Configuring static multicast MAC address entries
This feature is supported only on the router that is installed with the SAP module.
In Layer-2 multicast, a Layer 2 multicast protocol (such as IGMP snooping) can dynamically add multicast
MAC address entries. Multicast MAC address entries can also be manually configured.
Configuration guidelines
• When you configure a static multicast MAC address entry in system view, the configuration is
effective on the specified interfaces. When you configure a static multicast MAC address entry in
interface view or port group view, the configuration is effective only on the current interface or all
interfaces in the port group.
• Any legal 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. Multicast MAC
addresses are the MAC addresses whose the least significant bit of the most significant octet is 1.
