Yeah, the Packeteer has surprisingly limited function in that regard. Pretty much any other system works better. And it has a CLI interface that doesn't add any features.

The only advantage it has (and, IMO, this is pretty minor, though my IT Manager thinks it's wildly important) is that it will inspect and classify all passing data so that you can see what's been going through your network and easily add a new prioritization.

Edit: I take it back. It has one really neat hardware feature. It functions as an ethernet-to-ethernet bridge. It doesn't route. If the system reboots or loses power or in any other way isn't active, it still passes traffic. I don't know how it does that, honestly. An 8PDT normally-closed relay comes to mind.
