WPAIE not found and required

[mtumanov123]

Can any body tell me what this dbeug output on 1100 means?

Sep 28 15:00:06.240: Client 0011.21ce.da30 failed: WPAIE not found and required

I believe this message means the client does not send out WPAIE in the association request.

This would seem to refer to a beacon information element specifying WPA parameters, as mentioned in these two documents:

Hope this helps.

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'

-add ssid on the radio by 'ssid '

-end

-wr mem

Ensure no shut on both devices' radios.

Done!

Hey!
I happen to see this issue in my lab
On non-root AP:
*Mar 27 03:10:39.930: 36B35A3D-1 Uplink: WPAIE not found and required

This was because the SSID config in the root didn't have the following line:
wpa-psk ascii PASSWORD

Once I added it to the root it worked fine, also make sure the SSID config matches on both ends (root non-root) and that the encryption is added in the radio interface.
Hope this helps :)
