When using the config switch fabric-channel trunk command to create a new trunk (or aggregate interface) or edit a trunk that has been previously added, the configuration change is implemented when you press the Enter key after entering the set command to change the configuration. Normally, in the FortiController CLI, configuration changes are not implemented until you enter end to save your changes. This also means that if you make a configuration change to a trunk and enter abort, the change has already been made and entering abort has no effect.

If you need to revert a trunk configuration change that you wanted to cancel with the abort command, you can use the config switch fabric-channel trunk command to manually revert to the correct configuration.

Changing the trunk (aggregate interface) configuration from the GUI is not affected by this issue. On the GUI, changes are not implemented until you select OK to save your changes and you can cancel a configuration change without saving it.
