Configuring In-Service Hardware Failure Diagnosis And Failure Protection - H3C S12508-AC Installation Manual

NOTE:
Use the display device command to view whether a card is isolated, or, whether the card is in the offline
•
state.
To minimize the interference on the system operation, force a switching fabric module that is operating
•
normally offline before you unplug it.
• When you execute the test diag-offline command, the path where the fault detection information is
saved is also displayed following the fault detection information on the terminal. For example, you can
see flash:/diag_slot3_20080522_103458.txt.
Deliver the fault detection information to the H3C technical engineers or engineers of the sales agent.

Configuring in-service hardware failure diagnosis
and failure protection
A hardware failure may cause traffic forwarding failures and service interruption. To improve the
automatic failure detection and handling capabilities of the switch, you can configure in-service
hardware failure diagnosis and failure protection.
The in-service hardware failure diagnosis and failure protection feature covers:
• In-service hardware failure detection for chips, cards, and the forwarding service, and automatic fix
actions taken for the detected failures.
Failure protection for ports: When a hardware failure is detected on a port, the switch automatically
•
shuts down the port.
Failure protection for aggregation groups. When a hardware failure is detected on a member port
•
of an aggregation group, if the member port is configured with the hardware-failure-protection
auto-down command, the port is shut down automatically; if the member port is not configured with
that command but it is not the last up port in the aggregation group, the port is also shut down
automatically; if the member port is not configured with that command and it is the last UP port in
the aggregation group, the port will not be shut down.
Follow these steps to configure in-service hardware failure diagnosis and failure protection:
