Configuring Aging Timers For Dynamic Ports - H3C S5500-EI Series Operation Manual

Operation Manual – Multicast
H3C S5500-EI Series Ethernet Switches
Enable IGMP Snooping in the VLAN or enable IGMP on the desired VLAN
interface
Configure the corresponding port groups.
Before configuring IGMP Snooping port functions, prepare the following data:
Aging time of router ports,
Aging timer of member ports, and
Multicast group and multicast source addresses

2.4.2 Configuring Aging Timers for Dynamic Ports

If the switch receives no IGMP general queries or PIM hello messages on a dynamic
router port, the switch removes the port from the router port list when the aging timer of
the port expires.
If the switch receives no IGMP reports for a multicast group on a dynamic member port,
the switch 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 member port aging timer, and vice versa.
