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.
Configuration procedure
To configure in-service hardware failure diagnosis and failure protection:
Step Command

}
Fix actions for hardware failures:
•
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
.
