Description

 

This article describes how to resolve a FortiAP showing as Offline/Down.

 

Scope

 

FortiGate, FortiAP.

 

Solution

 

When managed FortiAPs unexpectedly show as down, take the following steps:

 

Step 1: Check the system ARP and confirm all APs are receiving the IP.


 get sys arp

 

Step 2: Run the following debug command to check if the reason is N/A as in the example output below. '' to check down/failure reason if it is N/A as in the example output:

 

diagnose wireless-controller wlac -c wtp

image download progress: 0 
last failure : 8 -- Control message maximal retransmission limit reached 
last failure param: N/A
last failure time: Thurs Sep 08 12:18:46 2022

 

This command is generally used to diagnose or retrieve detailed information related to the Wireless Termination Points (essentially the managed access points) on the FortiGate device. The exact output would depend on the FortiOS version and the specific issues or configurations related to the WTPs. In general, it should provide insights into the status, configurations, or potential problems with the connected access points.

 

Step 3: Pick one IP from the ARP table and confirm connectivity through SSH to FortiAP from FortiGate CLI. 

 

execute ssh <user@host> [port]

 

Check the Interface and enable Fabric connection as it is a minimum management requirement that FortiAP establishes a CAPWAP tunnel with the FortiGate.

Since 6.2.0, the CAPWAP access has been grouped with the Security Fabric Connection. Before 6.0.x, an individual option was provided.

 

Follow these steps:

 

  1. Go to Network - > Interfaces. 
  2. Double-click the port. 
  3. Under Administrative Access, select Security Fabric Connection
  4. Select OK.
