-- Use these scripts to manage Cisco devices
name="BackupASA"
desc="Cisco Systems ASA SSH/TFTP Scripts"
protocol=TFTP

-----BEGIN SCRIPT "Configuration Upload"-----
enable
%ENABLEPSWD%
copy running-config tftp:
%TFTP_IP%

@receive 40
exit
-----END SCRIPT-----
-----BEGIN SUCCESS "Configuration Upload"-----

Put the script in your devicefiles directory on your NetSight server.
