Annotation

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.

Purpose

The purpose of this standard is to extend a bridge, and the management of its objects, beyond its physical enclosure using IEEE 802 LAN technologies and interoperable interfaces.
