Hi all, I have a use case where one of the client class definitions should be applied for all subnets and my configuration has also been in the HA, so basically I need to assign two classes or sometimes I need to add more class statements to a subnet. So I tried configuring it like this and it didn't give me any syntax error Code snippet 1: =============== "subnet4": [{ "subnet": "4.0.0.0/24", "valid-lifetime": 86400, "option-data": [ { "data": "test.com", "name": "domain-name" }, { "data": "255.255.255.0", "name": "subnet-mask" }, { "data": "4.0.0.1", "name": "routers" } ], "pools": [{ "client-class": "allow-one,HA_dhcp1", "pool": "4.0.0.2-4.0.0.6" }], "id": 1 }], "client-classes": [ {"name": "deny-one"}, { "test": "(not(member('deny-one')))", "name": "allow-one" } ]
Basically, in the deny class statement, I will be adding my black-listing clients. I am able to start the kea-dhcp service with the above config file and the service is up and running but logically it seems to be wrong and I am facing issues while the lease flow, Later when I searched more for multiple class statements then I found like Code snippet 2: =============== "Dhcp4": { "client-classes": [{ "name": "phones", "test": "substring(option[60].hex,0,6) == 'Aastra'", }, { "name": "laptops", "test": "not member('phones')" }, { "name": "phones_server1", "test": "member('phones') and member('HA_server1')" }, { "name": "phones_server2", "test": "member('phones') and member('HA_server2')" }, { "name": "laptops_server1", "test": "member('laptops') and member('HA_server1')" }, { "name": "laptops_server2", "test": "member('laptops') and member('HA_server2')" }], Where we need to create one more class definition combined with the existing class, I want to know if code snippet 2 is the only way of dealing with the multiple client classes, I think code snippet 1 is also another way of dealing with the client classes because it is not giving any syntax error when I start kea-dhcp(Or I could be wrong to...) The problem is I have a use case where I have 5-6 client classes for some subnets and among these I will be using 2,3,4 for one subnet and 1,4,5 for another subnet likewise If I follow the second way of dealing with the multiple client classes the configuration would be much complex. In ISC-DHCP we just need one statement for the client class like allow members of client1; deny member of client2; ....some thing like this If anyone has familiarity with these concepts, much appreciate for your guidance or suggestion Thanks in advance Kraishak
