Introduction
The LANEXPERT Inline Gigabit Network Analyzer is a handheld network tool that features protocol analysis, packet capture, traffic generation, cable testing and IPv4/IPv6 support. 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. The Inline Mode allows users to non-intrusively monitor network traffic (10/100/ 1000BaseTX) 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, downloaded over the network or to a USB flash drive. Use either RJ-45 port to test Ping, Link, Trace Route, DHCP and Discovery which will quickly identify network problems. The LANEXPERT can generate up to 100% traffic loading in 1% increments to demonstrate network performance at various traffic levels. A stress test that generates traffic and measures performance metrics (per 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. PoE tests include voltage and inline current measurement to determine the actual power used by a powered device. The LANEXPERT also tests cable for shorts, opens, split pairs, reversed pairs, measures cable length and generates tones for cable tracing.

Single Mode
Port Configuration
PORT CONFIGURATION has three modes the unit can be set to: SINGLE, INLINE or INDEP (INDEPENDENT). See Configurations in Apendix A, page
A-1 for more details on how to connect the LANEXPERT.
SINGLE mode connects one port on the LanExpert straight into a hub, switch or network device. SINGLE mode can be plugged into either Port 1 or Port 2. If both Ports are plugged in at the same time, then whichever Port links first will be enabled. This will cause the unused port to be disabled. The LEDs will indicate which Port is linked.
INLINE mode must have both ports connected to two network devices. INLINE mode can be used to observe the traffic flowing between two network devices. Disconnect the cable between the two network devices and connect one end into Port 1. Add a patch cable from the other network device into Port 2. The LanExpert is now between the two network devices. If a Port is not plugged in, the corresponding LED will flash red to indicate that no cable is plugged in.
INDEPENDENT mode must also have both Ports connected to one or two network devices. INDEPENDENT mode can inject variable traffic from one port onto the network while the other port listens to investigate the effects on the network. INDEPENDENT mode can monitor two separate network devices simultaneously. If INDEPENDENT mode is selected then both Ports 1 and 2 will need to be configured independently.
Inline Mode
Chapter 3
Setup
Ports - Link As
NOTE: If INDEPENDENT mode is selected, Port 1 parameters will be configured first. Port 2 parameters will then be available. The param­eters will be port identified for clarity.
Link As
LINK AS parameter determines whether the LANEXPERT is going to connect as an Auto MDI-X, Auto + Detect, LAN or NIC device on the network.
In INLINE mode, there are two additional options of forcing Port 1 to connect as NIC while Port 2 connects as LAN (P1: NIC P2: LAN) or vise versa (P1: LAN P2: NIC).
3-5
Auto MDI-X will auto crossover the port (LAN or NIC). It will link at the first compatible mode to provide faster testing.
Auto + Detect will auto crossover the port (LAN or NIC) and give more link information than auto MDI-X. It will test for all modes available before linking and will display the configuration for the link partners. Some SOHO (Small office, home office) gigabit switches are not fully compatible with Auto + Detect detection.
LAN will force the analyzer‘s port to look like a switch or a hub to the device it is connected to.
NIC will force the analyzer‘s port to look like a PC to the device it is connected to.
Speed/Duplex
SPEED/DUPLEX parameter can be conducted in an Auto-negotiating mode or forced to a single FIXED speed/duplex . For AUTO, select any combination of the five speed/duplex modes; 10H, 10F, 100H, 100F or 1000F. In FIXED, only ONE port speed/duplex can be selected.
NOTE: Press the DOWN arrow on the right of the screen to scroll to the next page of parameters.

Setup
Ports - Transmit
Transmit
TRANSMIT parameter displays how the LanExpert communicates with the user’s network, i.e. DISABLED, RFC894, LLC/SNAP or VLAN.
3-6
Ports Setup Screen II
DISABLE turns off all packet generation for non-intrusive
testing. No IP address is required for this configuration. RFC894 enables packet transmission. This protocol is the most
common standard using IP datagrams.
Tag
LLC/SNAP enables packet transmission. It is a legacy standard using IEEE 802.2 frames.
VLAN logically groups computers together across one or more switches. (For example the IT Department VLAN). The VLAN Identifier or tag specifies the VLAN to which the frame belongs. A value of 0 means the frame is not assigned to any VLAN. A ll other values may be used as VLAN identifiers allowing up to 4095 VLANs. VLAN 1 is often reserved for management of a network bridge.
Next to VLAN, the user can select or change the TAG number if there is more than one. Select the TAG=? button. A numerical keyboard screen is displayed. Valid entries are 0 to 4095. If a non-valid entry is chosen, then an error message will appear indicating the error. The screen will then revert back to the keyboard to re-enter a valid number. The CLEAR button removes the incorrect entered digits from the display. After selecting a valid number, select ENTER to return to the PORTS parameters screen.

