Testing SNMP Traps with CDOT 8.2.1, OCUM 6.1, and MibBrowser: 3/3 - OCUM 6.1 + More

This post has been split into 3:

6: Sending SNMP Traps from OCUM 6.1 to TrapViewer

Note: The following step-by-step guide leads to a very simple test trap.

6.1: Login to NetApp OnCommand Unified Manager

If it’s gone, you should see this message:

6.5: Confirming the Trap was Received

Check to see if the trap has been received in TrapViewer:

7. How Many Defined SNMP Traps in the OCUM.mib and NETAPP.mib files?

Final section!

I thought this was a little bit interesting. The SNMP traps from the OCUM.mib are nicely located under the TRAPS part of the tree in the MibBrowser. The SNMP traps from the NETAPP.mib appear to be under Private > Enterprise > NetApp > NetApp-0.

From ManageEngine MibBrowser, you can copy all these traps out and paste them into a text file.

Count from NETAPP.mib = 205
Count from OCUM.mib = 279
