When Troubleshooting a Wireless issue involving configuration, Radius Authentication, WPA, LDAP, AOS version, RF issues etc, the TAR LOG file is invaluable to solving issues and finding problems. The Tar Log file contains the Show Tech-support, Show run, and every possible log file generated by the Controller in one convenient zipped file.
You will need a TFTP server available to download the Log files once they are generated.
To generate a TAR.LOG run the follow CLI commands on the Powerconnect-wireless (Aruba) Controller:
1. (controller)# tar log tech-support -- This will generate the Log file, system management might hang for a bit but traffic will be unaffected
2. (controller)# dir -- this will show the files in the directory
3. (controller)# copy flash: logs.tar Tftp: 192.168.x.z logs.tar -- this will copy logs to tftp server
