Hi,
I want to implement an option 43 string in the answer of the dhcp
server. especially wand to implement Cisco openpnp as defined here:
https://developer.cisco.com/site/open-plug-n-play/learn/learn-open-pnp-protocol/
The dhcp server should return the string "5A1N;K4;B3;I192.168.100.10".
In ISC dhcpd the following config works:
option space CISCOPNP;
option CISCOPNP.pnpserver code 43 = string;
class "ciscopnp" {
match if option vendor-class-identifier = "ciscopnp";
option vendor-class-identifier "ciscopnp";
vendor-option-space CISCOPNP;
option CISCOPNP.pnpserver = "5A1D;K4;B2;I192.168.100.10";
}
In kea I read a lot of doc, but I was not able to configure the server
correctly.
"Dhcp4": {
"option-def": [
{
"name": "openpnp",
"code": 5,
"space": "vendor-encapsulated-options-space",
"type": "string",
"array": false,
"record-types": "",
"encapsulate": ""
}
]
(...)
subnet {
(...)
"reservations": [
{
"hw-address": "00:b8:b3:6b:69:c0",
"ip-address": "192.168.100.24",
"hostname": "staging01",
"option-data": [
{
"name": "openpnp",
"space": "vendor-encapsulated-options-space",
"code": 5,
"data": "5A1D;K4;B2;I192.168.100.10"
}
]
(...)
But the server does not return the option at all:

Any idea what I am missing?
