Re: Sep 28 15:00:06.240: Client 0011.21ce.da30 failed: WPAIE not found and required
When using Cisco AP and Cisco WGB/Universal Client, the above message indicates while both device's radios, eg 5GHz radio, have the correct SSID, there is a mismatch in encryptions on the radios. One device may have TKIP while the other device has AES encryption for the same SSID/radio.
To rectify the situation, eg, removing TKIP and adding AES on one radio, I suggest following sequential config steps:
-first disable SSID on the affected radio (eg, 5GHz radio per our example) interface of the device by 'no ssid '
-remove encryption by 'no encryption mode ciphers aes-ccm tkip'
-then, add encryption by 'encryption mode ciphers aes-ccm aes'
