Use the <code>Force</code> parameter only as a last resort to detach a network interface from a failed instance.

If you use the <code>Force</code> parameter to detach a network interface, you might not be able to attach a

If you force the detachment of a network interface, the <a

not get updated. This means that the attributes associated with the detached network interface might still be
visible. The instance metadata will get updated when you stop and start the instance.
