If the switch’s network interfaces to the TFTP server have gone down,
copy the core file to the nonvolatile file area before restarting the switch.
The following commands copy netsys.core.217.tar to the nonvolatile file
area and verify the result:
WX4400# copy core:netsys.core.217.tar file:netsys.core.217.tar
success: copy complete.
WX4400# dir

Debug Messages In addition to generating a core file, the switch also sends debug
messages to the serial console during a system crash. To capture the
messages, attach a PC to the port (if one is not already attached) and use
the terminal emulation application on the PC to capture a log of the
messages. (For information about connecting to the serial console port,
see the
Wireless LAN Switch and Controller Hardware Installation Guide ).
