I'm working on a lab using ExtremeConnect with VCenter and ExtremeControl.
The MAC auth is enabled on the EXOS switch (with XML-notification and IDMgr working fine). When the VM is authenticated, it shows all info correctly (ex: IP Address is resolved and shown) on ExtremeControl ES, but the OneFabric still updating the ES information and re-setting the VM IP address to null
The VMWare VM's are correctly auto-added to the Servers NAC ES Group.
In the following example, the 10.xx.xx.252 is the XMC Server and 10.xx.xx.251 is the ExtremeControl Appliance.
I've already tried to mess with the VMWARE module on Connect Configuration.
