Troubleshooting Device Discovery Failure

 

Problem:

Description: Devices are not discovered to Junos Space Network Management Platform.

Symptoms: The devices you tried to discover to Junos Space Network Management Platform are not listed on the Device Management page.

The device discovery job for devices discovered through a device discovery profile, listed on the Job Management page fails.

Cause

You cannot discover devices to Junos Space Network Management Platform for one of the following reasons:

  • You provided an incorrect password to access the device through the Device Discovery Profile workflow.

  • You provided an incorrect private key or passphrase during the Device Discovery Profile workflow

  • The device is not reachable.

  • You provided incorrect SNMP settings for the device in the Device Discovery workflow.

Solution

  • If you entered an incorrect password, modify the device discovery profile by reentering the password and rediscover the device by using the Device Discovery Profile workflow.

  • If you uploaded an incorrect private key or passphrase, modify the device discovery profile by uploading the correct private key and passphrase and rediscover the device by using the Device Discovery Profile workflow.

  • If the device you are trying to discover is not reachable, add the correct route to the device. For more information about adding a route to the device, refer to the appropriate device configuration guide.

  • If you entered incorrect SNMP settings for the device, you can do one of the following:

    • Modify the device discovery profile by clearing the Use SNMP check box on the Network Management Platform > Devices > Device Discovery Profiles > Modify Device Discovery Profile > Specify Probes page and rediscover the device.

    • Modify the device discovery profile by adding the correct SNMP details on the Network Management Platform > Devices > Device Discovery Profiles > Modify Device Discovery Profile > Specify Probes page and rediscover the device.

      Note

      Ensure that SNMP is enabled on the device. For more information about enabling SNMP on the device, refer to the appropriate device configuration guide.
