Hello All,

i'm trying to configure Kea 1.5 to tie clients to their locations (because customers shouldn't move their equipment to any other location).

 My sample configuration is below:

   "client-classes": [
      "name": "opt82",
      "test": "relay4.[1].hex == 485754435096C50A",

  "subnet4": [
        "pools": [
              "pool":  " -",
              "client-class": "opt82"

And returning error is:
DHCP4_INIT_FAIL failed to initialize Kea server: configuration error using file '/usr/local/etc/kea/kea-dhcp4.conf': expression: [relay4[1].hex == 485754435096C50A] error: <string>:1.18-29: Invalid value in 485754435096. Allowed range: 0..4294967295 at (/usr/local/etc/kea/kea-dhcp4.conf: 15:11)

Question is:
    * how can i express the switch's circuit-id?


    * any other suggestion on solution?

Any reply would be appreciated,
Thank you
