Hi Bret,<br>
<br>
The client-identifier is a DHCP option so you could use the<br>
flex-option hook to remove the option in certain situations. You can<br>
match on membership in a class, for example, if you can classify these<br>
clients in some way. Then use the remove mechanism of flex option to<br>
remove the dhcp-client-id (option 61) from the response. This KB<br>
article has an example of performing a similar action:<br>

> I’m migrating a site with about 11000 leases to kea and have found a small subnet (~200 devices) that don’t work if echo-client-id is true. Is there a more granular way to control this setting as I’d prefer to stick with current RFC defaults which then means
I need a second kea instance just for this small subnet of legacy devices. I could easily assign this subnet to a different client class, but I can’t see any way of controlling the echoing of client id at this level.<br>
