Configuring Igmp-Related Functions; Configuration Prerequisites - H3C S9500 Series Operation Manual

Operation Manual – IGMP Snooping
H3C S9500 Series Routing Switches
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 dynamic member port aging timer, and vice versa.
I. Configuring aging timers for dynamic ports globally
Follow these steps to configure aging timers for dynamic ports globally:
Enter system view
Enter IGMP Snooping
