Hi all, Odd thing, a client's V2110 has a large amount of DHCPDiscover and DHCPOffer requests from it's interface. I am aware of this GTAC: https://extremeportal.force.com/ExtrArticleDetail?an=000077055 But is this the same ? Please see the attached screenshot from the log entry. It seems very excessive .. any thoughts ?

Hi Brendan, There is no interface configured as a DHCP server. This MAC is the closest to the interface on the controller itself. Let me explain: V2110 is a Hyper-V appliance. It is installed on a Clustered server. We tried to trace the MAC and do not see it anywhere. The closest we get (within 1 last octet) is the MAC of the controller's virtual NIC on the cluster. We checked all the MACs also, and could not see it on any server and virtual NIC. All we can see is that it is closely related to the same MAC, with 1 octet difference.

Do you have an interface configured on the V2110 as a DCHP server and do you know what device d4??52??22:9c is?
