I'm having a massive problem with my Cisco 851. I'm brand new to Cisco
and the IOS and will actually be attending some technical training in
the coming days. In the meantime, though, I am unable to use the built-
in firewall.

Using the SDM, here is the error I get when using the basic firewall
wizard:

-----------------------------------------------
Submitting 99 commands, please wait...
class-map type inspect match-any sdm-cls-insp-traffic


Error detected at this command. Click OK
-----------------------------------------------

When I connect to the router via the console, this is what it tells
me:

-----------------------------------------------
vorpalrouter#conf t
Enter configuration commands, one per line. End with CNTL/Z.
vorpalrouter(config)#class-map ?
% Unrecognized command
vorpalrouter(config)#class-map
-----------------------------------------------

Any idea why this is happening? Is there any other way I can lock down
ports?
