User Guidelines
The configuration parameters are not validated when this command is
entered. Use the write core test command to validate the configured
parameters and that the core dump is likely to succeed.
An average core file is around 450 KB. Example copy times are as follows:
• TFTP: 13mins (different subnet)
• USB: 3 mins
Administrators should ensure that a cleanly formatted USB flash drive of at
least 1G is used for collection of a the full core dump. Do not remove the USB
device during data transfer. Use the unmount command to cleanly detach the
USB device prior to physical removal.
Example
This example enables core dumps to a TFTP server 10.27.9.1 reachable over
the out-of-band port. The core file is written to the dumps directory and the
name includes the host name of the switch and the switch TOD.
