Configuring “Option 43” with those sub-options is an important exercise. If you use the isc-dhcp-server, the alternative to doing this in a decimal fashion yourself (which is error prone) is to use the “dhcp option space”.

Example:
#
# ALE Stellar Wireless option space
#

option space stellar;
option stellar.aleflag code 1 = text;
option stellar.proxyurl code 129 = text;
option stellar.proxyport code 130 = text;
option stellar.proxyuser code 131 = text;
option stellar.proxypass code 132 = text;

subnet 192.168.15.0 netmask 255.255.255.0 {
range 192.168.15.100 192.168.15.200;
option subnet-mask 255.255.255.0;
option routers 192.168.15.254;
option broadcast-address 192.168.15.255;
default-lease-time 6000;
max-lease-time 72000;
vendor-option-space stellar;
option stellar.aleflag “alenterprise”;
option stellar.proxyurl “URL=http://server.name”;
option stellar.proxyport “8080”;
option stellar.proxyuser “username”;
option stellar.proxypass “password”;
}

I assume that the formatting will not be really nice here, so kindly refer to this reference if the pasting doesn’t look good: https://dokuwiki.alu4u.com/doku.php?id=dhcp-settings-omnivista-cirrus

Standard Mandatory Requirements
Option 1 – Subnet Mask.
Option 2 – Gateway.
Option 6 – Domain Name Servers – Required for FQDN resolution of OmniVista Cirrus connection points.

Conditional Requirements:
Option 28 – Broadcast Address. This option is only recommended, not required.
Option 42 – NTP Server(s) – For Certificate validation (start date and duration), and all related encryption functions. This option is not required on devices running AOS 6.7.2 R04 / AOS 8.5R2 / AWOS 3.0.4 MR1 or higher. It is however recommended.
Option 43 : ALE custom option
The following sub-option 1 is only required on AOS devices running AOS 6.7.2 R03.
Sub-Option 1 – Vendor ID. To validate the DHCP response (alenterprise).

The following Sub-Options are only required if you are using a Proxy to connect to the Internet.
Sub-Option 129 – Proxy URL. It can be either an IP address or a URL (e.g., “IP-address=4.4.4.4”, “URL=http://server.name”).
Sub-Option 130 – Proxy Port.
Sub-Option 131 – Proxy User Name. If the customer proxy access requires authentication, both 131 and 132 can be supplied via these sub-options.
Sub-Option 132 – Proxy Password.
