Changing the Router Solicitation Interval
The default multicast router solicitation interval is 30 seconds. To change the interval, use the following command:
set igmp mrsol mrsi seconds [vlan vlan-id]
You can specify 1 through 65,535 seconds. The default is 30 seconds.
Configuring Static Multicast Ports
An WSS switch learns about multicast routers and receivers from multicast traffic it receives from those devices. When
the WSS switch receives traffic from a multicast router or receiver, the switch adds the port that received the traffic as a
multicast router or receiver port. The WSS switch 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 WSS switch learns based on multicast traffic age out if they are unused.
You can add network ports as static multicast router ports or multicast receiver ports. Ports you add do not age out.
Note. You cannot add AP access ports or wired authentication ports as static multicast
ports. However, WSS Software can dynamically add these port types to the list of multicast
ports based on multicast traffic.
