Yes, have assigned the static ip address for the VC. I suspect the all the IAP-105 coincidence can't find the VC then elect itself as a VC.
How to collect the logs from IAP? Through syslog? Because my customer doesn't syslog server ready.
Those IAP-105 not a VC, does it keep the IP address of the VC, right? Either power failure or reboot the IAP.
