Re: NSLP Registry Question

Hi,

We have basically the following situation:

The QoS and NATFW NSLP share the error classes, but have different error codes. The other parameters are fine. 
(http://www.iana.org/assignments/nslp-parameters/nslp-parameters.xhtml#error-classes)

I did do a instruction write-up for this and send it to IANA but IANA requested better text - which I still need to provide.

IANA wants specific and clear instructions what to do with error codes.

Everything else is already fixed with IANA it is just to have a proper write-up of the IANA instructions.

I felt to clarify this.
