No interfaces are found in Network Discovery

Overview

This article discusses the issue where no interfaces are found in Network Discovery that was expected to have devices with active interfaces.

Environment

All NPM versions

Cause

This can occur because of one or more of the following reasons:

  • The SNMP credentials for the devices were incorrect.
  • The Ignore nodes that only respond to ICMP (ping) option under Network Discovery > Discovery Settings view is not selected, and the devices discovered are ICMP-only with no interfaces.
  • The nodes discovered do not currently have any actively operational interfaces.

Resolution

  1. Verify the following:
    • The discovery criteria do not exclude the devices on which you expect to find interfaces.
    • All interfaces are fully operational.
  2. Re-run Network Discovery.
