In order for your servers to respond to an SNMP request, there must be some 
sort of SNMP client to do the responding. The client uses MIB files to map data 
to OIDs. Now, it is possible the the OS has a built in client, I have not 
worked on the servers you mention and cannot say for sure.

One thing you can do is poll your servers to determine what data points are 
being exposed via SNMP. The following steps describe how to list all of these 
data points.

1. Most servers have SNMP Query configuration. Configure one of your servers 
with a community name and set the SNMP Query IP address to a Linux workstation. 
Give the IP address READ access.
2. Download all of the MIB files for your servers and software into a directory.
3. From the Linux workstation, CD to the directory with your MIB files and 
execute the snmpwalk command (part of the Net-SNMP package). I usually use the 
following syntax:

Code:
snmpwalk -v (SNMP version: 1 | 2c | 3) -c (community name) -m all -M +./ (IP 
address of server)


Example:

Code:
snmpwalk -v1 -c public -m all -M +./ 192.168.1.1


This will list the system OIDs. If you want to view the custom enterprise OIDs, 
try:

Code:
snmpwalk -v (1 | 2c | 3) -c (community name) -m all -M +./ (IP address) 
SNMPv2-SMI::enterprises 



You may get a lot of data back, so it may be helpful to redirect the output to 
a file and use an editor to review it. The above commands will use the MIBs to 
interpret the OIDs into textual identifiers, making them easier to read. If you 
see OIDs that are mostly numbers, you likely don't have the MIB file for that 
OID.
