Environment

NetIQ AppManager 6.x
NetIQ AppManager 7.0.x
SNMP Tookit Module for AppManager


Situation

Event: 'MIB Tree Reloading reported ASN.1 Parsing Errors' occurs when installing MIB files with AddMIBs script.
Installation of MIB files with the AddMIBs script.

Resolution

  • Many SNMP Agents accept MIB files with incorrect ASN.1 syntax.  This is especially true with proprietary vendor MIB files.  However, as a generic toolkit, the SNMP Module will report these syntax errors.  Depending on their severity, parts of the MIB may still successfully load.  Please report troublesome MIB files to NetIQ Support.  NetIQ may already be aware of a fix for the MIB file and can provide the updated MIB text.

    Someone familiar with SNMP MIBs may be able to edit the MIB text and correct the problem. An easy way to check MIB files before loading them onto the SNMP Proxy Agent is with the NET-SNMP tkmib browser.  Installations instructions are provided in the NET-SNMP.TXT file supplied with the module.  Note:  NetIQ, however, does not officially support tkmib.

    To check a set of MIB files for correct syntax:
    1. Copy the MIB files to be checked into the \usr\mibs directory.
    2. Change directory to \usr\mibs.
    3. Execute tkmib.bat.
    4. Two windows will appear: a DOS command prompt and the tkmib MIB Browser GUI.  Any parsing errors from the MIBs in \usr\mibs will be reported in the DOS command prompt.
  • Most MIB files have prerequisite MIBs that must also be loaded as part of a hierarchy.  Prerequisite MIBs are listed in the IMPORTS Clause near the beginning of every MIB file.  If a prerequisite MIB is not present, ASN.1 parsing errors will occur.

Cause

One or more prerequisite MIBs have not been installed.
