Validation Tests Reference
NetQ collects data that validates the health of your network fabric, devices, and interfaces. You can create and run validations with either the NetQ UI or the NetQ CLI. The number of checks and the type of checks are tailored to the particular protocol or element being validated.
Use the value in the Test Number column in the tables below with the NetQ CLI when you want to include or exclude specific tests with the netq check command. You can get the test numbers by running the netq show unit-tests command.
Addresses Validation Tests
The duplicate address detection tests look for duplicate IPv4 and IPv6 addresses assigned to interfaces across devices in the inventory. It also checks for duplicate /32 host routes in each VRF.

Agent Validation Tests
NetQ Agent validation looks for an agent status of rotten for each node in the network. A fresh status indicates the agent is running as expected. The agent sends a ‘heartbeat’ every 30 seconds, and if it does not send three consecutive heartbeats, its status changes to rotten.
