Description / Abstract:
This standard specifies the devices, protocols, procedures and
managed objects necessary to extend a bridge and its management
beyond its physical enclosure using 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 802
LAN technologies and interoperable interfaces.
