Introduction

Network Traffic

Group Policies

Use the Group Policies feature to establish settings for all of your devices at one time. For example, you can set up Automatic Broadcast Control for your switches.

See the chapter Group Policies for more information on these features.

Network Traffic

The Traffic Monitor presents real-time information about the status of your network. You can set thresholds for five important measures, which when exceeded trigger an event that appears in the Alert Log. Use the Top5 View to determine who the Top Talkers are in a segment.

Network Growth

The HP Network Performance Advisor is an intuitive, intelligent interpre- tation tool that provides you with information about the entire network. The Advisor performs automatic traffic analysis and displays the results in easy- to-understand tables and charts. The reports created by the Advisor make useful recommendations on how to improve network performance. The Advisor also provides inventory information for each segment in the network. The analysis and data provided by the Advisor assist the system administrator in making a sound business case for changes to the network.

The Network Performance Advisor creates reports that make recommenda- tions about reducing utilization on the network segments to increase network performance. It provides proactive analysis of a network, in contrast to the real-time, reactive analysis provided by Traffic Monitor.
