Troubleshooting Tip: Devices unexpectedly deleted from inventory view

Description

This article describes why devices modeled in a FortiNAC inventory may unexpectedly disappear.

Scope

FortiNAC v9.x, FortiNAC-F v7.x.

Solution

Example 1:

1. Switches A, B, and C are modeled in the Inventory.

2. Switch D is added.

3. Switch A is no longer listed in the Inventory.

Example 2 (FortiGate managed FortiSwitches):

FortiGate manages 16 FortiSwitches. However, the inventory only lists 12. The switches that appear in the list may change when a Resync Interfaces operation is run on the FortiGate.

Diagnose: From the CLI, list all network devices in Inventory and look for duplicate names.

FortiNAC-OS:

diagnose network device tree all | grep -i "Device:"

CentOS:

device -all | grep "*\*\*\*\*\*\*\*\* "

Names are listed between asterisks (*).

Ensure all switch names are unique. This is a requirement when adding devices to the Inventory. See the document: Add or modify a device.
