Multicast Listener Discovery | 611

Clear a specific group or all groups on an interface from the multicast routing table using the command 

 from EXEC Privilege mode.

Multicast packets are addressed with multicast MAC addresses, which represent a group of devices, rather 
than one unique device. Switches forward multicast frames out of all ports in a VLAN by default, even 
though there may be only some interested hosts, which is a waste of bandwidth. MLD Snooping enables 
switches to use information in MLD packets to generate a forwarding table that associates ports with 
multicast groups so that when they receive multicast frames, they can forward them only to interested 
receivers.

Display MLD groups. Group information 
can be filtered, see the FTOS Command Line 
Reference for the options available with this 
command.
