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?
