Since yesterday I have rogue qurier on the local network:

I 05/18/16 11:21:13 02418 igmp: AM2: VID 3: Start Querier role addr:
            10.172.250.1

10.172.250.1 is an ip address configured on the proper querier network switch.

I suspect that someone attached misconfigured switch to the network, but how can I track it down? There is nothing (ip/mac) about detected querier.

Is it possible to force querier IP address on other switches?

What do you get if you do a

show ip igmp vlan 3

?

HP5412R(config)# show ip igmp vlan 3

But it doesn't say which switch (except this) is set to be a querier too.

What happens if you issue that command after timing it to occur after the following has occurred on the switch:

I 05/18/16 11:04:58 02415 igmp: AM2: VID 3: Other Querier detected

Also,, same timing, run the command on another switch on your network.
