Usage Guidelines

Usage Scenario

The enable snmp trap updown command is used to enable an interface to send a Trap message to the NMS when the protocol status of the interface changes, which helps the NMS monitor the interface status in real time.

Precautions

By default, the function of sending a Trap message to the NMS when the protocol status of the interface changes is enabled. If an interface alternates between Up and Down, it will frequently send Trap messages to the NMS, causing the NMS to be busy processing these Trap messages. In this case, you can run the undo enable snmp trap updown command to disable the interface from sending trap messages to the NMS.

Example

# Disable an interface from sending a trap to the NMS when the protocol status of the interface changes.
