Issue/Introduction

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

Environment

Smarts - 10.1.x

TCSA - 2.x

Smarts-DM - 2.x

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.