Setup
Ports - MAC
Transmit - cont.
MTU is used to set the size (in bytes) of the largest frame that a given layer of a communications protocol can process. A higher MTU brings higher bandwidth efficiency. Not all network devices can process large packets which can reduce network performance.
Select the parameter button next to MTU. A numerical keyboard screen will be displayed. Valid entries are 100 to1518. If a non­valid entry is chosen, an error message will appear indicating the error. The screen will then revert back to the keyboard to re­enter a valid number. The CLEAR button removes the incorrect digits from the display. After selecting a valid number, select ENTER to return to the PORTS parameters screen.
MAC
MAC address parameters are displayed. The user has a choice of the FACTORY or USER MAC address.
FACTORY - MAC Address of the LANEXPERT is factory set and CANNOT be changed.
USER - User can enter a MAC address of their choice for device
cloning purposes. MAC cloning allows the LanExpert to simulate another network device by using its own MAC address to detect issues originating from that device. Select the address button to go to a Hexadecimal keyboard screen to enter a MAC address. The CLEAR button removes the entered digits from the display before entering a new address. After entering the desired address, select ENTER to return to the PORTS parameters screen.

Ports Setup Screen III Fixed
Ipv4 - is a protocol type to be used for all transmitted packets
used by traffic generation, PING, DHCP and other tests. FIXED allows the IP, Subnet, Gateway, WINS, DNS1, DNS2 and
DNS3 fields to be available to change. Selecting the button next to the name displays a numerical keyboard to enter the desired address. After entering the desired addresses, select ENTER to return to the PORTS parameters screen.
DHCP causes the IP, Subnet, Gateway, WINS, DNS1, DNS2 and DNS3 fields not to appear because they are unavailable for change. These will automatically be assigned to the LANEXPERT once a link is established with the DHCP server.
NOTE: If INDEPENDENT mode is selected, Port 1 parameters will be configured first, then Port 2 parameters will be available. The parameters will be port identified for clarity.

Discover
To edit or view the parameters for the SELECTED profile, select the DISCOVER button.
Discover sends out an ARP, NETBIOS and DNS request that actively
searches for network devices on a network. When performing the Discover action and the ARP checkbox is selected, the LANEXPERT sends ARPs to the entire range of the configured subnet (or the class C subnet if the LANEXPERT‘s subnet is wider than the configured subnet). If this subnet is the same as the physical network subnet, the first and last IPs are special IPs used for subnet multicasting. Selecting ignore will not send an ARP to them. Here are a few examples of how to configure.
3-14
Discover Screen
If you are unsure or if the LanExpert subnet is the actual subnet of the users’ network, set both checkboxes (i.e. neither the first nor the last IP will be ARPed).
If the LanExpert subnet is at the lowermost end of the actual subnet of the users’ network , set the IGNORE 1st IP and clear the IGNORE LAST IP checkboxes.
If the LanExpert subnet is at the uppermost end of the actual subnet of the users’ network – clear the IGNORE 1st IP and set the IGNORE LAST IP checkboxes.
Otherwise, clear both checkboxes.

Preparing to Use the Analyzer
Before selecting the ANALYZE NETWORK button on the HOME screen, determine how the LANEXPERT is to be connected to the device being tested (i.e. PC, netwok device, etc.). This will be based on how the analyzer was set up in the Ports Configuration section of the setup.
Single Mode - attach the patch cable to either Port 1 or Port 2. Inline Mode - attach a patch cable to both Ports 1 and 2. Indepentent Mode - attach a patch cable to both Ports 1 and 2.
If only one port is connected while in Inline or Independent Mode, that port will link while the other port continues searching for a link. The Port LED that has not established a link will keep blinking red and the screen will display a “LINKING“ message for the unlinked port until a link is established. Only minimum information about the linked port will be displayed. No additional information will be shown unless both ports are connected and a link established.

