Greetings,
I have a subnet definition in my kea-dhcp6.conf, it inherited its configuration
from a client class called “device”, then I gave it some customization
configuration in the option-data section. After I used the config-write command
to get the config from memory, I noticed the client class of this subbed is no
longer “device” but “device_class2”, even I never defined this client class. My
guess is because of the customization data in option-data section, so kea
realized its configuration is different from the original client class
“device”, and it gives a new name.
Is this behavior expected? I think this could bring some troubles when we try
to do automatization. Now after we use the subnet hook, we have to use the
config-write command Darren mentioned to save the config changes from memory to
harddisk. And now in the new config file, we will have those “device_class2”
client class which previously didn’t exist.
Original config in kea-dhcp6.conf:
{
"id": 2,
"subnet": "2100:100:10:10::1/64",
"option-data": [
{
"space": "vendor-4491",
"name": "cores",
"code": 61,
"data": "2100:100:10:10::10-2100:100:10:10::100",
"always-send": true
}
],
"pools": [
{
"pool": "2100:100:10:10::10-2100:100:10:10::100"
}
],

"ip-addresses": [ "2100:100:10:10::1" ]
},
"interface": "ens2",
"client-class": “device",
"allocator": "iterative"
},
After using config-write:
