2602e AP (Autonomous) - serial number file name in flash

[brandon.applegate]

Hello,

I have a 2602e autonomous running 15.3(3)JF12i.  In flash there is a file that is named the same as the PCB Serial Number as seen from "show ver".  I backup the config of this device using RANCID.  RANCID checks for diffs in config and archives a new version if something has changed.

Every once in a while this file will change modification time (and I assume contents).  RANCID sees this and pulls a new config unnecessarily.  

Anyone know what this file is ?  There is a minor version bump IOS I could put on here, but my gut tells me it won't change this. I can hack RANCID to ignore this - but I'd really like to know what it is as well.

Thanks.

Here's what is looks like:

ap#more flash:FOC12345LLK
00000000:  0000148C 14A0XXXX XXXXXXXX XXXXXXXX    .... . XX XXXX XXXX

No idea what it is/does but the timestamp seems to roughly correlate with last reload.

I just delete them when cleaning up the flash and never seen any adverse effect so far...
