[Kea-users] subclass handling in kea-dhcp

[Kraishak Mahtha]

Thanks, Darren Ankney, and Veronique Lefebure for the information and for
sharing the sample example
and Francis Dupont for the information.

I am able to achieve my requirement now by
"client-classes": [
  {
    "name": "denyClients",
        "test": "hexstring(pkt4.mac, ':') == '11:22:33:44:ab:66' or
hexstring(pkt4.mac, ':') == '3f:ff:ff:00:00:01' "
  },
  {
    "name": "allowClients",
    "test": "(not(member('denyClients')))"
 }
]3f:ff:ff:00:00:01

pools": [
  {
    "pool": “12.3.0.0-12.3.0.254",
    "client-class": "allowClients"
.......

Thanks
Kraishak
