Description

Amendment Standard – Superseded.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.
