FAQ | If one Q-SYS NS Series network switch is stacked/connected, does the IGMP Querier on all but one switch need to be manually disabled?

Learn how one Q-SYS NS Series network switch behaves when stacked/connected and whether or not you need to manually disable the IGMP Querier feature.

If you are linking or stacking multiple Q-SYS NS Series network switches they will all automatically participate in an election process and nominate one active IGMPv2 Querier for the network. This eliminates the need to manually change any switch configuration settings.


This is not guaranteed to work if there are other non-Q-SYS NS Series network switches on the network that also offer a
IGMPv2 Querier capability.
