Configuring Port Aging Timers - H3C S3610 Series Operation Manual

Operation Manual – Multicast Protocol
H3C S3610&S5510 Series Ethernet Switches
Caution:
If you switch IGMP Snooping from version 3 to version 2, the system will clear all IGMP
Snooping forwarding entries for dynamic joins, and will:
Keep forwarding entries for version 3 static (*, G) joins;
Clear forwarding entries for version 3 static (S, G) joins, which will be restored when
IGMP Snooping is switched back to version 3.
For details about static joins, Refer to"Configuring Static Member Ports".

2.3.4 Configuring Port Aging Timers

If the switch does not receive an IGMP general query or a PIM hello message before
the aging timer of a router port expires, the switch deletes this port from the router port
list when the aging timer times out.
If the switch does not receive an IGMP report from a multicast group before the aging
timer of a member port expires, the switch deletes this port from the forwarding table for
that multicast group when the aging timers times out.
If multicast group memberships change frequently, you can set a relatively small value
for the member port aging timer, and vice versa.
