IPMC Warning on Stack Slot 1 in specific VLAN

[MaWiFra]

Hello,

after I upgraded our whole Network Extreme components from 12.5.x to 15.3.1.4, I got the following IPMC Warning in the log and I don't know how to handle it:

"Date" "Time" Slot-1: Warning: received IGMPv1 query on vlan "VLAN_NAME" configured for IGMPv2 from "IP Address"
"Date" "Time" Slot-1: Previous message repeated 44 additional times in the last 7454 second(s)The strange thing is, that this message appears only on two Stacks in the DataCenter.

Anybody had/has the same problem and can help me to resolve/fix this message?

Thanks.

Did this ever get resolved? I am having similar issues.

Hi Nick, this error simply means that you have an IGMP mismatch between the sender of the IGMP packet (server/client) and the receiver (Switch). The versions must be compatible, or the switch must run a higher version than the client. So if the client is sending out IGMPv2, you can switch the Switch to either IGMPv2 or IGMPv3

i just repalced the original IP Adress, the IP is from the main core... So i can easily turn off the igmpv2 (sorry was a typing error) on the main core or is it better to exclude the Log entry?

Do wireshark capture and see from which source switch is receiving igmp v1 query. Turn it off . This message is just a warning included in 15.x we can also turn off warnings ... Log filter events exclude...
