Usage Guidelines A cause (dtp-flap, link-flap, pagp-flap) is defined as the reason why the error-disabled state occurred.
When a cause is detected on an interface, the interface is placed in error-disabled state (an operational
state that is similar to link-down state).
You must enter the shutdown command and then the no shutdown command to recover an interface
manually from the error-disable state.
