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:
To do... Use the command... Remarks
Enter system view system-view —
Enter IGMP snooping view igmp-snooping —
Configure dynamic router port
aging time
router-aging-time interval
Optional
105 seconds by default
Configure dynamic member port
aging time
host-aging-time interval
Optional
260 seconds by default
Configuring aging timers for dynamic ports in a VLAN
Follow these steps to configure aging timers for dynamic ports in a VLAN:
To do... Use the command... Remarks

interval Optional
105 seconds by default
Configure dynamic member port
aging time igmp-snooping host-aging-time
interval Optional
260 seconds by default
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 system-view —

Enter Ethernet interface/Layer 2

Configure the port(s) as static
member port(s)
