Using Option 43/60 for ZTP with Aruba IAP and isc-dhcpd

Hi Everyone,

I'm trying to get a isc-dhcpd to send the correct option43 and option 60 against a Aruba IAP however for some reason everything on the console get corrupted on the IAP when it get the messages from the DHCP and it does not get the full message. Does anyone have a working config for the IAP and with isc-dhcpd?

My config is below and i've tried both text and string in the code.


option space ArubaInstantAP;
option ArubaInstantAP.InstantAP60 code 60 = { string };
option ArubaInstantAP.InstantAP43 code 43 = { string };
option ArubaInstantAP.InstantAP42 code 42 = { string };
option local-encapsulation code 43 = encapsulate ArubaInstantAP;
option ArubaInstantAP.InstantAP43 "<Folder>,<Airwave-IP>,<Airwave-psk>";
option ArubaInstantAP.InstantAP60 "ArubaInstantAP";
option ArubaInstantAP.InstantAP42 "0.se.pool.ntp.org";


Thanks in advance

I have never deployed using isc-dhcp.  Do you have the console output?

 

Below is the console output for a successful Option43/60 deployment:

Have you seen the Instant Validated Reference Design guide chapter "Aruba Instant management using Aruba AirWave"?

The console output gets corrupted when the device gets all of the option43 message and when you run "show dhcpc-options" it does not show the correct thing.

Do you have an examplenconfig from when you did it?

I don't have screenshots of the windows server I used.  I used the example from the Instant Validated Reference Design document.  Do you know what version of Instant you are using?

Yes I used the design document, however ai think it's something with my linux dhcp-server (isc-dhcpd) and the lenght of the message in option 43.

I'll update with the version later

The version is 6.4.2.6-4.1.13, is there any bug in this release?
