HP 12500 Series User Manual

71
The hardware-failure-protection aggregation and hardware-failure-protection auto-down commands
do not take effect on an interface in the following cases:
• Loopback testing is enabled (using the loopback { external | internal } command).
• The interface is forcibly brought up (using the port up-mode command).
• The interface is a physical IRF port. For more information about physical IRF ports, see IRF
Configuration Guide.
An interface shut down for hardware failure protection is in Protect DOWN state. You can use the display
interface command to view the status. To restore the interface to UP state, execute the undo shutdown
command.
For a card that is isolated or forbidden to load software for hardware failure protection, you can remove
it and then reinstall it to restore it to operating state.
To view hardware failure detection and protection information, use the display
hardware-failure-detection command.
