Issue/Introduction

The purpose of this article is to resolve the message / error when discovering various type of devices including UPS devices.

Environment

All supported Smarts versions

Cause

The error is usually displayed, because the agent determined that the packets timeliness was not within the threshold.

Resolution

• Try restarting the SNMPV3 agent. A restart of the SNMP V3 packet exchange will usually resolve the problem.
• If restarting the SNMP agent does not resolve it, try changing the SNMP timeout setting to 3000ms on the agent.
• Do another discovery to re-synchronize.
  
  Workaround:
  Updating the agent timeout setting to 3000ms and restarting the agent will usually resolve this issue
  
  

Note: This is not Smarts issue, recommendation suggested in this article to be discussed with the device owners / network administrators.

Additional Information

Discovery of the device will not be possible until the error is resolved.
