“Value” in “Option: (t=43, l=29) Vendor-Specific Information” is the hexadecimal form of the URL
which is the path to download the config file. The Value is http://192.168.1.118/$mac.cfg.
PLANET terminal supports $mac replacement. The value of the URL can be
http://ip/$mac.cfg or
http://ip/mac.cfg?mac=$mac.cfg
“DHCP option 66” and “DHCP custom option” application parameters are similar to the DHCP option
43 above.
Note:
PLANET devices also support URL form of
http://ip/$input.cfg. If the “Value” in the above “Option: (t =
43, l = 29) Vendor-Specific Information” is
http://192.168.1.118/$input.cfg, the phone will pop up a dialog
box of inputting devices’ corresponding configuration ID values. The ID value is assigned by the
administrator. After entering the devices’ corresponding configuration ID values, the devices will
automatically download the config file of the corresponding ID from the server. PLANET devices support
$input replacement simultaneously. The value of the URL can be
http://ip/$input.cfg or
http://ip/input.cfg?input=$input.cfg.
Some HTTP/HTTPS/FTP servers require authentication of username and password, then PLANET
devices have two methods for this. Firstly, you can add username and password in the URL, for example,
http://username:passwd@ip/$mac.cfg. Secondly, for URL without username and password, the devices
will pop-up a dialog box to request user to enter username and password for authentication.
