1.  Introduction

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

   This document is being discussed within the microwave community.

   This document defines a YANG RFC 6020 [RFC6020] module for managing
   the radio link functionality of a microwave node.  The YANG module is
   augmenting RFC 7223 [RFC7223] in order to model a microwave link and
   interface in analogy with most other data links in a router or
   switch.

   In summary, the YANG module defined in this internet draft is:
   ericsson-radio-link (should be renamed to something like: if-
   microwave-radio-link) - Defines the model for basic configuration of
   a microwave radio link.

1.1.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

   Other definitions to clarify....

1.2.  Tree Diagrams

   A simplified graphical representation of the data model is used in
   this document.  The meaning of the symbols in these diagrams is as
   follows:

Ahlberg, et al.          Expires October 6, 2016                [Page 2]
Internet-Draft              Microwave RL YANG                 April 2016

   o  Brackets "[" and "]" enclose list keys.

   o  Abbreviations before data node names: "rw" means configuration
      (read-write), and "ro" means state data (read-only).

   o  Symbols after data node names: "?" means an optional node, "!"
      means a presence container, and "*" denotes a list or leaf-list.

   o  Parentheses enclose choice and case nodes, and case nodes are also
      marked with a colon (":").

   o  Ellipsis ("...") stands for contents of subtrees that are not
      shown.

2.  Objectives

   The aim of of the YANG models contained in this draft is to provide
   the model that is required to implement the basic radio link
   management of microwave devices.

   This model may be augmented by vendor specific YANG modules in order
   to manage product specific functionality.

   However, the intention is that it should not be necessary to have any
   vendor specific extensions to the YANG model defined in this document
   to implement standard microwave radio link connectivity.

3.  Microwave Model

   The microwave radio link model provides the parameters for managing
   the radio link part of a microwave node.

   The "ericsson-radio-link" YANG module has the following structure:

module: ericsson-radio-link
   +--rw radio-link-protection-pairs!
   |  +--rw radio-link-protection-pair* [name]
   |     +--rw name                             string

6.  IANA Considerations

   This document defines a new YANG module and the authors politely
   request that IANA assigns unique names to the YANG module file
   contained within this draft, and also appropriate URIs in the "IETF
   XML Registry".

7.  Security Considerations

   The YANG module defined in this memo is designed to be accessed via
   the NETCONF protocol RFC 6241 [RFC6241].  The lowest NETCONF layer is
   the secure transport layer and the mandatory to implement secure
   transport is SSH RFC 6242 [RFC6242].  The NETCONF access control
   model RFC 6536 [RFC6536] provides the means to restrict access for
   particular NETCONF users to a pre-configured subset of all available
   NETCONF protocol operations and content.

   There are a number of data nodes defined in this YANG module which
   are writable/creatable/deletable (i.e. config true, which is the
   default).  These data nodes may be considered sensitive or vulnerable
   in some network environments.  Write operations (e.g. edit-config) to
