Usage Guidelines

Usage Scenario

When the associated physical port is down after a CRC, SDH, receive, transmit, symbol alarm is generated on a port, the alarm cannot be recovered automatically. In that case, you can run this command to clear the alarm on the port. The port-alarm clear command clears alarms generated on a port and restores the port. The system does not save the configurations with this command. Therefore, configuration restoration is unnecessary.

Prerequisites

Run the port-alarm down (interface view) or port-alarm down (system view) command to enable the function of associating an error alarm with a physical interface Down event.

Precautions

This parameter is valid only when the related error alarm function is enabled. You can run the snmp-agent trap enable port command to enable the alarm function for CRC errors, SDH errors, receive errors, transmit errors, symbol errors on an interface.

Example

# Clear the crc-error alarm on the port and restore the updown status of the port.
