I'm running 18.104.22.168 as default in production and wants wlc to boot with 22.214.171.124 if I run into issues regarding the 126.96.36.199.
To prepare I have predownloaded the backup image into all AP's.
However, if one AP reboots while the WLCis still running 188.8.131.52 the AP has an invalid primary image and need to re-download 184.108.40.206.
The backup image is then displayed as "220.127.116.11".
If someone reboots the AP, the reboot time is much longer than usually.
And the download might be an issue for some offices in Middle-East and Asia, since the WLC i located in Europe.
Due to some small VPN internet access lines.
This is something that came with version 18.104.22.168.
Before I upgraded the WLC, I was running 22.214.171.124 as primary and 126.96.36.199 as backup, with no issues regarding reboots and image.
Have anyone encounter this type of problem?
Any tips to solve this is much appreciated.
