Changing Robustness

Last member query interval — Number of tenths of a second that
the WX switch waits for a response to a group-specific query after
receiving a leave message for that group, before removing the receiver
that sent the leave message from the list of receivers for the group. If
there are no more receivers for the group, the switch also sends a
leave message for the group to multicast routers.
Robustness value — Number used as a multiplier to adjust the IGMP
timers to the amount of traffic loss that occurs on the network. Set
the robustness value higher to adjust for more traffic loss.
To change the IGMP query interval timer, use the following command:
set igmp qi seconds [vlan vlan-id]
For seconds, you can specify a value from 1 through 65,535. The default
is 125 seconds.
To change the other-querier-present interval, use the following
command:
set igmp oqi seconds [vlan vlan-id]
For seconds, you can specify a value from 1 through 65,535. The default
is 255 seconds.
To set the query response interval, use the following command:
set igmp qri tenth-seconds [vlan vlan-id]
You can specify a value from 1 through 65,535 tenths of a second. The
default is 100 tenths of a second (10 seconds).
To set the last member query interval, use the following command:
set igmp lmqi tenth-seconds [vlan vlan-id]
You can specify a value from 1 through 65,535 tenths of a second. The
default is 10 tenths of a second (1 second).
Robustness adjusts the IGMP timers to the amount of traffic loss that
occurs on the network. Set the robustness value higher to adjust for more
traffic loss. To change the robustness value, use the following command:
set igmp rv num [vlan vlan-id]
You can specify a value from 2 through 255. The default is 2.
