A new approach to network analysis

Imagine the ability to see what’s happening on your network by simply

connecting one single tool. Imagine automatically discovering network

devices and seeing inside your switches and routers. Imagine using the

power of one single tool to see and understand your network. Imagine

no further. Fluke Networks OptiView Integrated Network Analyzer is a

new approach to network analysis that provides you with the Network

SuperVision you need on all seven layers, along with the speed and

simplicity that your organization demands.

Get a complete view of your network and take control with Fluke

Networks OptiView Integrated Network Analyzer.

Turn it on, connect the network cable and your network appears

automatically. The information rich Network Front Page gives you

instant vision into what is happening on your network. The graphical

color display with touchscreen user interface provides information in an

easy to understand format, while giving you the ability to easily drill

down into any area by simply touching the target of interest. LEDs

continually display the current status of network activity in 10%

increments, providing visual notification when critical performance

problems exist. Additional LEDs indicate errors, collisions and

transmitted packets.

When a connection is made to a 10BASE-T or 100BASE-TX network,

the OptiView analyzer automatically performs a cable test, identifying

any problems with the cable and measuring the cable showing the

length to the attached port. The OptiView analyzer also configures

itself with a valid IP address, even without the use of DHCP. Then, the

advanced discovery system takes over to provide you with immediate

information such as percentage utilization of bandwidth, problems

detected, protocol statistics, devices and networks discovered. The

discovery system differentiates between hosts, interconnect devices

such as switches and routers, servers, printers and SNMP devices. The

discovery system also shows the number of IP subnets, IPX, NetBIOS

and AppleTalk networks.

Statistics at the touch of a button

Selecting the statistics tab on the OptiView Analyzer provides you with

a wealth of information on utilization, protocols, top hosts and

conversations.

Utilization and Errors

This function provides an historical analysis on the performance and

health of the network segment to which the OptiView analyzer, is

attached. The default data source is the OptiView analyzer but the Data

Source drop down menu lists all RMON and RMON2 devices that have a

history study enabled. This function allows you to select a device

anywhere on your network and display the information gathered by

that device. Even multi-port devices can be interrogated on an

interface-by-interface basis. The utilization graph shows percentage

utilization over time. Based on the pre-configured RMON history studies

for the selected device, you can choose from any of the existing history

durations. The OptiView analyzer time interval is selectable from 2.5

minutes to 15 hours. Each sample is time stamped and the cursor may

be moved over any sample to provide additional information shown in

the table below the graph. The utilization screen also allows you to

display the Top Talkers, Top Multicasters and Top Broadcasters.

Switching the view from utilization to error mode displays a graph of

errors by CRC Alignment errors, oversize and undersize packets, fragments

and jabbers. A touch of the Top Error Sources button displays the names

and addresses of the stations responsible for generating the errors.

Protocols

The protocols screen displays the current list of active protocols as

seen on the network segment to which the analyzer is connected. The

left side of the screen displays the protocol tree that may be expanded

to show all protocols, and sub-protocols running–from the MAC layer all

the way to the application layer. The protocol mix may be displayed at

any level in a pie chart or tabular format. When used in tabular mode

the protocols may be sorted by Packets or Octets by pressing the

Packets or Octets column header. The Top Hosts and Top Conversations

keys allow you to display the top hosts or conversations by protocol

type. For example, expanding TCP, selecting HTTP and pressing the Top

Conversations key will provide a display of all the conversations using

HTTP protocol.

Fluke Networks OptiView™ Integrated Network Analyzer

Top Hosts and Conversations

The Top Hosts screen displays the top transmitting or receiving devices

on the segment to which the analyzer is attached. When the MAC (All)

protocols is selected in the left hand pane, the host table may be

sorted by Packets sent or received, Octets sent or received, errors,

broadcast or Multicast packets. When a specific protocol or sub-

protocol is selected, the host table may be sorted by Packets or Octets.

