DESCRIPTION

 

Throttling

IGMP throttling controls how the Switch deals with the IGMP reports when the maximum

 

 

number of the IGMP groups a port can join is reached.

 

 

Select Deny to drop any new IGMP join report received on this port until an existing

 

 

multicast forwarding table entry is aged out.

 

 

Select Replace to replace an existing entry in the multicast forwarding table with the new

 

 

IGMP report(s) received on this port.

 

 

 

 

IGMP Filtering

Select the name of the IGMP filtering profile to use for this port. Otherwise, select

 

ProfileDefault to prohibit the port from joining any multicast group.

 

 

You can create IGMP filtering profiles in the Multicast > Multicast Setting > IGMP

 

 

Filtering Profile screen.

 

 

 

 

IGMP Querier

The Switch treats an IGMP query port as being connected to an IGMP multicast router (or

 

Mode

server). The Switch forwards IGMP join or leave packets to an IGMP query port.

 

 

Select Auto to have the Switch use the port as an IGMP query port if the port receives

 

 

IGMP query packets.

 

 

Select Fixed to have the Switch always use the port as an IGMP query port. Select this

 

 

when you connect an IGMP multicast server to the port.

 

 

Select Edge to stop the Switch from using the port as an IGMP query port. The Switch will

 

 

not keep any record of an IGMP router being connected to this port. The Switch does not

 

 

forward IGMP join or leave packets to this port.

 

 

 

 

Apply

Click Apply to save 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 Save link on the top navigation

 

 

panel to save your changes to the non-volatile memory when you are done configuring.

 

 

 

 

Cancel

Click Cancel to begin configuring this screen afresh.
