Adding MAC Group Address
The device 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, relatin g to a sp ecifi c 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.
STEP 2 Enter the pa rameters.
•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
