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