NETWORK PERFORMANCE

7 MEASUREMENT TASKS

This chapter describes how to perform the following ATM and VLAN

Management network performance measurement tasks.

The following topics are described:

Measuring Network -wide ATM Traffic Performance Using the Bandwidth Icon

Measuring Device Level Performance

Displaying Port Level Statistics

LANE Component Statistics

Switch Domain Statistics

Measuring Network The Bandwidth icon opens the NNIx (Network Node Interface Traffic) Tool

-wide ATM Traffic that graphically displays the traffic patterns between ATM switches in the Performance Using network. It can be configured to collect, display and store information the Bandwidth Icon about good or bad (error cell) traffic patterns across the network.

The NNIx Tool can be configured to collect traffic information between two or more ATM switches. The ATM switches can be selected from a file browser type selector window called NNIx Browser which lists all the ATM switches in the network hierarchically based on Enhanced IISP address structure. Selected ATM switches can be added to the NNIx Map using the Hide (plus) Button. The Show Subtree (double plus) button can be used to add the entire ATM switch hierarchy (a root switch and all the switches below it). Upon adding switches to the NNIx map, the NNIx tool automatically starts collecting traffic information on the NNI links between the switches and the in and out traffic of each ATM switch.

The Configure option under the map menu of the NNIx map can be used to customize the NNIx tool.
