Enabling hardware failure protection for interfaces
After you enable hardware failure protection on an interface, the system automatically shuts down the interface when it detects a hardware failure on the interface. An interface shut down this way is in Protect Down state.
Before enabling hardware failure protection on an interface, make sure a backup link is available for uninterrupted services.
After the failure on an interface is removed, bring the interface up using the undo shutdown command.
To enable hardware failure protection for an interface:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Set the action to be taken in response to failures on the forwarding plane to isolate. | hardware-failure-detection forwarding isolate | By default, the system takes the action of warning (sending traps) in response to forwarding-plane failures. |
3. Enter Ethernet interface view. | interface interface-type interface-number | N/A |
4. Enable hardware failure protection for the interface. | hardware-failure-protection auto-down | By default, hardware failure protection is enabled. |
