Configuring In-Service Hardware Failure Diagnosis And Failure Protection - H3C S12500 Installation Manual

To do...
Locate the card problem for a
card on a specified member
switch (IRF mode)
CAUTION:
• The AMB cannot be isolated.
If only one switching fabric module is working on the switch, it cannot be isolated.
•
Before upgrading a logic of the line card, keep the line card offline.
•
• No other commands but the test diag-offline command can be executed for an isolated card.
Otherwise, the configuration cannot take effect.
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.
Use the command...

Remarks
Required
The fault detection information will be
displayed and saved in logs in the
root directory of the flash. Each log is
named in the format of
diag_slot_time, where slot indicates
the location of the card and time
indicates when the fault detection
operation is performed.
