Description This article describes how to troubleshoot if a managed switch by FortiLink is losing config.
Scope Managed FortiSwitch.
Solution

The issue where FortiSwitch loses configs (For Ex: VLAN config, speed...etc) after reboot or periodically, verify if sthe witch is in config-sync error with FortiGate or not.

 

  1. Run the below command on FortiGate to check the sync-status:

 

execute switch-controller get-conn-status

 

  1. If all the switches are in synced state, check if config changes are made locally on the switch. The switch will loose local changes once it is synced with the FortiGate database. Therefore Local config changes are not recommended on the managed FortiSwitch.
  2. For troubleshooting, below debugs can be collected to check if configs are getting pushed to Switch from FortiGate or not:
  • On FortiGate start the below debug:

 

diagnose debug cli 8

diag debug enable

 

  • On FortiSwitch, start the below debug:

 

diagnose debug cli 8

diag debug enable

 

  1. Push the config from FortiGate and verify if switch debugs reflect any config reaching the FortiSwitch.
