Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). Scope This Standard specifies the devices, protocols, procedures, and managed objects necessary to extend a bridge and its management beyond its physical enclosure using IEEE 802 LAN technologies. To this end, it: a) Identifies and isolates traffic between ports within an Extended Bridge; b) Specifies a tag format for this identification; c) Establishes an Extended Bridge consisting of a Controlling Bridge and one or more Bridge Port Extenders; d) Specifies the functionality and the specific requirements of a Bridge Port Extender; e) Extends the MAC service of a Bridge Port across the interconnected Bridge Port Extenders, including support of Customer Virtual Local Area Networks (C-VLANs); f) Establishes the requirements of bridge components and systems for the attachment of Bridge Port Extenders; g) Specifies a protocol to provide for the configuration and monitoring of Bridge Port Extenders by a Controlling Bridge; and h) Establishes the requirements for Bridge Management to support Port Extension, identifying the managed objects and defining the management operations.
