This command displays the IGMP Snooping entries in the Multicast Forwarding Database 
(MFDB) table. 

A multicast MAC address for which the switch has forwarding and or filtering 
information. The format is two-digit hexadecimal numbers that are separated by 
colons, for example 01:23:45:67:89:AB. In an IVL system the MAC address 
will be displayed as a MAC address and VLAN ID combination of 8 bytes. 

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 pro-
cess or protocol.
