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:
Step
1. Enter system view.
2. Specify the action to be taken
in response to a type of
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:
Step
1. Enter system view.
2. Set the action to be taken in
response to failures on the
forwarding plane to isolate.
3. Enter Ethernet interface view.
4. Enable hardware failure
protection for the interface.

Enabling hardware failure protection for aggregation groups

After you enable hardware failure protection for aggregation groups, the system follows the following
rules when it detects a hardware failure on a member interface of an aggregation group:
Command
system-view
hardware-failure-detection
{ board | chip | forwarding } { off
| isolate | reset | warning }
Command
system-view
hardware-failure-detection
forwarding isolate
interface interface-type
interface-number
hardware-failure-protection
auto-down
191
Remarks
N/A
By default, the system takes the
action of warning (sending traps)
in response to hardware failures.
Remarks
N/A
By default, the system takes the
action of warning (sending traps)
in response to forwarding-plane
failures.
N/A
By default, hardware failure
protection is enabled.
