All access points (APs) under my C9800-80 controller are operating in local mode. I have two different SSIDs: one with WPA2 Enterprise and the other with open (central web authentication with ISE). There doesn’t appear to be a general issue, everything seems okay. However, I am receiving the log message "RSN ERROR: Received a data frame when no keys are plumbed" on the APs.
What could be the cause of this error? Is there a misconfiguration on my part? Does this error negatively impact the users?
