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.

Information
This command is used for diagnostic purposes to isolate and identify a failed SFM when
troubleshooting issues related to the chassis dataplane.
When there are a full set of SFMs online, powering down one SFM will reduce the total bandwidth
supported by the chassis, and may affect data flow. A warning message is issued at the command line
that requires user confirmation to proceed with the command.
