IEEE 802.1ag-2007 PDF
This standard specifies protocols, procedures, and managed objects to support transport fault management. These allow discovery and verification of the path, through bridges and LANs, taken for frames addressed to and from specified network users, detection, and isolation of a connectivity fault to a specific bridge or LAN.
Bridges are increasingly used in networks operated by multiple independent organizations, each with restricted management access to each othere’s equipment. This standard will provide capabilities for detecting, verifying and isolating connectivity failures in such networks.
Amendment Standard – Superseded. This amendment specifies protocols, procedures, and managed objects to support connectivity fault management. These allow discovery and verification of the path, through bridges and LANs, taken for frames addressed to and from specified network users. Connectivity faults can be detected and isolated to an individual bridge or LAN.
