IV33250: INVALID OID REQUESTED WHEN INTERFACE FILTERING IS ENABLED AND ALL IN-SCOPE DEVICES ARE UNMANAGED AND REMANAGED

IBM Tivoli Network Manager IP 3.9.0 Fix Pack 4, 3.9.0-TIV-ITNMIP-FP0004
IBM Tivoli Network Manager IP Edition 3.9.0 Fix Pack 5, 3.9.0-TIV-ITNMIP-FP0005

APAR status

• Closed as program error.

Error description

• Product: Tivoli Network Manager
  Version: 3.8
  Component: poller
  
  
  Symptom:
  Enable SNMP polling and apply an interface filter.  The
  interface filter prevents the poller from simply walking the
  interface index and ensures that it has to construct the
  interface index as part of the poll.
  
  Select all the hosts that comprise the entire scope of the poll
  policy.  Then toggle the managed status of the devices, i.e.
  unmanage them all, and then remanage them all.
  
  
  This is a similar problem to APAR IV28101 in that the cause is
  down to the way an initial target is added when a poll policy
  has not been started and they way the first target is added
  again after all devices are re-managed.
  

Local fix

• Avoid selecting all the hosts within a poll policy and altering
  their managed state at one time.  Manage and unmanage hosts in
  smaller groups.

• ****************************************************************
  * USERS AFFECTED:                                              *
  * ITNM 3.8/3.9 poller users. Platform independent.             *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * Un-managing and re-managing all in-scope devices under a     *
  * SNMP Link state or SNMP threshold policy, which use          *
  * interface filtering, may trigger the raising of alerts       *
  * reporting NOSUCHNAME found for the monitored interfaces. In  *
  * the default product the symptoms are intermittent and may    *
  * not occur on every occasion or may only occur for a small    *
  * subset of interfaces.                                        *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * Suggest to upgrade to product version 3.8.0-ITNMIP-FP0007    *
  * and/or 3.9.0-ITNMIP-FP0004                                   *
  ****************************************************************
  

Problem conclusion

• The software has been updated such that SNMP Link state and
  Threshold poll policies configure the poller data structures
  with the appropriate data required to build the OIDs prior to
  starting the polling mechanism.
