NN47250-500 (320657-F Version 02.01)
In this example, the core file is netsys.core.217.tar. (The command_audit.cur file is not a core file and is created as part
of normal system operation.)
The following command copies the core file onto a TFTP server.
WSS# copy core:netsys.core.217.tar tftp://192.168.0.233/netsys.core.217.tar
...........success: sent 573440 bytes in 1.431 seconds [ 400726 bytes/sec]
success: copy complete.
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:
WSS# copy core:netsys.core.217.tar file:netsys.core.217.tar
success: copy complete.
WSS# 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 Nortel
WLAN—Security Switch 2300 Series Installation and Basic Configuration Guide.)
