Usage Guidelines

Usage Scenario

The auto recovery function is configured and the delay for the transition from Down to Up is set on an interface using the error-down auto-recovery command. If the interface is now in the error-down state, run the display error-down recovery command to view the remaining time for an Up event.

An interface enters the error-down state after being shut down due to an error.

Prerequisites

The auto recovery function has been configured on an interface using the error-down auto-recovery command.

Configuration Impact

If interface is not configured in this command, the system displays information about all interfaces in the error-down state.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display the delay for the transition from Down to Up and the remaining time for the Up event.
