If you need to set cos on incoming packets (coming from a particular interface),  on the interface  you can apply a incoming classification policy map to set cos for all packets coming in.

This will apply the cos only to ppp control packets , not data packets.
To apply it to all packets you can set it on the interface or assign a policy to the users from radius.

Sniffing the traffic.
Or by applying a policy map with a class that matches  the cos value you are looking for, or several classes matching the various cos values you need.
Then see if counters match
