Table 67 Advanced Application > Multicast > Multicast Setting (continued)

 

LABEL

DESCRIPTION

 

Fast Leave

Enter an IGMP fast leave timeout value (from 200 to 6,348,800) in

 

 

miliseconds. Select this option to have the Switch use this timeout to

 

 

update the forwarding table for the port.

 

 

This defines how many seconds the Switch waits for an IGMP report

 

 

before removing an IGMP snooping membership entry when an IGMP

 

 

leave message is received on this port from a host.

 

 

 

 

Group Limited

Select this option to limit the number of multicast groups this port is

 

 

allowed to join.

 

 

 

 

Max Group

Enter the number of multicast groups this port is allowed to join. Once a

 

Num.

port is registered in the specified number of multicast groups, any new

 

 

IGMP join report frame(s) is dropped on this port.

 

 

 

 

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.

 

Profile

Otherwise, select Default 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

 

Mode

multicast router (or 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.
