This article describes an issue on FortiOS v7.6.4 with a managed FortiSwitch where the switch name or configuration cannot be changed from the FortiGate GUI or CLI due to illegal characters being present in the switch name.
Scope
FortiOS v7.6.4.
Solution
In FortiOS v7.6.4, if a FortiLink managed switch-name contains an illegal character, it is not possible to rename the switch or change settings on that switch. This is often due to illegal characters having been present before upgrading to FortiOS v7.6.4.
Example of the issue:
config switch-controller managed-switch
(managed-switch) # edit Test.06
The legal allowed characters are numbers (0-9), letters(a-z,A-z) and special characters - and _ node_check_object fail! for switch-id Test.06
value parse error before 'Test.06' Command fail. Return code -651
FortiOS v7.6.5, v8.0.0 will allow an administrator to rename managed FortiSwitches that have illegal characters to a name without illegal characters.
Workaround:
Backup configuration file from the problematic device.
Rename the switch using only allowed characters:
Numbers: 0–9.
Letters: a–z, A–Z.
Special characters: '-' and '_'.
Restore the modified backup file. The configuration should now apply successfully.
