Netgear “ACL is used by Class map or Interface” Error

Just posting this here since Google yielded no results. I was having trouble deleting access lists (for MAC authentication) on a Netgear GS752TP and was getting an error that said “ACL is used by Class map or Interface”. I thought it was because I had a MAC binding, but the MAC Binding Table had no entries. Turns out, I had some class-maps that didn’t clear and weren’t showing, for some reason or another, in the web interface.

The workaround is to go into MAC Binding Configuration and bind the ACL to the port, then unbind. How can you tell which ports are affected if they don’t show up in the web interface? Telnet to the switch and run show class-map

This will give you output with the ports that are binded.
