Usage
Information
The line card core-dump is stored on flash in a directory:
• Storage Directory Name: flash:CORE_DUMP_DIR
— Line Card core-dump naming convention is: f10lpSlot_Number.core.gz
For example: f10lp6.core.gz
• Multiple core-dumps
— If multiple line cards crash, the core-dump files will upload simultaneously. However, a
second core-dump from the same line card slot will overwrite the first core-dump.
— During a line card core-dump, the line card interface remains up while the core-dump is being
written to the directory. Use the port-shutdown option to shutdown the physical interfaces
during the core dump, allowing for a failover to a backup system.
