[Kea-users] Identify on VENDOR_CLASS_

[Mathias Aichinger]

Hi,

I have just checked with my device. Genexis is sending it already with colons therefore the automatically created class would be " VENDOR_CLASS_geneos-polar-3.13.1-R,polar,fibertwist-p2410,dslforum.org <http://dslforum.org/>" which does not help you. 

I personally would use the substring function to extract geneos-polar without the version stuff as this is changing.

Unrelated example: "test": "substring(option[60].hex,0,6) == 'docsis'"

A newer fibertwist with the new software platform is sending this:
FiberTwist-P6426,GenXOS-Panda-GNX-11.8.0-R,dslforum.org <http://dslforum.org/>
So here I would extract "FiberTwist-P6426".

Best Regards,

Mathias
