[Kea-users] KEA support for option 150 (tftp-server-ip)

[Gordon Ross]

Option 150 can be anything so you have to define it yourself.

//Define some custom options
    "option-def": [

    //Option for Cisco IP Phones to find CUCM.
    {
        "name": "cisco-cucm-servers",
        "code": 150,
        "type": "ipv4-address",
        "array": true
    }
]

Subject: [Kea-users] KEA support for option 150 (tftp-server-ip)
Hello,
In ISC DHCP v4.4.2 we have (https://downloads.isc.org/isc/dhcp/4.4.2/dhcp-4.4.2-RELNOTES<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdownloads.isc.org%2Fisc%2Fdhcp%2F4.4.2%2Fdhcp-4.4.2-RELNOTES&data=04%7C01%7Cgr306%40universityofcambridgecloud.onmicrosoft.com%7C3bf0cfae0b6e4bed9d9008d9d4e3efb1%7C49a50445bdfa4b79ade3547b4f3986e9%7C0%7C0%7C637774899185495933%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=vlNzPfz5%2B0C0vFxsPpCtcNTWNv9SMiiEoEPUqD0KmKM%3D&reserved=0>) :

Support for sending and receiving additional DHCP4 options has been added to both the dhcpd and dhclient. Specifically: option codes 93,94, and 97 (RFC 4578); code 150 (RFC 5859); and codes 209,219, and 211 (RFC 5071). Beyond configuring, sending, requesting, and receiving these options neither server nor client apply any additional logic based on their values. Thanks to Peter Lewis for requesting this change. [ISC-Bugs 47062]


In KEA, it seems that option 150 is not support.
We get this error:

 [Validation] Error encountered: definition for the option 'dhcp4.tftp-server-ip' having code '0' does not exist

Is there a solution or do we have to define that option ourselves?

Thanks,
Veronique
