• If a card is isolated or its software is not allowed to be loaded due to hardware failure fix operations,
you can remove the card and then install it to recover the card status.
• After configuring in-service diagnosis and failure protection, you can use the display
hardware-failure-detection command to check the running information of the feature.
Configuration procedure
To configure in-service hardware failure diagnosis and failure protection:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable in-service
hardware failure
detection and
configure fix actions
taken in case of
hardware failures..
hardware-failure-detection
{ chip | board | forwarding }
{ off | warning | reset | isolate }
The fix actions taken in case of hardware
failures include:
• off: Takes no action.
• warning: Sends warning messages.
• reset: Resets the failed card.
• isolate: Shuts down the failed port, isolates
the failed card, prohibits the failed card
from loaded, or powers off the failed card
to reduce the impact of the failure to the
system.
By default, the fix action taken for all
hardware failures is warning.
3. Enable hardware
failure protection for
aggregation groups.
hardware-failure-protection
aggregation
Optional.
Disabled by default.
This command is effective only when the fix
action is configured as isolate.
4. Enter Ethernet
interface view. interface interface-type
interface-number
N/A
5. Configure hardware
failure protection for
the port.
hardware-failure-protection
auto-down
Optional.
Enabled by default.
This command is effective only when the fix
action is configured as isolate.
The hardware-failure-protection aggregation and hardware-failure-protection auto-down command
do not take effect on a port in either of the following cases:
• The port is configured with the loopback { external | internal } command.
• The port is configured with the port up-mode command.
• The port is configured as an IRF physical port.
For information about IRF physical ports, see IRF Configuration Guide.
