If multicast group memberships change frequently, set a relatively small value for the dynamic member

port aging timer, and vice versa.

Configuring aging timers for dynamic ports globally

Follow these steps to configure aging timers for dynamic ports globally:

Configuring static ports

If all the 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, configure static

(*, G) or (S, G) joining on that port, namely configure the port as a group-specific or

source-and-group-specific static member port.

Configure a port of a switch to be a static router port, through which the switch can forward all the

multicast traffic it received.

Follow these steps to configure static ports:

To do... Use the command... Remarks

Enter system view

Required

Use either approach

Configure the port(s) as static

member port(s)

igmp-snooping static-group
