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.

CSA Preface 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). For brevity, this Standard will be referred to as “CAN/CSA-ISO/IEC/IEEE 8802-1BR” throughout. At the time of publication, ISO/IEC/IEEE 8802-1BR:2016 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC. This Standard was reviewed by the CSA TCIT under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology and deemed acceptable for use in Canada. From time to time, ISO/IEC may publish addenda, corrigenda, etc. The TCIT will review these documents for approval and publication. For a listing, refer to the Current Standards Activities page at standardsactivities.csa.ca. This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 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.
