Configuring a static multicast MAC address entry in interface view
Follow these steps to configure static multicast MAC address entries in interface view
To do... Use the command... Remarks
Enter system view system-view —

Enter Ethernet interface/Layer 2

Required
In Ethernet interface view or Layer
2 aggregate interface view, the
configuration takes effect only on
the current interface, but in port
group view, the configuration
takes effect on all ports in the port
group.
Configure a static multicast MAC
address entry mac-address multicast mac-address
vlan vlan-id
Required
No static multicast MAC address
entries exist by default.
NOTE:
•
When you configure a static multicast MAC address entry in system view, the configuration is effective
for the specified interface. When you configure a static multicast MAC address entry in interface view or
port group view, the configuration is effective only for the current interface or interfaces in the current
port group.
• Any multicast MAC address except 0100-5Exx-xxxx—where x represents a hexadecimal number from
0 to F—can be manually added to the multicast MAC address table. A multicast MAC address is a MAC
address whose the least significant bit of the most significant octet is 1.
Configuring IGMP snooping port functions
Configuration prerequisites
Before you configure IGMP snooping port functions, complete the following tasks:
• Enable IGMP snooping in the VLAN
• Configure the corresponding port groups
• Determine the aging time of dynamic router ports
• Determine the aging time of dynamic member ports
• Determine the multicast group and multicast source addresses
Configuring aging timers for dynamic ports
If the switch receives no IGMP general queries or 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 IGMP reports for a multicast group on a dynamic member port, the switch
removes the port from the outgoing port list of the entry in the forwarding table for that multicast group
when the aging timer of the port for that group expires.
