Insert the following at end of subclause 1.1, relettering the bullet points so that they follow in order from those in the existing text. This standard specifies connectivity fault management protocols, procedures, and managed objects that provide confirmation of successful transmission of frames conveying specified data. This capability supports diagnosis of faults sensitive to, or caused by, particular data patterns, and their isolation to part of the transmission path. Connectivity verification can be carried out from any single point with bridged connectivity to maintenance points on the path, can isolate failures to communicate in a specific direction, and can be carried out while service is being provided to other users of the data path. To this end it a) Defines the extensions to connectivity fault management capabilities defined by Clause 18 through Clause 22 to facilitate diagnosis and isolation of faults sensitive to, or caused by, particular data patterns in frames transmitted by a service user; b) Describes the protocols and procedures for data driven and data dependent connectivity fault management (DDCFM). Amendment Standard - Superseded. This amendment extends the connectivity fault management capabilities introduced in IEEE Std 802.1ag-2007 to include tools to facilitate diagnosis and isolation of faults sensitive to, or caused by, particular data patterns in frames transmitted by a service user.
