8In the Other Querier Present Interval box, specify how long (1 to 65,535 seconds) the WX switch waits for a general query to arrive before making itself the querier. The default interval is 255 seconds.

9In the Query Response Interval box, specify how long (1 to 65,535 tenths of a second) a device can take to respond to an IGMP query. The default interval is 100 tenths of a second (10 seconds).

10In the Last Member Query Interval box, specify how long (1 to 65,535 tenths of a second) the WX switch waits for a response to a group query, after receiving a leave message for that group, before removing the group. The default value is 10 tenths of a second (1 second).

11In the Robustness Value box, specify the robustness value (2 to 255), which sets IGMP timers to adjust to the amount of traffic loss on the network. Set the robustness value higher to adjust for more traffic loss. The default is 2.

12To enable proxy reporting, which summarizes collected station IGMP reports, select Proxy Report.

13To enable multicast router solicitation, which allows the WX to discover multicast routers on the subnet, select Multicast Router Solicitation.

14In the Solicitation Interval box, specify the interval (1 to 65,535 seconds) between multicast router solicitations by a WX. The default interval is 30 seconds.

15Click OK.

Configuring Static Multicast Ports

A WX learns about multicast routers and receivers from multicast traffic received from those devices. When the WX receives traffic from a multicast router or receiver, the WX adds the port that received the traffic as a multicast router or receiver port. The WX forwards traffic to multicast routers only on the multicast router ports and forwards traffic to multicast receivers only on the multicast receiver ports.

The router and receiver ports that the WX learns based on multicast traffic age out if they are unused. If necessary, you can statically configure multicast router ports or multicast receiver ports on the WX.

You can only add network ports as static multicast router ports or multicast receiver ports. Ports you add are immediately added to the list and do not age out.