Traffic Generate
Traffic Generate
Select the TRAFFIC GENERATE button in the Bottom Area. The Traffic Generate Screen displays first the Remote IP address to where the frames are sent. Then it displays the size of the packets being sent with how many Transmitted and Received frames. If there are any lost packets then the LANEXPERT displays then number of frames lost with the percentage. Lastly, the remaining time in seconds will be displayed along with the percentage of the total time left.
If you configure for BROADCAST – that means that the LANEXPERT does not expect there to be a LANEXPERT port at the remote end.
If the configured IP of the remote end actually exists, data is
simply sent to the configured remote IP in the normal manner.
This means traffic is not broadcast all over the network but just
to that one IP. This is useful to “stress” a computer without
stressing the entire network.
If the configured IP of the remote end does not exist (it does not
respond to an ARP) then data is broadcast all over the users
network with that destination IP but a broadcast MAC is used.
This is useful to “stress” an entire network.
Each port has only one receiver and one generator. A LANEXPERT can use both receivers and both generators at the same time. Traffic Generator guidlines:
4-17
In INLINE mode you might think there were two ports – there is
really only one from the traffic generate point of view.
A port can be a local generator (sending traffic to somewhere
else) and be a traffic sink to another generator at the same time
– but both the remote generator and the remote sink must be the
same LANEXPERT.
A port cannot be generating traffic in the REMOTE->LOCAL di
rection and receive traffic from another LANEXPERT in its’
LOCAL->REMOTE direction (this requires two traffic sinks on
the same port), or vice versa (that would require two generat
tors).
The LANEXPERT will react to pause frames, and slow down the traffic generate rate. When broadcasting, the remote computer (if it exists) or the entire network (if it doesn’t) will slow down the LANEXPERT– you can read the “AVG RATE” data on the traffic generator screen to see what the maximum receive rate for the specific computer or the entire network is.

Traffic Generate
Traffic Generate
Traffic generate relies upon getting data back from the remote end when using LOCAL->REMOTE direction, and relies upon control frames in both directions when using REMOTE->LOCAL direction. This means that neither can quite reach 100% utilization if either:
a) the connection is using half duplex
b) using the REMOTE->LOCAL direction.

VoIP
VoIP
Select the VoIP button in the Bottom Area.
VoIP uses three different protocols. Detected phone lines could also be
video links or data links.
4-21
SIP is used for <Session Management> - the VoIP device/line
combination registers with the SIP server at intervals (usually
every few minutes). In this way, the location and status of the
device/line is maintained with the VoIP provider. This
authenticates the device/line also. Incoming and outgoing calls
are also managed through the SIP server.
RTP is used for the actual <streaming data> (i.e. audio in a
phone call) - when a call is made to/from a device/line then the
SIP server provides the device/line with the IPs of the RTP
server to use. The device/line then sends or receives a data
stream to/from the RTP server. Generally, this data is at a
consistent rate (usually 50fps for audio) and there are two data
streams (one for inbound data, the other for outbound).
RTCP is used to allow each end of an active RTP session to
communicate link quality information with each other. Not all RTP
devices or servers do this. If this occurs, the sender will
generally send one packet every few seconds. This allows the
VoIP provider to maintain knowledge of the performance of the
network.
There are separate entries for each line/device/server combination. The example on the following page shows one device, one server and two lines. The terminology used in this example is from the definition of SIP.

TO - Shows the IP:UDP port of the server with which the device/line last attempted to register.
FROM - Shows the IP:UDP port for the server which the device/line last received registration info from. These might be different because some systems send registrations to one server and receive the response from another.

MISORDERS is the number of times that frames were received out of order but, not lost (these frames generate poor signal quality, e.g. garbled audio).
LOST is the number of frames which were not found in the data stream (these frames generate poor signal quality if they reach a high volume).
JITTER is a measure of the timing of the frames (if the frame rate is 50fps for the data stream, then a figure of 1ms corresponds to a 2% uncertainty in the frequency of the audio signal).

Select Internal to save the data internally in the unit and use the LANEXPERT Console Application to extract the data. Select External and insert a USB flashdrive to save externally. Give the data a filename no more than eight characters long.
NOTE: Write down the internal numbers and the external filename to remember where you saved the data.
CAUTION: Do NOT remove the flashdrive while saving the data to it.The drive may become unreadable and needs to reformatted. Saving data may take several seconds. A percentage is shown for its progress and may apear to be “fixed” at times so please be patient.
Detectors (.DET files) 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 data base. This data is saved until the Link is broken and then a new data base is started. Saving <Detectors> will save all the information in the data base and when recalled any of the listed tests will show the information in the database at the time it was stored. So it is not limited to just a single test result. Any saved tests can be printed from the Screen Cature in the LANEXPERT Console Appication.

