Q-Sys: Querier Address Configuration in Netgear M4250 Switches

Attention

Many users mistakenly interpret the Snooping Querier Address field as a pointer to the actual IGMP querier. This misconfiguration can lead to multiple switches announcing the same IP address, resulting in multicast traffic failures and network instability.

 

The Snooping Querier Address is the IP address a switch uses when acting as an IGMP querier, a role that manages multicast group memberships in a VLAN. It’s essential for enabling IGMP snooping, which ensures multicast traffic is only sent to ports where devices have requested it.
