DHCP Option 119 - any guidance on this?
Good morning,
i need help on the implementation of DHCP Option 119 in Omada.
I've setup a small Omada-network with 3 VLANs and Domainnames. Unfortunately the DHCP-Server is not providing a field to enter the Domain searchlist. So i have to use the custom options. I've tried several days all aproaches i could find in the internet. The result was always the same, it didn't worked. I have assigned 1 of the 3 VLAN to only one port on a switch. On this port I've connected a Windows Notebook. Whatever i enter for Option 119 for the dedicated VLAN and click on save has the result that all DHCP Server stop working. After deleting the option and save it needs a little bit and all DHCP-Server are back working.
I checked RFC3397 and aligned on this. I calculated the domainsearchlist to Hex String and Array. I've also taken care of the correct compression outlined in another RFC. I've also achieved that the domainsearchlist was shown line by line after "ifconfig /all" on my Notebook. A ping and nslookup showed that it's also not working.
I searched a lot on the internet but didn't find any guide on how to implement this on Omada. Highly appreciate any input. I'm also open for different solutions. Is there a possibility for example to define searchlist on DNS-Server (local like CoreDNS)?
thank you
