Configuring Aging Timers for Dynamic Ports
If the switch receives no MLD general queries or IPv6 PIM hello messages on a dynamic router port, the
switch removes the port from the router port list when the aging timer of the port expires.
If the switch receives no MLD reports for an IPv6 multicast group on a dynamic member port, the switch
removes the port from the outgoing port list of the forwarding table entry for that IPv6 multicast group
when the port aging timer expires.
If IPv6 multicast group memberships change frequently, you can set a relatively small value for the
dynamic member port aging timer.

Configuring Static Ports
If all the hosts attached to a port is interested in the IPv6 multicast data addressed to a particular IPv6
multicast group, you can configure that port as a static member port for that IPv6 multicast group.
You can configure a port of a switch to be a static router port, through which the switch can forward all
IPv6 multicast data it received.
Follow these steps to configure static ports:
To do... Use the command... Remarks
Enter system view system-view —
Enter Ethernet interface view
