Configuring Mld Snooping Port Functions; Configuring Aging Timers For Dynamic Ports - 3Com S7906E Configuration Manual

To do...
Enter MLD snooping view
Configure the maximum
number of MLD snooping
entries
If the number of existing entries is larger than the limit when you configure it, the device informs you to
remove excessive entries. In this case, the device does not automatically remove any existing entries or
create new entries.

Configuring MLD Snooping Port Functions

Configuration Prerequisites
Before configuring MLD snooping port functions, complete the following tasks:
Enable MLD snooping in the VLAN
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.
