specific cause or all causes. Use the no form of this command to disable the error-disabled detection
feature.
Syntax Description all

Command Default Detection is enabled for all causes.
Command Modes Global configuration
Command History Release

Usage Guidelines
A cause (all, dhcp-rate-limit, and so forth) is the reason why the error-disabled state occurred. When a
cause is detected on an interface, the interface is placed in an error-disabled state, an operational state
that is similar to a link-down state.
If you set a recovery mechanism for the cause by entering the errdisable recovery global configuration
command for the cause, the interface is brought out of the error-disabled state and allowed to retry the
operation when all causes have timed out. If you do not set a recovery mechanism, you must enter the
shutdown and then the no shutdown commands to manually recover an interface from the
error-disabled state.
