Hi Mathias,
I was just about to sent the exact same thing. 🙂
The problem I have with the substring is that I do not know if the substring will change (with a newer software update or whatever..)
as for you expression starting on 0 and a length of 6 will give me (in the currect string) 'geneos' but what gaurantees are there option 60 string will not change (to polar,geneos...xxxx., whatever)
until now I can make the expression by using split with the same limitations as mentioned above.
"test": "split(option[60].text, 0x2C, 2) == 'polar'",
Thanks for the insights.

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

Hi Mathias,
thanks for the quick reply.
Unfortunately this does not work
When I try your solution kea-dhcp does not start:
expression: [member('polar')] error: <string>:1.8-14: Not defined client class 'polar'

Hi Ronald,
I think you don't need the "VENDOR_CLASS_".
try with "test": "member('polar')"
Best Regards,

Hi all,
I am trying to identify on VENDOR_CLASS_ bu t seems not to be working..
This is what I tried so far:
kea-conf
(snippet)
"client-classes": [
{
"name": "Genexis",
"test": "member('VENDOR_CLASS_polar')",
Debug Log
DEBUG [kea-dhcp4.dhcp4/115727.139716649023040] DHCP4_CLASS_ASSIGNED [hwtype=1 58:00:32:31:34:f0], cid=[ff:00:01:00:01:00:03:00:01:58:00:32:31:34:f0], tid=0x7dba8a8d: client packet has been assigned to the following class(es): ALL, HA_dhcp2, VENDOR_CLASS_geneos-polar-3.13.1-R,polar,fibertwist-p2410,dslforum.org<http://dslforum.org/>, UNKNOWN
DEBUG [kea-dhcp4.eval/115727.139716649023040] EVAL_DEBUG_MEMBER Checking membership of 'VENDOR_CLASS_polar', pushing result 'false'
I was succesfull using this test:
"test": "split(option[60].text, 0x2C, 2) == 'polar'",
But I have no clue if 'polar' is always on the second value....
Any insights is appreciated.
Regards
