Setting aging timers for dynamic ports

If a switch receives no IGMP general queries or PIM hello messages on a dynamic router port when the
aging timer of the port expires, the switch removes the port from the router port list.
If the switch receives no IGMP reports for a multicast group on a dynamic member port when the aging
timer of the port expires, the switch removes the port from the multicast forwarding entry for that multicast
group.
If the memberships of multicast groups change frequently, you can set a relatively small value for the
aging timer of the dynamic member ports. If the memberships of multicast groups change rarely, you can
set a relatively large value.
Configuring aging timers for dynamic ports globally
Step
1. Enter system view.
2. Enter IGMP-snooping view.
3. Set the aging timer for
dynamic router ports.
4. Set the aging timer for
dynamic member ports.
Configuring aging timers for dynamic ports in a VLAN
Step
1. Enter system view.
2. Enter VLAN view.
3. Set the aging timer for
dynamic router ports.
4. Set the aging timer for
dynamic member ports.

Configuring static ports

If all hosts attached to a port are interested in the multicast data addressed to a particular multicast group
or the multicast data that a particular multicast source sends to a particular group, you can configure the
port as a static member port for the specified multicast group or the specified multicast source and group.
You can also configure a port as a static router port, through which the switch can forward all the
multicast traffic that it received.
