hi tam,
one can query an OID without having any MIB files installed ...
ohio> snmpget -c public test-rtr
.1.3.6.1.4.1.9.9.109.1.1.1.1.4.1
SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.4.1 = Gauge32: 11
ohio>
however, if one wants to query by object-value ... that's when one needs
MIB files installed. the MIB files permit the net-snmp utilities to
translate between that long string of numbers and something vaguely
human-readable:
guru> snmptranslate .1.3.6.1.4.1.9.9.109.1.1.1.1.4.1
CISCO-PROCESS-MIB::cpmCPUTotal1min.1
guru>
guru> snmpget -c public test-rtr cpmCPUTotal1min.1
CISCO-PROCESS-MIB::cpmCPUTotal1min.1 = Gauge32: 11
guru>
i'm guessing that either (a) you haven't yet copied the Cisco enterprise
MIB files to the appropriate location, or (b) you haen't yet modified
net-snmp's snmp.conf file to tell the net-snmp libraries to look at this
location.
i post some rudimentary install instructions around this -- how to install
enterprise MIB files (like Cisco's) and how to persuade the net-snmp
toolkit to use them -- at http://www.skendric.com/device/ that URL, and
http://www.skendric.com/trend/ also contain Perl code which queries
various Cisco-specific object-values ... you might find some of the
variables useful, if not the code itself.

How are you trying to retrieve the Cisco-specific information?
What commands are you giving?
