Hello Richard,
CSM is different from other services module like FWSM or ACE, you actually don't need to access it to configure it
configuration and show commands are executed from C6500 supervisor CLI
module csm
and show commands starts with
show module csm ...
access to the module may be needed only for advanced troubleshooting under TAC direction
see

Hope to help
