Error description

• ====================================================
  Severity: 2
  Approver: gdc
  Compid: 5724C04LN
  Release: 6.2.3
  
  Environment:
  The Monitoring Agent for Linux OS 6.2.3

  detect this status
  ====================================================
  

Local fix

• No Workaround
  

Problem summary

• The Linux OS agent does not detect a network interface status
  change due to a cable unplugged.
  
  
  The status of a network interface is reported by the Monitoring
  Agent for Linux OS in the Interface_Status attribute of the
  KLZ_Network group.  The status of a properly working Network
  Interface is indicated as UP.  When the network cable is
  unplugged the status is expected to become UP NOT RUNNING, but
  this is not occurring.  The status remains UP even if operating
  system commands like "ifconfig" or "ip addr" show it as no
  longer running.
  

Problem conclusion

• The status change is now being correctly detected and reported.
  
  The fix for this APAR will be contained in the following
  maintenance package:
