command to document the switch and capture the output on a file.
3. Back up the switch configuration. Enter the Config Backup command to
back up the switch configuration to a file on the switch named configdata.
4. Back up the event log. Enter the Set Log Archive command to back up the
event log to a file on the switch named logfile.
5. Download the configuration and log files to your workstation. Open an FTP
session to download the configdata and logfile files onto your workstation.
