<div> </div>

<div class="PlainText">Hi,<br>
<br>
<br>
I want to implement an option 43 string in the answer of the dhcp <br>
server. especially wand to implement Cisco openpnp as defined here: <br>
<a href="https://developer.cisco.com/site/open-plug-n-play/learn/learn-open-pnp-protocol/" data-auth="NotApplicable">https://developer.cisco.com/site/open-plug-n-play/learn/learn-open-pnp-protocol/</a>
<br>
<br>
<br>
<br>
The dhcp server should return the string "5A1N;K4;B3;I192.168.100.10".<br>
<br>
<br>
In ISC dhcpd the following config works:<br>
<br>
option space CISCOPNP;<br>
option CISCOPNP.pnpserver code 43 = string;<br>
class "ciscopnp" {<br>
match if option vendor-class-identifier = "ciscopnp";<br>
option vendor-class-identifier "ciscopnp";<br>
vendor-option-space CISCOPNP;<br>
option CISCOPNP.pnpserver = "5A1D;K4;B2;I192.168.100.10";<br>
}<br>
<br>
<br>
In kea I read a lot of doc, but I was not able to configure the server <br>
correctly.<br>
<br>
<br>
"Dhcp4": {<br>
"option-def": [<br>

}<br>
]<br>
(...)<br>
<br>
<br>
But the server does not return the option at all:<br>

<br>
<br>
Any idea what I am missing?<br>
