Abstract
This document defines a YANG data model for control and management of
the radio link interfaces, and their connectivity to packet

1. Introduction
This document defines a YANG data model for management and control of
the radio link interface(s) and the relationship to packet (typically
Ethernet) and/or TDM interfaces in a microwave/millimeter wave node.
ETSI EN 302 217 series defines the characteristics and requirements
of microwave/millimeter wave equipment and antennas. Especially ETSI
EN 302 217-2 [EN302217-2] specifies the essential parameters for the
systems operating from 1.4GHz to 86GHz. The data model includes
Ahlberg, et al. Expires April 6, 2019 [Page 2]
Internet-Draft Microwave YANG Model October 2018
configuration and state data according to the new Network Management
Datastore Architecture [RFC8342].
The design of the data model follows the framework for management and
control of microwave and millimeter wave interface parameters defined
in [I-D.ietf-ccamp-microwave-framework]. This framework identifies
the need and the scope of the YANG data model, the use cases and
requirements that the model needs to support. Moreover, it provides
a detailed gap analysis to identify the missing parameters and
functionalities of the existing and established models to support the
specified use cases and requirements, and based on that recommends
how the gaps should be filled with the development of the new model.
According to the conclusion of the gap analysis, the structure of the
data model is based on the structure defined in
[I-D.ahlberg-ccamp-microwave-radio-link] and it augments [RFC8343] to
align with the same structure for management of the packet
interfaces. More specifically, the model will include interface
layering to manage the capacity provided by a radio link terminal for
the associated Ethernet and TDM interfaces, using the principles for
interface layering described in [RFC8343] as a basis.
The data nodes for management of the interface protection
functionality is broken out into a separate and generic YANG data
module in order to make it available also for other interface types.
The designed YANG data model uses established microwave equipment and
radio standards, such as ETSI EN 302 217-2, and the IETF: Radio Link
Model [I-D.ahlberg-ccamp-microwave-radio-link] and the ONF: Microwave
Modeling [ONF-model] as the basis for the definition of the detailed
leafs/parameters, and proposes new ones to cover identified gaps
which are analyzed in [I-D.ietf-ccamp-microwave-framework].
1.1. Terminology and Definitions
The following terms are used in this document:
Carrier Termination (CT) is an interface for the capacity provided
over the air by a single carrier. It is typically defined by its
transmitting and receiving frequencies.
Radio Link Terminal (RLT) is an interface providing packet capacity
and/or TDM capacity to the associated Ethernet and/or TDM interfaces
in a node and used for setting up a transport service over a
microwave/millimeter wave link.
The following acronyms are used in this document:
ACM Adaptive Coding Modulation

1.2. Tree Structure

chapter 3.1 of this this document. The meaning of the symbols in
these diagrams is defined in [RFC8340].
2. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.

3.2. Explanation of the Microwave Data Model
The leafs in the Interface Management Module augmented by Radio Link
Terminal (RLT) and Carrier Termination (CT) are not always
applicable.
"/interfaces/interface/enabled" is not applicable for RLT. Enable
and disable of an interface is done in the constituent CTs.
The packet related measurements "in-octets", "in-unicast-pkts", "in-
broadcast-pkts", "in-multicast-pkts", "in-discards", "in-errors",
"in-unknown-protos", "out-octets", "out-unicast-pkts", "out-
broadcast-pkts", "out-multicast-pkts", "out-discards", "out-errors"
are not within the scope of the microwave radio link domain and
therefore not applicable for RLT and CT.

5. Interface Protection YANG Module
The data nodes for management of the interface protection
functionality is broken out from the Microwave Radio Link Module into
a separate and generic YANG data module in order to make it available
also for other interface types.
This module imports modules from [RFC8343], and it references
[G.808.1].

