the aging time of dynamic member ports
• Determine the multicast group and multicast source addresses
Configuring aging timers for dynamic ports
If the AC receives no IGMP general queries or PIM hello messages on a dynamic router port, it removes
the port from the router port list when the aging timer of the port expires.
If the AC receives no IGMP reports for a multicast group on a dynamic member port, it removes the port
from the outgoing port list of the forwarding table entry for that multicast group when the aging timer of
the port for that group expires.
If multicast group memberships change frequently, you can set a relatively small value for the aging timer
for the dynamic member ports, and vice versa.
Configuring aging timers for dynamic ports globally

3. Set the aging timer for
dynamic router ports.
router-aging-time interval 105 seconds by default
4. Set the aging timer for
dynamic member ports.
host-aging-time interval 260 seconds by default
