Appendix A:Troubleshooting a WSS 789

Nortel WLAN—Security Switch 2300 Series Configuration Guide

The show tech-support command

The show tech-support command combines a group of show commands to provide an in-depth snapshot of the status of
the WSS. The output displays details about the system image and configuration used after the last reboot, the version,
ports, AAA settings, and other configuration values, and the last 100 log messages.
To save the output in a file to send to TAC, use the following syntax:

show tech-support [file [subdirname/]filename]

The following command saves the output in a file named fortechsupport and copies the file to a TFTP server.

WSS# show tech-support file fortechsupport

success: results saved to fortechsupport.gz

WSS# copy fortechsupport.gz tftp://192.168.0.233/fortechsupport.gz

success: sent 8259 bytes in 0.246 seconds [ 33573 bytes/sec]
success: copy complete.

Core files

If a WSS 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.
WSS# dir
