Expert Sniffer® Internetwork Analyzers

The Expert Sniffer® Internetwork Analyzer provides diagnostic capabilities that help maintain, troubleshoot, fine-tune, and expand bridge/router-based leased line, frame relay, and X.25 internetworks. This revolutionary product captures data up to 2.048 Mbps and analyzes LAN protocols encapsulated within WAN data frames. With the Expert Sniffer Internetwork Analyzer, network managers can observe internetworks, uncover a wide range of problems, and quickly pinpoint those problem's origins.

In addition, the powerful WAN Analysis feature allows network managers to analyze SNA, X.25, and other terminal-to-host traffic up to 2.048 Mbps. As a result, the Expert Sniffer Internetwork Analyzer is the complete tool for growing and changing internetworks that includes both LAN-based and terminal-to-host environments.

PROTOCOL INTERPRETATION

Seven-layer protocol interpretation provides a detailed view of packets captured from an internetwork. It offers full support for over 200 protocols running over bridge/router-based leased line, frame relay, and X.25 internetworks. It displays the contents of each frame in English-language text at all seven OSI layers. The sophisticated filtering system allows network managers to focus on the trouble area. Flexible windowing displays network traffic in a variety of formats. Three formats Q Summary, Detail, and Hex Q are available simultaneously. Multiple viewports allow for up to six windows on a screen to enable comparisons among selected frames.

WAN ANALYSIS

WAN Analysis provides traditional three-layer terminal-to-host WAN analysis. Broad protocol support includes complete frame relay analysis. In addition to supporting frame relay, the WAN Analysis helps solve problems on traditional SNA, X.25, async, and bisync wide area networks at speeds from 50 bps to 2.048 Mbps. The WAN software operates off the same RISC-based board as the Expert Sniffer Internetwork Analyzer to provide one complete WAN Analysis tool in a single package.

WAN Analysis Features

FRACTIONAL SUPPORT T1
AND E1 CIRCUITS

Description

The T1 Pod and E1 Pod interfaces provide single-channel and multichannel access to T1 and E1 traffic for Network General's Sniffer Internetwork Analyzer. The T1 Pod monitors up to 24 DS0 channels or multiple DS0s for fractional T1 access. The E1 Pod monitors up to 32 64 Kbp channels or multiple channels for fractional E1 access. Both Pods route their data to the protocol analyzer. The protocol analyzer can then display and decode the data for analysis. Additionally, the T1 and E1 Pods track and report several important T1 and E1 physical alarm conditions.

Fractional T1/E1 Access

Program the T1 Pod to monitor from 1 to 24 DS0 channels at 56 or 64 Kbps, providing access to fractional T1 circuits. Program the E1 Pod to monitor from 1 to 32 64 Kbps channels, providing access to fractional E1 circuits. Multiple channels need not be contiguous, and different channels can be monitored for incoming and outgoing traffic.

Network Interfaces

The T1 and E1 Pods provide three interface connections to a digital circuit. These interfaces provide two receive ports (RX1 and RX2) and one transmit port (TX1). The E1 Pod can derive timing for signal synchronization from an external source via the Ext. Clock connector. The protocol analyzer provides power to the pod eliminating the need for a separate AC adapter.

Test Modes

Monitor

The T1 and E1 Pods Monitor test mode allows you to monitor and capture data from one or more 56 KB or 64 KB channels then display and analyze it with the Sniffer Internetwork Analyzer.

Terminate

The T1 and E1 Pods' Terminate test mode allows the Sniffer Internetwork Analyzer to monitor and capture data from one side of the T1 or E1 line while transmitting test data on the other.

Drop & Insert

The T1 Pod Drop-and-Insert test mode allows access from 1 to 24 56 KB or 64 KB channels without interrupting other channels. The E1 Pod Drop-and-Insert test mode allows access up to 32 56 KB or 64 KB channels without interrupting other channels.

FEATURES & BENEFITS

Expedites Problem Resolution and Avoids Costly Downtime:

EXPERT ANALYSIS

Expert Analysis is a vital network management application that observes internetworks, learns their unique characteristics, and automatically uncovers a wide variety of problems. Once problems are discovered, it quickly pinpoints their origins and expedites resolutions to complex problems. Expert Analysis reduces network downtime by helping to solve multilayered LAN and internetwork problems in real time.