The host table may be further sorted in ascending or descending order

by name or address. When Top Conversations is selected, the display

shows the conversations between hosts for the selected protocol. Top

conversations may also be sorted by packets or octets. You can view

additional information on the host devices by selecting a specific

conversation and touching Host A or Host B detail buttons.

Advanced Discovery Techniques finds Devices, Networks and Problems in seconds.

The OptiView analyzer starts its discovery process as soon as it is

connected to a network. Real-time results of devices, networks and

problems are discovered.

Device Discovery

Devices are discovered by monitoring traffic and by actively querying

hosts. For all discovered devices, the analyzer will present the best

possible information in terms of DNS Name, NetBIOS Name, SNMP

Name, IPX name and also addresses. The OptiView analyzer

differentiates between various types of host device. Interconnect

devices are further categorized by Routers, Switches, SNMP Hubs and

Wireless Access Points while Servers, Printers and SNMP agents are also

identified. The Device list will also include “Offnet” devices identified

by performing a ping or trace route to those devices. The devices listed

in the left hand pane is dependent on the category selected on the

device type. All devices may be sorted by in ascending or descending

order by Name, IP address or MAC address. By highlighting a specific

host and selecting the Host Detail button, you can obtain valuable

information on that host such as name, address, protocol and network

configuration. This overview screen allows you to add the device to the

“Key Device” category. By adding a device to Key Devices, the analyzer

will automatically test connectivity from the attached segment to that

device by performing an IP or IPX ping. A key device that fails to

respond, will show up in the Problem Discovery as “Key Device not

responding,” providing you with at-a-glance monitoring of critical

network devices.

Fluke Networks OptiView™ Integrated Network Analyzer

Network Discovery

This screen display shows your network categorized by network type.

Networks and all associated devices are discovered by traffic

monitoring and by actively querying the hosts. The left pane of the

display shows the network types (IP, IPX and NetBIOS). By expanding

and selecting the network type, a detailed summary is provided for all

local networks. For IP networks, the Subnet, Range, Mask and

Broadcast address is displayed. For IPX networks, the Network number,

Nearest Server and encapsulation types are displayed. For NetBIOS

domains, the domain name and Master Browser or Primary Domain

Controller information is displayed.

Fluke Networks OptiView™ Integrated Network Analyzer

Problem Discovery

The Problem Discovery screen shows all network hosts that may be

experiencing problems. Problems are reported according to severity–

error, warning or informational. Resolved problems are also displayed.

An example of the types of problems that are detected by the OptiView

Analyzers expert system are:

Errors Duplicate IP address

Incorrect subnet mask

IP address is subnet address

IP address is subnet broadcast address

Key device not responding

DHCP Server offered IP already in use

Lost DHCP lease

Warnings Default router not responding

Only device in IP subnet

Only device in IPX subnet

Proxy ARP reply for local IP

Information Only Device in NetBIOS Domain

The Problem Discovery information may be sorted in ascending or

descending order by Host, Severity or Description.

Fluke Networks OptiView™ Integrated Network Analyzer

SNMP Device Analysis

The overview screen displays valuable information about a selected

device. The device detail can include Names, Addresses, Protocols,

NetBIOS, Services, Router, Printer and Remote Monitoring capabilities

that the device supports. Names and addresses are reported as DNS,

SNMP, IPX and NetBIOS names, IP, IPX and MAC addresses. If a router

is selected, the routing protocols are reported and switch configuration

is reported by spanning-tree, transparent or source-routed. If the

device is capable of supporting remote monitoring, the level of

information provided is shown as SNMP, RMON or RMON2.

The integrated aspect of the OptiView analyzer is further illustrated

in this screen by the “Links and Launchers” drop down menu. The

capability of the selected device determines the type of links that are

displayed in the menu. Links and launchers are included for Telnet

sessions, Web Browser, Terminal Emulation, MIB Browsing and more.
