Rogue IGMP querier idetection.
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
I 05/18/16 11:20:09 02416 igmp: AM2: VID 3: Querier Election in progress, addr
10.172.250.1
I 05/18/16 11:15:47 02417 igmp: AM2: VID 3: End Querier role
I 05/18/16 11:15:47 02415 igmp: AM2: VID 3: Other Querier detected
I 05/18/16 11:10:23 02418 igmp: AM2: VID 3: Start Querier role addr:
10.172.250.1
I 05/18/16 11:09:19 02416 igmp: AM2: VID 3: Querier Election in progress, addr
10.172.250.1
I 05/18/16 11:04:58 02417 igmp: AM2: VID 3: End Querier role
I 05/18/16 11:04:58 02415 igmp: AM2: VID 3: Other Querier detected10.172.250.1 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?

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

Re: Rogue IGMP querier idetection.
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.
