SNMP MIBs not loading in MIB trap browser

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

• Manufacturers MIB was added to probe as https://techdocs.broadcom.com/us/en/ca-enterprise-software/it-operations-management/ca-unified-infrastructure-management-probes/GA/monitoring/networking-infrastructure/snmptd-simple-network-management-protocol-trap-daemon-monitoring/snmptd-simple-network-management-protocol-trap-daemon-monitoring-release-notes.html
• All seems to be successful and MIB is seen in the  Nimsoft\Mibs Folder
• No traps are seen  for this MIB in the "MIB trap Browser"

Environment

Release: Any DX UIM

Component: snmptd probe any version

Cause

• The MIBs do not contain either the notification-group or notification-type entries which define the traps 
• The MIB Trap Browser reads the MIB and displays any traps it finds. 
• As there are none defined in the MIB it is not displayed in the MIB browser. 

Resolution

• The probe is working as expected. The only solution is to contact the vendor and request a MIB that contains notification-type and notification-group entries.  

Additional Information

Please also note that  TRAP-TYPE (or NOTIFICATION-TYPE in the MIBs will be visible in trap browser.
