Help :( with ca server

hi I recently purchased a ca server from nfo and I have no idea how to turn classes off. If anyone could help out I know the command was taken out I was curious if its a mod or a bunch of settings or what. Id really appreciate it. thanks.

seta g_ca_strong_ammo "10 15 20 25 75 100 10"
seta g_ca_weak_ammo "0 15 15 50 75 120 10"
seta g_ca_weapons "16383 1535 8959 6399"

maybe ?
