Cheats in Combat Trainng

Hi, I am Stu, I have a problem, I think most people have it, but I thought by now their might a be way to do it. What I am trying to do is use Cheats in Black ops Combat training, I know the command seta thereisacow "1337" but that allows the cheats but I still can't use them.

For example, if I bring down the console, and type in /god or /give all or anything else it says at the bottom, A mod is required to use this cheat.
If I remove the seta thereisacow "1337" it says as it normally would, Cheats are not enabled on this server. I find it strange cause these sort of hacks and cheats work in zombies and zombies online.
So if anyone knows where to get this mod, or a way to hack around it or anything like please tell me.

Very much Appreciated
