Configuring Mld Snooping Port Functions; Configuration Prerequisites; Configuring Aging Timers For Dynamic Ports - HP A5500 SI Switch Series Configuration Manual

To do...
Enter Ethernet interface view,
Layer 2 aggregate interface view,
or port group view
Configure a static multicast MAC
address entry
NOTE:
For more information about the mac-address multicast command, see the
Reference.
The configuration that you make in system view is effective on the specified interfaces. The
configuration that you make in interface view or port group view is effective only on the current
interface or interfaces in the current port group.
Any legal IPv6 multicast MAC address except 3333-xxxx-xxxx—where x represents a hexadecimal
number from 0 to F—can be manually added to the MAC address table. A multicast MAC address is
a MAC address whose the least significant bit of the most significant octet is 1.

Configuring MLD snooping port functions

Configuration prerequisites

Before you configure MLD snooping port functions, complete the following tasks:
Enable MLD snooping in the VLAN
•
Configure the corresponding port groups
•
Determine the aging time of dynamic router ports
•
Determine the aging timer of dynamic member ports
•
Determine the 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, set a relatively small value for the aging timer of
the dynamic member ports.
Use the command...
interface interface-type interface-
number
mac-address multicast mac-address
vlan vlan-id
248
Remarks
Required
In Ethernet interface view or
Layer 2 aggregate interface
view, the configuration takes
effect on only the current
interface. In port group view, the
configuration takes effect on all
ports in the port group.
Required
No static multicast MAC address
entries exist by default.
