SNMPUtil is just one method for checking connectivity, but these days I prefer to use
SNMPWalk or some other utility. I’m keeping this post here for archival purposes.
One of the first things you might want check while troubleshooting network device discovery in OpsMgr 2012 is to verify whether the network discovery server can connect to to the SNMP agent on the device. There are a few reasons why a network discovery server cannot connect to the device via SNMP, and one of the easiest methods to test this is to use a the

If the device is reachable via SNMP, you will receive a message similar to the following:
If the device is not reachable, you will receive a message similar to the following:
