I am needing to download and use a file to parse through a list of MAC's (one per line) and add or remove based on the new file downloaded to the AP. I will have to step through the current access-list mac's and decide which ones need to be removed, then step through the new list of mac's and see which ones need to be added. Is this possible to complete in a script?

I can get the file downloaded to the AP, but have had no luck parsing through the file and pulling the mac's out to compare to the access-list. Any help would be much appreciated.

How do you see this process ?

It is possible to get current access-list configuration. Login to the router by ftp and download it to your computer.
Go trough that list and check all the MAC-addresses, add new MAC-addresses if you need.

Upload file back or even paste it to the console, apparently before you need to erase all access-list rules that were before.

I think the original poster wanted to do the other way - use "tool fetch" to get an export file, and to autmatically update access list. I think you can only make a script that will remove all entries, and will import the new ones.
