Parameter  Description 
Interface VLAN 
Enter the VLAN interface ID here. The range is from 1 to 4094. 
Designated Forwarding 
Select to enable or disable designated forwarding on a non-querier IGMP proxy 
downstream interface here. To avoid local loops and redundant traffic for links 
that are considered downstream links by multiple IGMP-based forwarders, IGMP 
proxies use the IGMP querier election to elect a single forwarder on a LAN. Use 
this option to make a non-querier device a forwarder. The feature does not take 
effect if the interface is not set as the downstream interface or set as the 
upstream interface.
