@Ghost-0 said in UniFi access points successfully adopt under ISC DHCP but won't adopt when KEA DHCP is enabled.:
I will read and try it
I've edited my post above.
A second, JSON text structure is also needed. It has to be 'defined' first :

{
"option-def": [
{
"name": "unifi",
"code": 1,
"space": "vendor-encapsulated-options-space",
"type": "string"
}
]
}
on the main

page.
Then, as said earlier, on every interface where you need the DHCP option 43, you have to put :
{
"option-data": [
{
"name": "vendor-encapsulated-options"
},
{
"name": "unifi",
"space": "vendor-encapsulated-options-space",
"csv-format": false,
"data": "C0A80109"
}
]
}
where "C0A80109" is hex for 192 168 1 9 => 192.168.1.9 if your controller uses 192.168.1.9 (an IP on my LAN network).
So you probably have to adapt that hex string.
The rest can be copied and places as-is.
That's in newbie range ^^
