Configurations

The OptiView WAN T1/E1 Analyzer supports Frame Relay, Point-to-Point and HDLC over T1 or E1, all on one platform. It is incredibly compact, being only a half rack width and single height (1U). The Analyzer's design provides the ability to monitor different types of links and future proof against migration to different link layer technology.

The OptiView WAN T1/E1Analyzer is equipped with two traffic interfaces that can simultaneously monitor both the DTE and DCE traffic data streams of a T1 or E1 link. Full duplex traffic patterns are displayed simultaneously for all link analysis.

Each OptiView WAN T1/E1Analyzer has a dedicated 10/100 Mbps Ethernet RJ-45 management port that allows it to be controlled remotely from any point on the network using the Optiview Analyzer Remote Software (included with the analyzer). Up to 8 users may access any single WAN Analyzer and perform different analysis concurrently. Settings of the OptiView WAN Analyzer system, such as SNMP Trap destinations, scope of discovery and user authentication and access level privileges, are easily configured from any workstation running the analyzer's Remote Software. The user security settings provide the necessary flexibility to comply with new requirements imposed by Sarbanes-Oxley for data viewing and access.

The Analyzer is literally as easy to install as a household appliance. Connect the WAN link through the Analyzer as a pass-through box (there is a built in tap), plug in the power supply and Ethernet management port, install the user interface software on a PC and launch the application. Network visibility is gained instantly as the analysis engines automatically provide instantaneous discovery and analysis into your WAN ? no configuration required.

Network View

The OptiView WAN analyzer can be used to identify WAN issues such as virus attacks, new unknown applications, unauthorized access attempts, and irregular traffic patterns. Once identified, undesirable traffic can be eliminated for improved WAN performance, possibly eliminating the need for link upgrades and delivering instant ROI.

Business applications which drive competitiveness require special attention over WAN links since they often introduce the most problems for remote users. OptiView WAN analyzers deliver the necessary flexibility to categorize applications and track their usage by user and over time. This helps to ensure centralized applications can perform over the WAN for remote user productivity.

The information-rich OptiView WAN Analyzer Front Page gives you instant vision into what's happening on your WAN link with easy-to-use drill-down capability. For any given WAN link, the analyzer displays the most critical elements of the circuit in a simple "at a glance" screen. Verify near-end and far-end router endpoints, T1/E1 physical layer connectivity, LMI heartbeat and number of VCs in one easy view.

In the same view, statistics such as link utilization, top hosts, conversations and applications allow you to see how valuable bandwidth is being consumed. A device inventory automatically classifies discovered network elements by type. Problems and alerts seen by the analyzer are displayed in a separate pane alerting you to any issues that might require further investigation. Each analysis area provides instant drill-down with a single click of the mouse.

Circuit Properties

Verify Virtual Circuit Configurations
Understanding your WAN configuration and status can eliminate finger pointing between the service provider and your business when issues arise. The OptiView WAN Analyzer continuously monitors the physical and link layers of T1 or E1 WAN circuits, immediately identifying any problems with the physical link. All VCs are automatically discovered along with DLCIs and associated router end points. Properties of each DLCI can be added to include a description, capacity, CIR and committed burst size.

Layer 1 and Layer 2 auto detection
The OptiView WAN analyzer automatically determines Link Speed (T1 or E1), framing format, line coding, DLCIs, encapsulation, LMI type and interface type. Users may configure unique circuit parameters including DS0 speed, fractional T1 assignments, maximum frame size, N392 error threshold, N393 monitored events count and T392 verification timer.

LMI Properties
LMI statistics are automatically generated for the link monitored including LMI errors, LMI details and VC availability. LMI errors include channel inactive seconds, reliability errors and protocol errors for both DTE and DCE. LMI details include state, channel inactive events, last channel inactive event timestamp, LMI type and interface type. VC availability statistics include VC name, status, last status change timestamp, outage count, percentage available, Mean Time Between Service Outage and Mean Time To Service Restore. All WAN physical layer statistics can be printed into an HTML report for delivery to your service provider if necessary.

Errors and Alarms

T1/E1 Errors and Alarms
The OptiView WAN Analyzer detects the most common errors and alarms that occur on T1/E1 links. Alarms detected include loss of signal, loss of frame, out of frame, AIS / RDI and far end SEF/AIS. These alarms are monitored separately for DTE and DCE sides and include current and historical alarm occurrences as well as number of seconds the link was in a given alarm state. Error packet counts for frame bit errors, line coding violations and path code violations are also presented for both DTE and DCE sides. Finally, performance statistics per ANSI T1.231 such as line errored seconds, errored seconds, bursty errored seconds, severely errored seconds, severely errored frame seconds, unavailable seconds and degraded minutes are also displayed. All error reports can be printed or forwarded in and easy to read HTML format.

