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 Time-Division Multiplexing (TDM) interfaces in a microwave/millimeter wave node. The ETSI EN 302 217 series defines the characteristics and requirements of microwave/millimeter wave equipment and antennas. Specifically, ETSI EN 302 217-2 [EN302217-2] specifies the essential parameters for systems operating from 1.4 GHz to 86 GHz. The data model includes 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, 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, it 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 [RFC8561], 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 also available for other interface types. The designed YANG data model uses established microwave equipment and radio standards, such as ETSI EN 302 217-2; the IETF Radio Link Model [RFC8561]; and the ONF Microwave Model [ONF-model], as the basis for the definition of the detailed leafs/parameters, and it 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: Mansfield, et al. Expires 4 September 2024 [Page 3] Internet-Draft Microwave Radio Link YANG March 2024 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 is 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 ATPC Automatic Transmitter Power Control BBE Background Block Error BER Bit Error Ratio BPSK Binary Phase-Shift Keying CM Coding Modulation CT Carrier Termination ES Errored Seconds IF Intermediate Frequency MIMO Multiple Input Multiple Output RF Radio Frequency RLT Radio Link Terminal QAM Quadrature Amplitude Modulation QPSK Quadrature Phase-Shift Keying RTPC Remote Transmit Power Control SES Severely Errored Seconds TDM Time-Division Multiplexing UAS Unavailable Seconds XPIC Cross Polarization Interference Cancellation Mansfield, et al.

Tree Structure A simplified graphical representation of the data model is used in Section 1.4 of this document. The meaning of the symbols in these diagrams is defined in [RFC8340]. 1.3.

Explanation of the Microwave Data Model The leafs in the Interface Management Module augmented by RLT and 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", and "out- errors" are not within the scope of the microwave radio link domain and therefore are not applicable for RLT and CT. 2.

Security Considerations The YANG data models 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 Network Configuration Access Control Model (NACM) [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 data models 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 microwaveRadioLinkTerminal: /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 microwaveCarrierTermination: Mansfield, et al. Expires 4 September 2024 [Page 46] Internet-Draft Microwave Radio Link YANG March 2024 /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 of carriers. Unauthorized access to this data node could interrupt the ability to forward traffic. MIMO: /mimo-groups: This data node represents the MIMO configuration of multiple carriers. Unauthorized access to this data node could interrupt the ability to forward traffic. Mansfield, et al. Expires 4 September 2024 [Page 47] Internet-Draft Microwave Radio Link YANG March 2024 Some of the RPC operations in this YANG data model may be considered sensitive or vulnerable in some network environments. It is thus important to control access to these operations. These are the operations and their sensitivity/vulnerability: Radio link protection: /radio-link-protection-groups/protection-group/ manual-switch-working, /radio-link-protection-groups/protection-group/ manual-switch-protection, /radio-link-protection-groups/protection-group/forced-switch, /radio-link-protection-groups/protection-group/ lockout-of-protection, /radio-link-protection-groups/protection-group/freeze, /radio-link-protection-groups/protection-group/exercise, and /radio-link-protection-groups/protection-group/clear These data nodes represent actions that might have an impact on 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.
