  ITU-T A.5 justification information for referenced document IEEE 802.1AB-2016 in draft G.8021/Y.1341
1. Clear description of the referenced document:
Name: IEEE 802.1AB-2016
Title: IEEE Standard for Local and metropolitan area networks - Station and Media Access Control Connectivity Discovery IEEE 802.1AB describes the management objects and protocol that can be used for Layer 1 topology discovery in Ethernet LANs.
2. Status of approval:
Approved as standard.
3. Justification for the specific reference:
This specification has been developed by the IEEE and is used by the ITU-T without change. It specifies Link Layer Discovery Protocol which is used for discovering the physical topology from adjacent stations in IEEE 802 LANs. G.8021/Y.1341 defines the relevant functional components of this specification.
4. Current information, if any, about IPR issues:
No known issues.
5. Other useful information describing the "Quality" of the document:
New standard.
6. The degree of stability or maturity of the document:
New standard.
7. Relationship with other existing or emerging documents:
G.8011/Y.1307 specifies the Ethernet transport UNI and NNI for Ethernet Private Line services, including how to handle the control frames.
