If a dynamic router port receives an IPv6 PIMv2 hello message, the aging timer for the port is
specified by the hello message. In this case, the
mld-snooping router-aging-time
command
does not take effect on the port.
•
MLD multicast-address-specific queries originated by the Layer 2 device trigger the adjustment
of aging timers of dynamic member ports. If a dynamic member port receives such a query, its
aging timer is set to twice the MLD last listener query interval. For more information about
setting the MLD last listener query interval on the Layer 2 device, see "Setting the MLD last
listener query interval."
•
You can set the timers globally for all VLANs in MLD-snooping view or for a VLAN in VLAN view.
For a VLAN, the VLAN-specific configuration takes priority over the global configuration.

Configuring static ports
You can configure the following types of static ports:
•
Static member port—
When you configure a port as a static member port for an IPv6 multicast
group, all hosts attached to the port will receive IPv6 multicast data for the group.
The static member port does not respond to MLD queries. When you complete or cancel this
configuration, the port does not send an unsolicited report or done message.
•
Static router port
—When you configure a port as a static router port for an IPv6 multicast
group, all IPv6 multicast data for the group received on the port will be forwarded.
To configure static ports:
