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.
