Configuring hardware failure detection and
protection
Specifying the actions to be taken for hardware failures
The device automatically detects hardware failures on components, cards, and the forwarding plane.
You can specify the actions to be taken in response to detected failures.
To specify the actions to be taken in response to hardware failures:

in response to hardware failures.
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:
