646CHAPTER A: TROUBLESHOOTING A WX SWITCH

Core Files If a WX switch restarts due to an error condition (crashes), the switch generates a core file in the temporary file area. The name of the file indicates the system area where the problem occurred. Core files are saved in tarball (tar) format.

Core files are erased when you restart the switch. You must copy the files to a TFTP server or to the nonvolatile part of file storage before restarting the switch.

To copy core files, use the dir command to list them, then use the copy command to copy them. The following example shows how to list the files and copy them to a TFTP server.

WX1200# dir

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.

WX1200# copy core:netsys.core.217.tar tftp://192.168.0.233/netsys.core.217.tar
