Product and Software: This article applies to all Aruba controllers running ArubaOS 5.x and later.
If the VIA client is configured to use a PSK, and if an IKE-PSK is not configured in controller, this message is displayed:
"ISAKMP stack could not be initialized"
To add the PSK using the webUI, go to Advanced Services > VPN and add the PSK.
To add the PSK using the CLI, issue this command:
(aruba) (config) #crypto isakmp key <pre-shared-key> address 0.0.0.0 netmask 0.0.0.0
