Configuring Multicast Forwarding Adding MAC Group Address STEP 3 Click Apply. The Running Configuration file is updated. 15 Adding MAC Group Address The switch supports forwarding incoming Multicast traffic based on the Multicast group information. This information is derived from the IGMP/MLD packets received or as the result of manual configuration, and it is stored in the Multicast Forwarding Database (MFDB). When a frame is received from a VLAN that is configured to forward Multicast streams, based on MAC group addresses, and its destination address is a Layer 2 Multicast address, the frame is forwarded to all ports that are members of the MAC group address. The MAC Group Address page has the following functions: • Query and view information from the MFDB, relating to a specific VLAN ID or a specific MAC address group. This data is acquired either dynamically through IGMP/MLD snooping or statically by manual entry. • Add or delete static entries to the MFDB that provide static forwarding information, based on MAC destination addresses. • Display a list of all ports/LAGs that are a member of each VLAN ID and MAC address group, and enter whether traffic is forwarded to it or not. For viewing the forwarding information when the mode is IP Address Group or IP and Source Group, use the IP Multicast Group Address page. To define and view MAC Multicast groups: STEP 1 Click Multicast > MAC Group Address. The MAC Group Address page opens. STEP 2 Enter the parameters. • VLAN ID Equals To-Set the VLAN ID of the group to be displayed. • MAC Group Address Equals To-Set the MAC address of the Multicast group to be displayed. If no MAC Group Address is specified, the page displays all the MAC Group Addresses from the selected VLAN. STEP 3 Click Go, and the MAC Multicast group addresses are displayed in the lower block.
