Chapter 6

Using the 7C0x SmartSwitch Bridge View

A brief explanation of bridging methods; a tour of the Bridge Traffic View; using the Detail View; monitoring bridge operation; using the Filtering Database; configuring bridge operating parameters; setting forwarding thresholds, statistics, and notification options; setting polling parameters; enabling and disabling bridge interfaces

The SPECTRUM Portable Management Application (SPMA) Bridge View presents a series of windows that describe the bridging services available via the modules installed in your 7C0x SmartSwitch chassis. You can monitor bridge activity and performance and manage bridge configuration through the Bridge Traffic View and other related windows.

Bridging Basics

Bridges are used in local area networks to connect two or more network segments and to control the flow of packets between the segments. Ideally, bridges forward packets to another network segment only when necessary. Bridges are also used to increase the fault tolerance in a local area network by creating redundant bridge paths between network segments. This is so that in the event of a bridge or bridge segment failure, an alternate bridge path will be available to network traffic, without significant interruption to its flow.

The method a bridge uses to forward packets, choose a bridge path, and ensure that a sending station’s messages take only one bridge path depends on the bridge’s type: Transparent or Source Routing. This chapter describes viewing and configuration options related to Transparent bridges.

Source route bridging is not yet supported for the 7C0x SmartSwitch, as no Token Ring

TIP NIMs are currently available.
