NBN ISO/IEC/IEEE 8802-1BR:2021

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, includ-
ing 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.
