[Kea-users] got unexpected keyword "valid-lifetime" in reservations map.

[Veronique Lefebure]

I don't know. You should probably test, or get the answer of an expert.

Hi Veronique,

So for a reservation entry, if we want to define a lease time that is different from subnet can we do as follows? i.e define only the option 51(dhcp-lease-time) will this be efficient ?
"subnet4": [
      {
         "subnet": "4.0.0.0/16<http://4.0.0.0/16>",
         "valid-lifetime": 3600,
         "reservations": [
            {
               "ip-address": "4.0.255.243",
               "hostname": "3G00034Phone",
               "valid-lifetime": 126,
               "hw-address": "aa:bb:cc:dd:ee:55",
               "option-data": [
                  {
                     "data": "126",
                     "name": "dhcp-lease-time"
                  },
                  {
                     "data": "4.0.0.1",
                     "name": "routers"
                  }
               ]
            }
         ],
         "option-data": [
            {
               "data": "test.com<http://test.com>",
               "name": "domain-name"
            },
            {
               "data": "255.255.0.0",
               "name": "subnet-mask"
            },
            {
               "data": "4.0.0.1",
               "name": "routers"
            }
         ],
         "pools": [
            {
               "pool": "4.0.0.2-4.0.0.202"
            }
         ],
         "id": 843191
      }
   ]

Thanks

Hi,
If you look at https://kea.readthedocs.io/en/latest/grammar/grammar.html you can see that valid_life_time is not an attribute of host-reservations:

Subject: [Kea-users] got unexpected keyword "valid-lifetime" in reservations map.

Hi All,

I am using the kea-dhcp of 2.2.0 version, I am trying to add a reservation entry along with a valid lifetime option value but I am facing the syntax issue saying "got unexpected keyword "valid-lifetime" in reservations map".

kea-dhcp4 -t kea-dhcp4.conf. --> syntax validator
Syntax check failed with:  kea-dhcp4.conf  :59.7-22: got unexpected keyword "valid-lifetime" in reservations map.

I took a sample example from the forums and tried as below:
"subnet4": [{
        "subnet": "4.0.0.0/16<http://4.0.0.0/16>",
        "valid-lifetime": 3600,
        "option-data": [
            {
                "data": "test.com<http://test.com>",
                "name": "domain-name"
            },
            {
                "data": "255.255.0.0",
                "name": "subnet-mask"
            },
            {
                "data": "99.99.99.99",
                "name": "routers"
            }
        ],
        "pools": [{
"pool": "4.0.0.2-4.0.0.202"
        }],
        "id": 843191
    }],
 "reservations": [
    {
      "hw-address": "01:23:45:67:89:ab",
      "ip-address": "4.0.0.223",
      "hostname": "example.com<http://example.com>",
      "valid-lifetime": 86400
    }
  ]

I tried moving the reservation section inside the subnet but still I get the same, Can someone who has familiarity with reservation entries can guide me ?


Thanks in advance
