DESCRIPTION

 

 

IGMP Querier

The switch treats an IGMP query port as being connected to an IGMP multicast

Mode

router (or server). The switch forwards IGMP join or leave packets to an IGMP

 

query port.

 

Select Auto to have the switch dynamically change to using the port as an IGMP

 

query port after it 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 back to the switch.

22.2.2 IGMP Filtering Profile

IGMP filter profiles allow you to control access to IGMP multicast groups. This allows you to have a service available to a specific IGMP multicast group. You can configure an IGMP filter profile for an IGMP multicast group that has access to a service (like a SIP server for example). Within a profile, configure an IGMP filter to specify the multicast IP address ranges. Then assign the IGMP filter profile to the ports (in the Multicast Setting screen) that are allowed to use the service.

Click Advanced Applications and Multicast in the navigation panel. Click the Multicast Setting link and then the IGMP Filtering Profile link to display the screen as shown.
