The port-alarm down command enables the function for all interfaces on a subcard to shut down the associated physical port when an alarm is reported on an interface.
The undo port-alarm down command disables the function for all interfaces on a subcard to shut down the associated physical port when an alarm is reported on an interface.
By default, the function to shut down the associated physical port is disabled when an alarm is reported on an interface.
For NetEngine 8000 F1A, NetEngine 8000 F2A:
port-alarm down slot slot-id card cardid { crc-error | symbol-error | input-error | output-error }
undo port-alarm down slot slot-id card cardid { crc-error | symbol-error | input-error | output-error }
For NetEngine 8000 F1A:
port-alarm down slot slot-id card cardid sdh-error
undo port-alarm down slot slot-id card cardid sdh-error

Usage Scenario
This command can be used to shut down the associated physical port when an alarm of a certain type is reported to the NMS. The type of the alarm can be a CRC, SDH, input, output, symbol alarm.
You can run the port-alarm clear command to clear the alarms generated on a port and restore the port.Precautions
In VS mode, this command is supported only by the admin VS.
This command takes effect only when the corresponding alarm function is enabled. You can run the snmp-agent trap enable port command to enable the function to generate alarms for CRC, SDH, input, output, symbol errors on an interface.
