Subject: [L2sm] [Editorial Errata Reported] RFC8466 (6683)

The following errata report has been submitted for RFC8466, "A YANG Data Model for Layer 2 Virtual Private Network (L2VPN) Service Delivery".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid6683

--------------------------------------
Type: Editorial
Reported by: Mohamed Boucadair <[email-masked]>

Section: 5.10.2.1

Original Text
-------------
   QoS classification rules are handled by "qos-classification-policy".
   qos-classification-policy is an ordered list of rules that match a
   flow or application and set the appropriate target CoS
   (target-class-id).  The user can define the match using a
   more specific flow definition (based on Layer 2 source and
   destination MAC addresses, cos, dscp, cos-id, color-id, etc.).  A
   "color-id" will be assigned to a service frame to identify its QoS
   profile conformance.  A service frame is "green" if it is conformant
   with the "committed" rate of the bandwidth profile.  A service frame
   is "yellow" if it exceeds the "committed" rate but is conformant with
   the "excess" rate of the bandwidth profile.  Finally, a service frame
   is "red" if it is conformant with neither the "committed" rate nor
   the "excess" rate of the bandwidth profile.

   QoS classification rules are handled by "qos-classification-policy".
   qos-classification-policy is an ordered list of rules that match a
   flow or application and set the appropriate target CoS
   (target-class-id).  The user can define the match using a
   more specific flow definition (based on Layer 2 source and

   "color-type" will be assigned to a service frame to identify its QoS
   profile conformance.  A service frame is "green" if it is conformant
   with the "committed" rate of the bandwidth profile.  A service frame

   is "red" if it is conformant with neither the "committed" rate nor
   the "excess" rate of the bandwidth profile.

Notes
-----
There is no "color-id" under "qos-classification-policy". The text should refer to "color-type" given that the "qos-classification-policy" substree is as follows:

        +--rw service
        |  +--rw qos {qos}?
        |  |  +--rw qos-classification-policy
        |  |  |  +--rw rule* [id]
        |  |  |     +--rw id                   string
        |  |  |     +--rw (match-type)?
        |  |  |     |  +--:(match-flow)
        |  |  |     |  |  +--rw match-flow
        |  |  |     |  |     +--rw dscp?           inet:dscp
        |  |  |     |  |     +--rw dot1q?          uint16
        |  |  |     |  |     +--rw pcp?            uint8
        |  |  |     |  |     +--rw src-mac?        yang:mac-address
        |  |  |     |  |     +--rw dst-mac?        yang:mac-address
        |  |  |     |  |     +--rw color-type?     identityref
        |  |  |     |  |     +--rw target-sites*
        |  |  |     |  |     |               svc-id {target-sites}?
        |  |  |     |  |     +--rw any?            empty
        |  |  |     |  |     +--rw vpn-id?         svc-id
        |  |  |     |  +--:(match-application)
        |  |  |     |     +--rw match-application?   identityref
        |  |  |     +--rw target-class-id?     string

The same applies for "cos" and "cos-id". 

The corrected text uses "color-type" instead of "color-id" and removes "cos"
and "cos-id" from the flow definition examples.
