ExpertNet Lite Assessment Tool - User Guide

About this guide

This guide is intended for BusinessPartners and Avaya Associates using the ExpertNet™ Lite Assessment Tool (ELAT) for the first time. It describes how to get started and how to use ELAT for customers purchasing an IP Telephony solution that requires an IP Network Readiness Assessment.

About the ExpertNet™ Lite Assessment Tool

ELAT is a software application designed to gather information from an IP network. The data gathered is used to produce a Network Readiness Assessment report. It is designed to run for an extended period of time (usually 5 days), in order to see trends in network performance. The data is summarized graphically and can be included in the report.

Three types of queries are used to perform the measurements: RTP tests, ping probes and SNMP GET requests.

●ELAT provides RTP test functionality through the use of Traffic Simulators, which are installed on remote machines on the customer network.

●ELAT supports two ping protocols: UDP (default) and ICMP. On some networks, the default UDP protocol may not work. (For example, a firewall may be configured to block traffic to certain ports.) In such cases, the user can switch the protocol to ICMP.

●ELAT Controller supports SNMPv1 and SNMPv2 protocols. It collects processor and layer-3 interface utilization variables from devices on network paths. For the Controller to be able to retrieve SNMP data, it must be configured with a list of SNMP community strings.

The ELAT Controller collects Round Trip Time and One Way Delay measurements along network paths. Network paths can be entered manually by the user, or discovered automatically. To discover paths automatically, the Controller employs, transparently to the user, a bundled ExpertNet Discovery Tool. The EDT tool discovers network topology in a scope configured by the user.
