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 June 1, 2019 [Page 2] Internet-Draft Microwave YANG Model November 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 [RFC8432]. 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 [RFC8432]. 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 Ahlberg, et al.

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. 4.

Security Considerations The YANG modules specified in this document define schemas 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 these YANG modules 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) 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/mode, /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 data nodes represent the configuration of the radio-link- terminal and they 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: Ahlberg, et al. Expires June 1, 2019 [Page 40] Internet-Draft Microwave YANG Model November 2018 /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, /if:interfaces/if:interface/single/selected-cm, /if:interfaces/if:interface/adaptive/selected-min-acm, /if:interfaces/if:interface/adaptive/selected-max-acm, /if:interfaces/if:interface/if-loop, and /if:interfaces/if:interface/rf-loop: These data nodes represent the configuration of the carrier- termination and they 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: /radio-link-protection-groups/protection-group: This data node represents the configuration of the protection of carrier terminations. Unauthorized access to this data node could interrupt the ability to forward traffic or remove the ability to perform a necessary protection switch. XPIC: /xpic-pairs: This data node represents the XPIC configuration of a pair carriers. Unauthorized access to this data node could interrupt the ability to forward traffic. MIMO: /mimo-groups: Ahlberg, et al. Expires June 1, 2019 [Page 41] Internet-Draft Microwave YANG Model November 2018 This data node represents the MIMO configuration of multiple carriers. Unauthorized access to this data node 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: 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 Reference: RFC XXXX Ahlberg, et al. Expires June 1, 2019 [Page 42] Internet-Draft Microwave YANG Model November 2018 It is proposed that IANA should register a new IANAifType TBD1 for the interface type radio-link-terminal and a new IANAifType TBD2 for the interface type carrier-termination at [IFTYPE-IANA-REGISTRY]. 9.
