Thanks for your replies/help.

I set in the dictionary.f5 the following value :

ATTRIBUTE       F5-Acct                         14       string

First for the F5 NAS-IP-Address, it's equal to, which I suspect a
strange behavior of the F5 syslog-ng / audit forwarder. But this is not a
problem, I will find how to set it through tmsh or bigpipe shells.

Now, I have the correct output in F5-Acct attribute I've set in the

Thanks all for your help !

If you have any experience with F5 BigIP LTM/GTM accounting, please share
your feedbacks with me (in private of course).

For the specific VSA provided here, is it possible to add by default in
FreeRadius repo ?

This happens when an unknown attribute is found. The attribute is 
assumed to be type "octets" and is rendered at hex.

This won't help at all. This is ALREADY what FreeRADIUS assumes for 
unknown attributes.


ATTRIBUTE F5-Attr-14 14 string

...and see if it's readable.
