H3C S12508-AC Installation Manual page 84

To do...
Enable in-service hardware failure
detection and configure fix actions
taken in case of hardware failures
Enable hardware failure protection
for aggregation groups
Enter Ethernet interface view
Configure hardware failure
protection for the port
CAUTION:
Before configuring the hardware-failure-protection auto-down command on a port, make sure a backup
link exists to avoid service interruption in case the port is shut down.
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.
NOTE:
If a port is automatically shut down due to hardware failure protection, its status displayed with the
•
display interface command is Protect DOWN. To bring up the port, use the undo shutdown command
on the port.
• If a card is isolated or its software is not allowed to be loaded due to hardware failure fix operations,
you can plug out the card and then plug it in 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.
Use the command...
hardware-failure-detection { chip |
board | forwarding } { off |
warning | reset | isolate }
hardware-failure-protection

Remarks
Required
The fix actions taken in case of
hardware failures include the
following ones:
•
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 isolate.
Optional
Disabled by default
This command is effective only
when the fix action is configured as
isolate.
