Technnical Tip: Reasons for FortiAP to show 'N/A' or '0' under the 'channel' column on managed FortiAPs

Description

This article describes the possible reasons for a FortiAP to show 'N/A' or '0' under the 'channel' column on managed FortiAPs.

Scope

FortiAP.

Solution

FortiAPs might show 'N/A' in the 'channel' column for one of the following reasons:

• There are no SSIDs configured for this radio.
  Solution: Configure at least one SSID on the radio.
  
  

• FortiAP is not properly energized; therefore, the radio is disabled.
  Solution: Check the PoE modes on the corresponding datasheet and energize the FortiAP accordingly.
  

PoE operation can be reviewed on the FortiAP with next command:

cw_diag power

• FortiAP has not reached its certification; it cannot use a channel in the current RF environment.
  Solution: Open a new ticket to the TAC team to further investigate and confirm whether the AP must be certified or not. Include the configuration file from FortiGate and the result of 'fap-tech' from FortiAP's CLI (via SSH or console port).
  
  

• Radio is in monitor mode.
  Solution: Configure the radio to work in Access-point mode.
  
  

• Radio is in the 'disable' state.
  Solution: Configure the radio to work in Access-point mode.
  
  

• FortiAP is offline on FortiGate.
  Solution: Check for possible issues on the CAPWAP tunnel. See this article: Troubleshooting Tip: FortiAP offline: Complete consolidated troubleshooting & checklist.
