Configuring Aging Timers For Dynamic Ports; Configuring Static Ports - 3Com 4500G Family Configuration Manual

Configure the corresponding port groups
Before configuring MLD Snooping port functions, prepare the following data:
Aging time of dynamic router ports,
Aging timer of dynamic member ports, and
IPv6 multicast group and IPv6 multicast source addresses

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 aging timers for dynamic ports globally
Follow these steps to configure aging timers for dynamic ports globally:
To do...
Enter system view
Enter MLD Snooping view
Configure dynamic router port
aging time
Configure dynamic member
port aging time
Configuring aging timers for dynamic ports in a VLAN
Follow these steps to configure aging timers for dynamic ports in a VLAN:
To do...
Enter system view
Enter VLAN view
Configure dynamic router port
aging time
Configure dynamic member
port aging time

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.
Use the command...
