Issue/Introduction
- The snmptd probe is not receiving traps from a device but is working for other traps.
- The traps do not even show up in the snmptd Trap Monitor.
Environment
- Release: UIM 8.x, 9.x, 20.x
- Component: UIM - SNMPTD
Cause
- The mib dependencies (dependent MIBs from the IMPORTS section of the main MIB) were not added to snmptd
Resolution
Most mibs depend upon other mibs which define calls made, and so must be loaded before the desired mib will work.
This is contained in the mib IMPORTS section of the mib.
For example:
IMPORTS
MODULE-IDENTITY,
OBJECT-IDENTITY,
enterprises
FROM SNMPv2-SMI;
In this case the mib requires SNMPv2-SMI.
Additional Information
In this example vnxe_alert.mib depends upon SNMPv3-SMI and SNMPv3-TC, so when the probe used vnxe_alert.mib it checks for SNMPv3-SMI and SNMPv3-TC, and if not found then it can't use vnxe_alert.mib.
