Isolating and diagnosing a card
When the switch detects a card failure or upgrades the logic of the CPU daughter card on an interface
card, you can isolate the faulty card or the CPU daughter card to prevent it from forwarding data packets.
This operation allows for convenient on-site diagnosis or upgrading while causing no interference on the
operation of the system and services of other cards.
After isolating a card, you can use the test diag-offline command to collect the diagnosis information of
the card.
Configuration guidelines
•
When you upgrade the logic of an interface card, isolate the interface card first.
•
You can use the display device command to view whether a card is isolated, that is, whether the
card is in the offline state.
•
To minimize the interference on the system operation, H3C recommends that you force a network
interface card that is operating correctly offline before you remove it.
•
When you execute the test diag-offline command, the path where the diagnosis information is
saved is also displayed following the diagnosis information on the terminal. For example, you can
see flash:/diag_slot3_20080522_103458.txt.
•
H3C recommends that you send the diagnosis information to qualified engineers for analysis.
Configuration procedure
To isolate and diagnose a card:
Step Command Remarks
1.
Enter system view.
system-view
N/A
2.
Isolate a card.
•
In standalone mode:
board-offline slot slot-number
•
In IRF mode:
board-offline chassis
chassis-number slot slot-number
Use either command.
No card is isolated by default.
The active MPU cannot be isolated.
If only one switching fabric module
is working on the switch, it cannot
be isolated.