Problem Log
Any errors that exceed user configurable threshold parameters are also displayed in the Problems log screen.

Device Analysis

Devices are discovered by monitoring WAN traffic for source and destination IP devices. For all discovered devices, the OptiView WAN Analyzer will present the discovered host by IP address and best name (DNS, NetBIOS or SNMP). The OptiView WAN Analyzer differentiates between various types of host devices such as Routers, Servers, SNMP agents and user workstations. If desired, the Device list may also be configured to include ?off-net? devices.

All devices may be sorted in ascending or descending order by Virtual Circuit, IP address or name. By highlighting a specific host and selecting the Host Detail button, you can obtain valuable information on that host such as which VCs it is using, which services are running (if a server), which routing protocols are running (if a router).

Statistics

Utilization
OptiView WAN analyzers offer a full battery of utilization statistics. Examine utilization for the entire circuit across all VCs or drill into any individual virtual circuit for specific utilization data by user group. Utilization statistics are updated every 5 seconds and up to one week's worth of data is stored on the Analyzer. Verify bandwidth usage is within design parameters. This capability lets you ensure service providers are delivering accurate throughput that is error-free and appropriately prioritized.

Application Analysis
OptiView WAN analyzer recognized today's most common applications and lets the users configure the identification of any custom applications unique to an organization. Examine application distribution for the entire circuit or for any selected virtual circuit. Protocol hierarchy is displayed in a familiar "file" format and categorized by OSI layer from the network layer through the application layer. Easily display protocol distribution up and down the OSI stack by clicking on the appropriate file and the protocol breakdown is immediately displayed on the right side of the screen. Both graphical and tabular views are available.

When a non-well known protocol is detected, it is automatically added to the monitor list and displayed with the port number denoted.

Top Virtual Circuits
The OptiView WAN Analyzer's unique design examines packets across all virtual circuits simultaneously. This allows users to sort virtual circuits in rank order by a variety of metrics including total octets, throughput, percent of total VC capacity, average percent of CIR and other metrics. This feature allows the user to quickly pinpoint problem VCs with a single, comprehensive sweep of all traffic across all VCs simultaneously.

Top Hosts, Conversations and Applications
Top hosts utilizing the WAN link are determined by the OptiView WAN Analyzer. Examine top hosts for the entire circuit or for any selected virtual circuit. Filter the top hosts you want to see by protocol using a familiar "file" format interface. Easily display top hosts up and down the OSI stack by clicking on the appropriate file and the top hosts are immediately displayed on the right side of the screen. Both graphical and tabular views are available.

Top conversations are also displayed using a similar format. So for example, you could view the HTTP conversations pairs consuming the most bandwidth on a particular VC.

A top applications view may also be displayed. This display aggregates all IP applications from both TCP and UDP traffic before sorting the applications in rank order.

Packet Capture

For in depth problem solving, the OptiView WAN Analyzer integrates a full packet capture function. The WAN Analyzer is capable of full line-rate packet capture and can capture up to 256 megabytes of data. Just select the Capture tab and immediately start capturing packets on your WAN link. For more refined packet captures, use the context sensitive filters. Simply select the host device from the device discovery screen, or a conversation from the statistics screen, click on the filter button and the packet capture engine is automatically populated with source and/or source and destination addresses of your selection. If you need even more selectivity, you can select a host or conversation using a particular protocol just as easily.

Simultaneously capture packets on multiple virtual circuits. Probe all packets across all VCs in real-time to dramatically improve troubleshooting and monitoring efficiency. And just as you would expect from a traditional protocol analyzer, the OptiView WAN Analyzer packet capture screen allows you to set a number of pre-capture filters including captures only on a specific DLCI, only FECN or BECN traffic, only DE frames, only traffic from a specific protocol and/or specific UDP and TCP port numbers, and many other filters. Set capture triggers to denote when to start your capture based on all these parameters as well.

Once you have the configuration you need, select Start Capture and let the analyzer filter and capture while you make another selection from the variety of tests to get a different view of your network. The analyzer continues to capture packets while you look at something else. When you stop the capture, select Save File to automatically save the capture file to your controlling PC's hard drive. If you have the Fluke Networks OptiView Protocol Expert (PE) installed on your PC, you can select View File to launch the application and view the decodes instantaneously.
