802.1CS-2020/Cor1 – Corrigendum to IEEE Standard 802.1CS-2020

The full title of this corrigendum is “Standard for Local and Metropolitan Area Networks–Link-local Registration Protocol – Corrigendum 1 Corrections to Management Modules and Protocol Encoding”.

The scope of the complete standard specifies protocols, procedures, and managed objects for a Link-local Registration Protocol (LRP) to replicate a registration database from one end to the other of a point-to-point link and to replicate changes to parts of that database. A facility is provided to purge the replicated database if the source becomes unresponsive. Provision is made for a proxy system to operate LRP on behalf of a controlled system. LRP is optimized for databases on the order of 1 Mbyte.

The scope of proposed changes includes the correction of errors in the YANG module, SNMP MIB and TLV encoding.  These errors are documented in the following maintenance database entries:

  • 0348: ieee8021LrpTcMIB OID duplicate assignment
  • 0349: ieee8021LrpMIB OID duplicate assignment
  • 0351: 802.1CS-2020 YANG is not attached and does not validate
  • 0355: IEEE 802.1CS-2020 REVISION REQUEST on LRP TCP Discovery TLV

The purpose of this standard is to facilitate the creation of applications that distribute information through all or part of a network.

This project is needed to correct a small number of corrections to the YANG data model, Simple Network Management Protocol (SNMP) MIB and Link Layer Discovery Protocol (LLDP) type-length-value (TLV) specifications.
