Testing your SNMP Implementation
Testing NT Testing NetWare
If you have successfully installed SNMP on either NetWare or NT, and have added the performance NLMS (NetWare) or MIBS/DLLS (NT), then you are ready to see if you can actually access that information from your Network Management Station. WHAT?! You DON'T have a NMS? So NOW what are you going to do?
There are a couple of ways you can query the MIBS you have made accessible using SNMP4NT or SNMP4NW. One of them is getif, and the other is SNMPUTIL. This page discusses both, and provides sample strings for you to use to test your SNMP implementation.
Please see the Getif Page for detailed information! Newly expanded!
SNMPUTIL.EXE is a command line utility (included with the Windows NT 3.51 and 4.0 resource kits) that allows the querying of MIB information from a network device. While it supports GET/GETNEXT and WALK, I would hazard a guess that most peopleuse it to GET information and to WALK OID trees.
With the SNMPUTIL program, you can access the SNMP OID and get the information you want from a command line. The following image (showing a GET of the free memory on my Windows NT 4.0 system) is the SNMPUTIL equivalent of the getif MIB browse (free memory) on my Windows NT 4.0 system:
Download SNMPUTIL.EXE here. Save it in your %systemroot%\system32 directory. You can get SNMPUTIL.EXE as part of the Windows NT Resource Kit, or as part of SNMP4NT.Most of the SNMPUTIL command lines below should work, although depending on the OID "leaf" details, it may not return an accurate value. Remember, these are only to help you along with your testing. Each system will be a bit different, and, well, some of the OIDs may not return a value! Assume a target system IP of 127.0.0.1, with a community name of PUBLIC. Change to your values. Now, open a command prompt (start/run/cmd), and you are ready to play!
You can then "drill down" to the OID you need to access! Try it!
