Hello.
I have defined domain name server option in subnets configuration.
I need to override dns servers for a part of clients.
These clients was separated by option 60.
I created client class with matching by option 60.
In client class I have defined other dns servers.
In logs I see that client was matched to my client class but client receives
dns from subnet config, not from client class config.
This means that subnet options have higher priority than client class?
If options defined in subnets remains, how can I override them with client
class? Is there a way to create client class with higher priority?
Config:
"Dhcp4": {
"client-classes":
[
{
"name": "ClinetsSec",
"test": "option[60].hex == 0x736563646E73",
"option-data":
[
{
"name": "domain-name-servers",
"code": 6,
"space": "dhcp4",
"csv-format": true,
"data": "192.168.30.21,192.168.30.22"
}
]
}
],
...
Backend config...
Shared network and subnet in it created with api
curl -X POST -H "Content-Type: application/json" -d '{"command":
"remote-network4-set","arguments":{"shared-networks": [{"name":
"TestShared"}],"remote": {"type": "mysql"},"server-tags": [ "all" ]},
"service": [ "dhcp4" ]}' http://127.0.0.1:8000/
curl -X POST -H "Content-Type: application/json" -d '{"command":
"remote-subnet4-set","arguments":{"subnets": [{"id": 2,"subnet":
"192.168.0.0/24<http://192.168.0.0/24>","shared-network-name":
"TestShared","pools": [ { "pool": "192.168.0.50-192.168.0.254" }
],"rebind-timer":18900,"renew-timer":10800,"valid-lifetime":21600,"option-data":
[ {"name": "routers","data":
"192.168.0.12"},{"name":"domain-name-servers","data":"8.8.8.8,8.8.4.4"}]}],"remote":
{"type": "mysql"},"server-tags": [ "all" ]}, "service": [ "dhcp4" ]}'
http://127.0.0.1:8000/
I see in logs that client matched to class ALL, unknown, VENDOR...and ClinetsSec
But dns servers in offer are not from client class, they are from pool config
