UFiber.Configurator [options]
Options:
--host <host> IP or hostname of the target UFiber device.
--host <host> IP or hostname of the target UFiber device. [default: 192.168.1.1]
--user <user> SSH user name. [default: ubnt]
--pw <pw> SSH password. [default: ubnt]
--port <port> SSH port of the target UFiber device. [default: 22]

--slid <slid> The SLID (or PLOAM Password).
--vendor <vendor> 4-digit Vendor Id (e.g. HWTC, MTSC, etc.). Combined with --serial, a GPON Serial Number is
built.
--serial <serial> 8-digit serial number (e.g. 01234567). Combined with --vendor, a GPON Serial Number is
built.
--serial <serial> 8-digit (e.g. 01234567) serial number or 16-digit (e.g. 41-4C-43-4C-xx-xx-xx-xx) HEX serial
number. Combined with --vendor, a GPON Serial Number is built. Note: If a 16-digit HEX
value is provided, the first 4 bytes (8 digits) will replace whatever value was passed to
Vendor Id with '--vendor'.
--mac <mac> The desired MAC address to clone.
