All the Cisco SNMP MIBs are publicly available. If you have commercial SNMP management packets and/or shareware-freeware
packets, you may need to go and grab the MIB. Here is the FTP site:

By chance does anyone have a copy of a secure cisco config file? It's for
our
main company's main border router. I'm in serious need of something to
compare
mine too. I haven't been able to find a link too a good one.
If someone has a good link for reference I'd be so appreciative.

Thanks again,

Alexander
