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.
