The following table describes the related labels in this screen.

61.14  IGMP Filtering Profile

An IGMP filtering profile specifies a range of multicast groups that clients connected to the Switch are 
able to join. A profile contains a range of multicast IP addresses which you want clients to be able to 
join. Profiles are assigned to ports (in the 

IGMP Snooping

 screen). Clients connected to those ports are 

then able to join the multicast groups specified in the profile. Each port can be assigned a single profile. 
A profile can be assigned to multiple ports.

This saves your changes to the Switch’s run-time memory. The Switch loses these changes if it is 
turned off or loses power, so use the
