Rahman Cisco March 20, 2016 Generic YANG Data Model for Connection Less Operations, Administration, and Maintenance(OAM) protocols draft-kumar-lime-yang-connectionless-oam-01 Abstract This document presents a base YANG Data model for connectionless OAM protocols. It provides a technology-independent abstraction of key OAM constructs for connectionless protocols. Based model presented here can be extended to include technology specific details. This is leading to uniformity between OAM protocols and support nested OAM workflows (i.e., performing OAM functions at different or same levels through a unified interface).

Introduction Operations, Administration, and Maintenance (OAM) are important networking functions that allow operators to: 1. Monitor networks connections (Reachability Verification, Continuity Check). 2. Troubleshoot failures (Fault verification and localization). 3. Monitor Performance An overview of OAM tools is presented at [RFC7276]. Ping and Traceroute [RFC792], [RFC4443] are well-known fault verification and isolation tools, respectively, for IP networks. Over the years, different technologies have developed similar tools for similar purposes. In this document, we presents a base YANG Data model for connectionless OAM protocols which supports generic continuity or Kumar, et al. Expires September 21, 2016 [Page 2] Internet-Draft Connection-Less OAM YANG model March 2016 reachability check, and path discovery. The generic YANG model for connectionless OAM is designed such that it can be extended to cover various connectionless technologies. Technology dependent nodes and RPC (remote process call) commands are defined in technology specific YANG models, which use and extend the base model defined here. 2. Conventions used in this document 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]. The following terms are defined in [RFC6241] and are not redefined here: o client o configuration data o server o state data The following terms are defined in [RFC6020] and are not redefined here: o augment o data model o data node The terminology for describing YANG data models is found in [RFC6020]. 2.1. Terminology TP - Test Point MAC - Media Access Control BFD - Bidirectional Forwarding Detection TLV - Type Length Value RPC - A Remote Procedure Call, as used within the NETCONF protocol Kumar, et al. Expires September 21, 2016 [Page 3] Internet-Draft Connection-Less OAM YANG model March 2016 2.2. 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: Each node is printed as: is one of: + for current x for deprecated o for obsolete is one of: rw for configuration data ro for non-configuration data -x for rpcs -n for notifications is the name of the node If the node is augmented into the tree from another module, its name is printed as :. is one of: ? for an optional leaf or choice ! for a presence container * for a leaf-list or list [] for a list's keys is the name of the type for leafs and leaf-lists 3. Overview of the Connectionless OAM Model At the top of the Model there is Multiple test-point-location-list keyed using test point location type. Under test-point-location- list, there is one or more test-point-locations. Each test-point- location is associated with vrf, oam-layers, tools, and technology. The vrf is used to describe the corresponding network instance. The technology indicate oam technology details. The tools is used to describe oam tools supported. The oam-layers is used to indicate relation of test point with other test points. The level in oam- Kumar, et al. Expires September 21, 2016 [Page 4] Internet-Draft Connection-Less OAM YANG model March 2016 layers indicate whether related oam test point is client layer, server layer or same or stiched layer. The Model is augmented to /nd:networks/nd:network/nd:node. oper is also defined at top of the Model to provide continuity-check common statistics. grouping is also defined for common per session continuity-check statistics. Under test-point-locations, there are tp-addresses, technology type, OAM tool which describe the attriburtes associated with test-point. 3.1. TP address In connectionless OAM, the tp address is defined with the following type: o MAC address o IPv4 or IPv6 address o a pair of source, destination addresses, and interface (Useful for BFD) o FEC o TLV address (RFC6428 (Figure 4,5, and 6)) 3.2. tools In connectionless OAM, the tools attribute is used to describe a toolset for fault detection and isolation, and for performance measurement. And it can serve as a constraint condition when the base model be extended to specific OAM technology. For example, to fulfill the icmp ping configuration, the "../coam:tools-ip/ coam:rfc792" should be set to "true", and then the lime base model should be augmented with icmp ping specific details. 3.3. OAM-layers OAM-layers is referred to a list of OAM layers above and below that are related to current test point. This allow users to easily navigate up and down to efficiently troubleshoot a connectivity issue. In this model, we have kept level default as 0, as none connectionless network OAM uses layer or level in its mode. Level is provided for scenarios where it might be possible to define layering relationship as it can be used to tie up interworking of fault at related oam layers. For example, there is a defect in the upstream path of the testpoint, the upstream path belongs to server layer LSP and the level is set to "-1", the downstream path of the test point belongs to client layer LSP and the level is set to "1", then we can Kumar, et al. Expires September 21, 2016 [Page 5] Internet-Draft Connection-Less OAM YANG model March 2016 stitch server layer LSP and client layer LSP at different level and track defect along this path. In another case, if the upstream path and downstream path of the test point is in the same level, the level is set to "0". The snippet below depicts an example of OAM layers. list oam-layers { key "index"; leaf index { type uint16 { range "0..65535"; } } leaf level { type int32 { range "-1..1"; } description "Level"; } ordered-by user; description "list of related oam layers."; } 3.4. rpc definitions The rpc model facilitates issuing commands to a NETCONF server (in this case to the device that need to execute the OAM command) and obtaining a response. In this document, we summarize the common OAM functions and define the generic rpc commands: continuity-check and path-discovery. In practice, these commands are supported by corresponding technology- specific OAM tools [RFC7276]. For example, for the IP OAM model, the continuity-check rpc corresponds to the IP Ping, while the path- discovery rpc command corresponds to IP Traceroute. Note that the rpc command presented in this document is the base building block, which is used to derive a model for a technology- specific OAM(i.e., icmp ping, lsp ping), the base building block should be extended with corresponding technology specific parameters. continuity-check: rpc continuity-check { if-feature continuity-check; description "Generates continuity-check as per RFC7276."; input { Kumar, et al.

Relation with other OAM YANG Model In this document we define a generic YANG model for connectionless OAM protocols. The YANG model defined here is generic such that other technologies can extend it for technology specific needs. The Generic YANG model acts as the root for other OAM YANG models. This allows users to traverse between different OAM protocols at ease through a uniform API set. The Generic YANG model for OAM provides a framework where technology- specific YANG models can choose to inherit constructs from the base YANG models without needing to redefine them within the sub-technology. 3.6.
