Configuring Static Multicast Ports - Nortel 2350 Reference Manual

204 Configuring WSS System Parameters
6
If IGMP queriers are not on the subnet (for example, multicast routers), select Querier Enabled.
Nortel recommends that you use the pseudo-querier only when the VLAN contains local multicast traffic
that is not routed.
7
In the Query Interval box, specify the interval (1 to 65,535 seconds) at which the WSS sends general
IGMP queries on behalf of multicast routers to advertise multicast groups. The default interval is
125 seconds.
8
In the Other Querier Present Interval box, specify how long (1 to 65,535 seconds) the WSS waits for a
general query to arrive before making itself the querier. The default interval is 255 seconds.
9
In 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).
10 In the Last Member Query Interval box, specify how long (1 to 65,535 tenths of a second) the WSS 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).
11 In 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.
12 To enable proxy reporting, which summarizes collected station IGMP reports, select Proxy Report.
13 To enable multicast router solicitation, which allows the WSS to discover multicast routers on the subnet,
select Multicast Router Solicitation.
14 In the Solicitation Interval box, specify the interval (1 to 65,535 seconds) between multicast router
solicitations by an WSS. The default interval is 30 seconds.
15 Click OK.

Configuring Static Multicast Ports

An WSS learns about multicast routers and receivers from multicast traffic received from those devices. When the WSS
receives traffic from a multicast router or receiver, the WSS adds the port that received the traffic as a multicast router or
receiver port. The WSS 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 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 WSS.
You can only add network ports as static multicast router ports or multicast receiver ports. Ports you add are immedi-
ately added to the list and do not age out.
Note.
You cannot add AP 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.
To add or remove static multicast router and receiver ports:
1
Access the VLAN table:
a
Select the Configuration tool bar option.
b
In the Organizer panel, click the plus sign next to the WSS.
