LanExpert 80
Inline Gigabit Network Analyzer with Cable Test capabilities.
The LanExpert Network Analyzer is an essential tool for installing, monitoring, maintaining, upgrading or troubleshooting any network. The LanExpert utilizes a color touch screen interface to access one of the most complete suites of test and analysis functions available in a portable test tool.
PoE tests include voltage and inline current measurement to determine the actual power used by a powered device. The LANEXPERT also test cables for shorts, opens, split pairs, reversed pairs, measures cable length and generates tones for cable tracing.

LanExpert 85
Dual Media Inline Gigabit Network Analyzer
The LanExpert 85 network analyzer provides expert assistance for all tiers of LAN installers, technicians and managers working with either copper or fiber media.  The LanExpert 85 uses SFPs to change between copper, Single mode and/or multimode fiber SFPs.
 The LanExpert is a single solution for network professionals to quickly maintain and optimize networks from the fiber or cable to the packet.

Why LanExpert Series?

An extensive suite of test capabilities include: Link Detection, Ping and Trace Route to verify network connectivity; Single Ended or Inline Packet Monitoring, Filtering and Capture to identify and solve complex problems; User defined Traffic Generation and structured RFC 2544 Stress Test to predict network performance under varying load conditions; Loopback, VoIP and Email tests to ensure proper performance of key network services.

The Inline Mode allows users to non-intrusively monitor network traffic to identify protocols, port usage, VoIP statistics and network utilization. The LanExpert can capture and store up to 10,000 packets with user defined filters for detailed analysis in the field or downloaded over the network or to a USB flash drive. Using either RJ-45 or SFP port (LE85), tests including Ping, Link, Trace Route, DHCP and Discovery are used to quickly identify network problems. The LanExpert can generate up to 100% traffic loading with control of packet rate and size to demonstrate network performance at various traffic levels.

Additionally, a stress test that generates traffic and measures performance metrics, in accordance with RFC 2544, is also provided. The stress test can be conducted using the two independent ports on a single unit or used with a second unit located remotely on a network.

The LanExpert is a comprehensive network analyzer that allows users to deliver robust and reliable network services with a single test device. LAN installers, technicians, managers and service providers can now get expert network help at an affordable price.

FAQs - General
Q: My LanExpert finds many runt packets. Why is that? 

A: A runt frame is an Ethernet frame that is less than the IEEE 802.3 minimum length of 64 octets. Possible causes are collision, underruns, a bad network card or software. The LanExpert is design to find runts per the standard.
 
Q: My LanExpert does not connect to my network. What do I do? 

A: In factory default the LanExpert uses DHCP to retrieve its IP information. If your network is not DHCP, select Profile 2 and input an IP, subnet and gateway address to connect to your network. If the problem still occurs, then look at the current Port configuration under setup.
Q: Why don?t I see the partner?s capabilities?

A: If a Fixed speed is selected (in the Setup under Ports) then the LanExpert connects at that specific speed only and does not check the far ends capability. Select Auto under SPEED to see Partners Capabilities.
Q: Why does it say MDI-X Not Tested?
A: Psiber has its own Link As option called Auto+Detect. If this option is selected, MDI-X will be filled in with Auto MDI-X (LAN) or MDI-X (NIC). Auto+Detect allows for more information about the link to be displayed. Some SOHO gigabit switches might not work with this configuration.
Q: On the Link Screen, what does Partner mean under Signal?
A: 1000BASE-T requires that auto-negotiation establish a Master-Slave relationship between the two devices. Typically, a multi-port device (switch) will assume the role of Master and single-port devices (servers, end stations, etc.) will be the slave unit. The 1000BASE-T protocol has a means of arbitrating which device will assume a given role (master/slave). The purpose of this Master/Slave relationship is to determine which device will provide the clock for the link.
Q: Where do I see the IP information once I am linked?
A: Once Linked, select the down arrow on the scroll bar to view IP information including Port MAC, IP, Subnet, Gateway, DHCP, WINS, DNS1, DNS2, DNS3 addresses and Lease time (if using DHCP).
Q: Why do I only see Unassigned next to all the IP information?
A: Make sure the LanExpert is linked to the network and that your DHCP Server is working properly. If using static IP, then make sure the IP information is entered into the Ports profile under setup.
Q: What type of packets does the traffic generator produce?
A: The LanExpert uses UDP packets.
Q: Why don?t I see more information about the traffic under Traffic Generate?
A: Sync the IP address to another LanExpert or the other port of the current LanExpert (independent mode) on the network to see Received packets, lost packets, seq error, duplicate packets and roundtrip time.
Q: Why are the Port LEDs on top of the unit still flashing red?
A: If both are flashing, the LanExpert is trying to connect to the network. If one LED stops flashing and is a solid color then that Port is connected.
Q: Why does one of the LED turn a solid color but the other LED is still flashing?
A: Inline and Independent mode needs both network cables connected to the LanExpert. The unit will not start collecting data until both of the ports have established a connection to the network. Set configuration selecting Setup then press the PORTS button.
Q: What does Capture and Detectors mean on the SAVE screen? It seems that some tests on Analyze Network can be saved and some are not.?
A: SAVE - Capture is used to store the frames in the Frame Capture mode. Up to 8000 frames in each of 10 memory storage locations can be stored. Once stored the frames must be downloaded to the computer and viewed in the Wireshark protocol analysis software (this is a free software package go to www.wireshark.org to download the latest version). SAVE - Detectors is used to store all the information shown in the Link, Problems, Vitals, Protocols, Top Talkers, Devices, Ping/Trace, Email and VoIP. The LanExpert starts a database of information as soon as the unit Links with the network. Some information is collected without running a specific test. Running other tests adds more information to the database. This data is saved until the Link is broken and then a new database is started. Saving "Detectors" will save all the information in the database to either internal memory or external flash-drive. The LanExpert can Recall any internally save data. Data can be uploaded through the network or the external flash-drive and make a report using the LanExpert Console Application.

FAQs - Stress Test

Q: Can I use only one tester to make RFC2544 and traffic generate? If so, which mode would I choose?
 

A: You can run the Stress Test using the two ports on one LanExpert. The Independent Mode must be selected to do the Stress Test with a single LanExpert. You can also conduct the Stress Test using two LanExperts. One unit is designated as the remote unit and both are set to the Single Ended Mode.

Q: Normally, how much time is needed to do a RFC2544 test? What does estimated time mean in every item of RFC2544?
 

A: To conduct a test that meets 100% of the RF2544 requirements would take about 2.5 days of continuous testing. This is typically only done in a laboratory environment and rarely (if ever) done in the field. Field tests are almost always customized by the user to provide a thorough test within a more reasonable time frame. For example, the RFC2544 requires testing with eight different packet sizes. A typical field test will reduce the number of different packet sizes, many times only using the largest and smallest packet size, which greatly reduces the test time. The test times shown for each test on the LanExpert are for the default settings, which we have picked for field tests. As the user changes the test parameters these estimated times will change so that the total test time is known before the tests are started.

Q: What is recall?

A: Recall allows the user to recall saved data to do more analysis at a later point in time. The data is displayed exactly how it was collected under Analyze Network.
