YANG Data Model for IS-IS L2 Bundle Member Link Attributes PICS

defines the framework to query IS-IS Protocol Implementation Conformance Statement (PICS). The module defined in this document is used to query an IS-IS PICS of advertising Layer 2 Bundle Member Link Attributes . The YANG modules in this document conform to the Network Management Datastore Architecture (NMDA) .

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 .

The YANG module is used to query an IS-IS implementation of advertising L2 bundle member link attributes for the conformance of the protocol implementation. Container "isis-pics-l2-member-attr" only exists when "isis-pics-l2-member-attr" is included in the list of "supported-isis-pics" in ietf-isis-pics module. The existence of a TLV support container means the support of a TLV. The details of the flags and features are included in the container.

This document uses the graphical representation of data models defined in . module: ietf-isis-pics-l2-member-attr +--ro isis-pics-l2-member-attr +--ro l2-bundle-member-attributes-tlv-support! +--ro shared-attribute-sub-tlv-support* uint8 augment /isis-pics:isis-pics/isis-pics:isis-pics-mptlv: +--ro l2-bundle-member-attributes-support? isis-pics:support

    The YANG modules defined in this document are
   designed to be accessed via YANG-based management protocols, such as
   NETCONF  and RESTCONF .
   These protocols have to use a secure transport layer (e.g., SSH
   , TLS , and
   QUIC ) and have to use mutual authentication.

 
    The Network Configuration Access Control Model (NACM) 
    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.
 

      
        Some of the readable data nodes in the ietf-isis-pics-l2-member-attr.yang module
        may be considered sensitive or vulnerable in some network environments. It is thus
        important to control read access (e.g., via get, get-config, or notification)
        to these data nodes.
      

   

  The document requests IANA to create a entry, called isis-pics-sr-mpls
   in the "IS-IS PICS" registry .
 
 This document requests IANA to add a new "identity" to the iana-isis-pics
  YANG module. The following statement is suggested:
  
  
    identity isis-pics-l2-member-attr {
     base "isis-pics";
     description
        "The identity for IS-IS PICS support of L2 bundle member link
         attributes.";
      reference
        "RFC 8668: Advertising Layer 2 Bundle Member Link Attributes
                   in IS-IS";
    }
