Web Registration Issue in NAC

[Mir_Ali]

I met similar issue with both EWC and NAC-GW (Identity Access Engine) sitting on the same vSwitch on the same VMware hosts. The communication from Qtrunk portgroup to non-qtrunkg portgroup was dropping packets heavily. this issue was fixed in new version of VMware.

good luck

Also, be sure that you have NAC ip addresses in the ip-helper addresses for the BYOD/guest vlan interface.

I'm not sure if this is the same problem BUT it's a good place to start. Verify the time on the NAC and your web controllers, make sure you have your SNTP set properly and there's no variation between all the devices.
