<p>Hi Duane,</p>
<p>I'm using Kea 1.2 and I didnt have problem provisioning CMs and
CPEs on Our DOCSIS/HFC networks. I didnt need to disable Client-ID
on DHCP Offers packets. Write me on private if you like.</p>
<p>Kea docs are well documented, I suggest to check it again. <br>
</p>
I attach an simple and working example for provisioning CMs and CPES
in Kea 1.2 and dhcpdump capture (my Kea responses DHCP Client-ID
-option 61-)<br>

<p>We're evaluating KEA (version 1.2.0) as our DHCP platform
moving forward. In my testing with our Docsis/HFC network, I
am not able to have a docsis modem respond to a DHCPOFFER
message from KEA. I can get the same modem to respond to a
similarly formatted DHCPOFFER from ISC DHCP.</p>
<p><br>
</p>
<p>Looking at the tcpdump output from the server, the only
difference that stands out is the Client-ID (option 61).
While, in both cases, the docsis modem does supply the
Client-ID in the DHCPDISCOVER packet, the KEA server DOES
include the Client-ID in the resulting DHCPOFFER where the ISC
DHCP server DOES NOT include the Client-ID in it's DHCPOFFER.</p>

</p>
<p><br>
</p>
<p>I need to determine why the KEA offer is not 'working'.
Admittedly, I do not know for certain that the Client-ID is
the root of my problem. I think the next step is to somehow
prove that success or failure does indeed hinge on the
inclusion of the Client-ID field in the DHCPOFFER. I'm at
somewhat of an impasse, as I cannot figure out how to tell KEA
to NOT include the option. (At the same time, I cannot figure
out how to tell ISC DHCP to include the option - though this
is off topic for the Kea-users list.)</p>
<p><br>
</p>
<p>Does anyone have any insight into a configuration option to
disable option 61? Is there a generic way to disable a
certain option via the kea.conf file? Or, where in the code
can I 'flip the switch' the turn option 61 off on an offer?</p>
