Vendor Specific Information (DHCP Option 43)

[boomer_sooner_88]

I need to know if I can configure Vendor Specific Informatiton (DHCP Option
43) on ISC DHCP.  Not sure exactly how to do this on ISC DHCP, but I can do
this without problem on Windows DHCP Server.

I need to convert "<a href="http://IPADDRESS:port/">http://IPADDRESS:port/" to Binary for the Option 43
Value.

Thanks!

Its pretty easy.

option space <some name>;
option <some name>.<some name 2> code <code #> = <data type>;
option <some name>.<some name 2> "<a href="http://IPADDRESS:port/">http://IPADDRESS:port/";

Here is a practical example from a Calix ACS URL (distribution of tr69 URL via DHCP):

option space CALIXGS;
option CALIXGS.acs-url code 1 = text;
option CALIXGS.acs-url "https://gcs14.calix.com:8443/123adskfjalskdf1/2kjakldfow";

HI boomer, 

this configuration is working for me. additional dhcp parameter request added on my side because my CPE was missing them while adding dhcp option 43. This may not required in your case. 

option space UMPSYS;
option UMPSYS.acs-url code 1 = text;
option UMPSYS.acs-PROVCODE code 2 = text;

option dhcp-parameter-request-list 60,43,3,6,15;
option vendor-class-identifier "dslforum.org";
vendor-option-space UMPSYS;
option UMPSYS.acs-url "http://IPADDRESS:port/";
option domain-name "yourdomain.com";

Note: no need of binary conversion for URL. 

regards, 

Usman Ahmad