7. Security Considerations
The YANG module specified in this document defines a schema for data
that is designed to be accessed via network management protocols such
as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer
is the secure transport layer, and the mandatory-to-implement secure
transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer
is HTTPS, and the mandatory-to-implement secure transport is TLS
[RFC8446].
The NETCONF access control model [RFC8341] provides the means to
restrict access for particular NETCONF or RESTCONF users to a
preconfigured subset of all available NETCONF or RESTCONF protocol
operations and content.
There are a number of data nodes defined in this YANG module that 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)
Ahlberg, et al. Expires April 6, 2019 [Page 39]
Internet-Draft Microwave YANG Model October 2018
to these data nodes without proper protection can have a negative
effect on network operations. These are the subtrees and data nodes
and their sensitivity/vulnerability:
Interfaces of type radio-link-terminal:
/if:interfaces/if:interface/carrier-terminations,
/if:interfaces/if:interface/rlp-groups,
/if:interfaces/if:interface/xpic-pairs,
/if:interfaces/if:interface/mimo-groups, and
/if:interfaces/if:interface/tdm-connections:
These lists represent the configuration of the radio-link-terminal
and it need to match the configuration of the radio-link-terminal on
the other side of the radio link. Unauthorized access to these data
nodes could interrupt the ability to forward traffic.
Interfaces of type carrier-termination:
/if:interfaces/if:interface/carrier-id,
/if:interfaces/if:interface/tx-enabled,
/if:interfaces/if:interface/tx-frequency,
/if:interfaces/if:interface/rx-frequency,
/if:interfaces/if:interface/duplex-distance,
/if:interfaces/if:interface/channel-separation,
/if:interfaces/if:interface/rtpc/maximum-nominal-power,
/if:interfaces/if:interface/atpc/maximum-nominal-power,
/if:interfaces/if:interface/atpc/atpc-lower-threshold,
/if:interfaces/if:interface/atpc/atpc-upper-threshold,

These data nodes represent the configuration of the carrier-
termination and it need to match the configuration of the carrier-
termination on the other side of the carrier. Unauthorized access to
these data nodes could interrupt the ability to forward traffic.

/radio-link-protection-groups/protection-group:
This list of protection groups and the constituent data nodes
represents the configuration of the protection of carrier
terminations. Unauthorized access to these data nodes could
interrupt the ability to forward traffic or remove the ability to
perform a necessary protection switch.
XPIC:
/xpic-pairs:
This list represents the XPIC configuration of a pair carriers.
Unauthorized access to these data nodes could interrupt the ability
to forward traffic.
MIMO:
/mimo-groups:
This list represents the MIMO configuration of multiple carriers.
Unauthorized access to these data nodes could interrupt the ability
to forward traffic.
The security considerations of [RFC8343] also apply to this document.
8. IANA Considerations
It is proposed that IANA should assign new URIs from the "IETF XML
Registry" [RFC3688] as follows:
Ahlberg, et al. Expires April 6, 2019 [Page 41]
Internet-Draft Microwave YANG Model October 2018
URI: urn:ietf:params:xml:ns:yang:ietf-microwave-radio-link
Registrant Contact: The IESG
XML: N/A; the requested URI is an XML namespace.
URI: urn:ietf:params:xml:ns:yang:ietf-interface-protection
Registrant Contact: The IESG
XML: N/A; the requested URI is an XML namespace.
URI: urn:ietf:params:xml:ns:yang:ietf-microwave-types
Registrant Contact: The IESG
XML: N/A; the requested URI is an XML namespace.
It is proposed that IANA should record YANG module names in the "YANG
Module Names" registry [RFC6020] as follows:
Name: ietf-microwave-radio-link
Maintained by IANA?: N
Namespace: urn:ietf:params:xml:ns:yang:ietf-microwave-radio-link
Prefix: mrl
Reference: RFC XXXX
Name: ietf-interface-protection
Maintained by IANA?: N
Namespace: urn:ietf:params:xml:ns:yang:ietf-interface-protection
Prefix: ifprot
Reference: RFC XXXX
Name: ietf-microwave-types
Maintained by IANA?: N
Namespace: urn:ietf:params:xml:ns:yang:ietf-microwave-types
Prefix: mw-types
