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.

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. 

Click Go. 

If the address exists, that entry will be displayed. An exact match is required.

The MFDB Table screen displays the following:

. The multicast MAC address for which you requested data.

. The VLAN ID to which the multicast MAC address is related.

. This is the component that is responsible for this entry in the Multicast 

Forwarding Database. Possible values are IGMP Snooping, GMRP, Static Filtering 
and MLD Snooping.

. This displays the type of the entry. Static entries are those that are configured 

by the end user. Dynamic entries are added to the table as a result of a learning 
process or protocol.

. The text description of this multicast table entry. Possible values are 

Management Configured, Network Configured and Network Assisted.

. The list of interfaces that are designated for forwarding (Fwd:) and filtering 

(Flt:) for the selected address.

. The resultant forwarding list is derived from combining all the 

forwarding interfaces and removing the interfaces that are listed as the static filtering 
interfaces.
