Cisco WAP forgets schedule after power loss

Last Modified: 2014-05-06
Hello everyone, I have a number of Cisco access points throughout the company running in standalone mode. The one in question is an AIR-AP1041N which has performed just fine save for one thing; after a power loss it forgets the latest change to the time-range (schedule) I've programmed it with and reverts back to its original schedule.

I don't believe there's anything wrong with the access point as it holds on to the rest of the configuration, it must just be something I'm doing wrong with altering the time-range.

I'm working at the CL because as far as I know I cannot create a time-based ACL through the GUI. My usual workflow is to create a time-range, create the ACL using said time-range, apply the ACL to a network interface. This all works great, but where things break down is when there is a change to the time-range. Originally I was just altering the time-range but during normal operation it would randomly forget my changes and revert back to the original. I eventually clued in that if I remove the time-range as well as the ACL that uses it, then recreate them both it would keep the changes indefinitely... that is until we had a power outage and again my changes were lost. Further testing showed that power cycling the device would consistently undo my changes.

What am I missing, any suggestions on why these changes are not permanent?

BTW I've also included this post in the Routers and Firewalls categories as I'm sure that someone will be using a time-based ACL on a Cisco device in those categories as well.
