Multicast
Multicast IP traffic is traffic that is destined to a host group. Host groups for IPv4 multicast are
identified by class D addresses, which range from 224.0.0.0 to 239.255.255.255. Host
groups for IPv6 multicast are identified by the prefix ff00::/8.
From the Multicast link, you can access the following screens:
• MFDB Table
• MFDB Statistics
• Auto-Video
• IGMP Snooping
• IGMP Snooping Querier
• MLD Snooping
MFDB Table
The Multicast Forwarding Database (MFDB) holds the port membership information for all
active multicast address entries. The key for an entry consists of a VLAN ID and MAC
address pair. Entries can contain data for more than one protocol.
To search the MFDB table:
1. Select Switching> Multicast > MFDB > MFDB Table.
2. Next to Search By MAC Address, specify the MAC Address whose MFDB table entry you
want to view.
Enter six two-digit hexadecimal numbers separated by colons, for example
00:01:23:43:45:67.
3. Click the Go button.
If the address exists, that entry will be displayed. An exact match is required.
The MFDB Table screen displays the information shown in the following table.