Stress Test
This chapter describes how to test the network with the RFC2544 Stress Test.
Understanding RFC2544
The LANEXPERT Network Analyzer uses Throughput, Latency, Frame Loss and Back-to-Back tests to measure the performance of a network consisting of one or more active devices.
Throughput - defines the maximum number of frames per
second that can be transmitted without any errors. The test
starts at a mid-range frame rate and then compares the number
of transmitted and received frames. If no frames are lost, the
rate is increased until frame loss occurs. If frames are lost, the
rate is decreased until no frames are lost.
Latency - measures the time required for a frame to travel from
the originating device through the network to the destination
device and then back to the source. The frames are tagged with
a time-stamp during transmission. When the tagged frame is
received back, the latency is measured.
Frame Loss - measures the networks response to overload
conditions. Traffic is sent at the maximum line rate and then the
number of dropped frames is counted. When dropped frames
are detected, the test restarts at a slower rate. This test is
repeated until there is no frame loss for two consecutive
iterations.
Back-to-Back Frames - measures the maximum number of
frames received at full line rate before a frame is lost.

NOTE: If you are not connected to a network that has DHCP or con­nected directly into the other port of the LanExpert with a cable, you must select a fixed IP address that has the same subnet mask as Port 2.
If you are not connected to a network that has DHCP, press the DOWN arrow twice to display Port 1 IP address. Select FIXED and give PORT 1 an IP address, Subnet and Gateway IP address.
Press the DOWN arrow three more times to display Port 2 IP address. Select FIXED and give PORT 2 an IP address which is in the same subnet mask as Port 1. Select the same Subnet Mask and Gateway IP address as Port 1.
For Example, Port 1 IP address 192.125.1.100
Port 2 IP address 192.125.1.101
Make sure to change the Remote IP address to Port 2 IP address. Select STRESS TEST under setup to change the Remote IP.

NOTE: If you are not connected to a network that has DHCP or con­nected directly into the other a fixed IP address for both of the address are within ths same subnet mask.
NOTE: Since stress testing does not (and cannot by definition) respond to pause frames, it cannot be slowed down. This means you cannot perform stress testing on an active network. Remember, stress testing has a zero tolerance to lost frames – just a single frame lost is a failure of the test.

Select the STRESS TEST button from the HOME screen. This screen displays the port link connection and the IP address associated with that port. All Stress Test packets are sent to either the second port on the LANEXPERT or another LANEXPERT. The IP address for the other port or the second LanExpert must be entered in the Stress Test Setup and is shown as the Remote IP address.
There is a button under the Remote IP address labeled LOCAL-> REMOTE or REMOTE -> LOCAL. This describes where the packets originate from. Selecting LOCAL-> REMOTE describes the packet originates from the Local LANEXPERT and is sent to the remote LANEXPERT. This gives us an upstream configured test.
Selecting REMOTE -> LOCAL describes the packet originates from the Remote LANEXPERT and is sent to the Local LANEXPERT. This gives us an downstream configured test.
Select from one to four test(s) to be performed. The estimated time for each test is given. Select START to begin the test(s). Stopping a test before it is complete may give invalid results.

Throughput test results are shown as the maximum number of frames transmitted and the percent utilization of the total bandwidth with zero lost frames. One row of data is shown for each enabled frame size (up to 7 rows).

The above screens show two different examples of Stress Tests: The left screen shows the test results when Port 1 of a LANEXPERT is connected to a gigabit switch with Port 2 of the same LANEXPERT also connected to the gigabit switch. The maximum line rate is 100% of 1000 megabits per second (Mbps). The measured throughput of the switch under test is 98% of the maximum line rate. 98% of 1000 Mbs is 980Mbps showing that the switch is operating at full speed.
The right screen shows the test results when a LANEXPERT is connected to a gigabit switch and then converted and transmitted over a microwave link with a speed of 155 megabits per second. The microwave transmission is converted back to copper and connected to a second gigabit switch which is connected to a second LANEXPERT. The maximum line rate is limited to the speed of the microwave link of 155Mbps. Calculated utilization is 155/1000 = 0.155 or 15.5%. Actual tests measured a 15-16% utilization rate. The difference is due to rounding as only whole numbers are displayed.

Latency
Latency
Test results are shown as the minimum, average and maximum latency time (in microseconds) for each size frame that is tested. The total number of packets used in the Latency test is determined by the length of time and number of tests selected in Setup. One row of data is shown for each enabled frame size (up to 7 rows).
5-7
When the latency time varies, it causes issues with real-time services. For example, latency variation in VoIP applications would degrade the voice quality. Long latency can also degrade Ethernet service quality. In client-server applications, the server might time out or poor application performance can occur.
The screen on the left shows very small latency times which we would expect from going through only one switch.
The screen on the right shows much longer latency times. This is due to the fact that the sent packets have to go through different medias (i.e. copper and radio link) and speeds to make a roundtrip.
NOTE: Select another Setup button visible on the screen or by scrolling to the right or left with the white arrows or select the Exit button.

Frame Loss
Frame Loss
Test results are shown as Frame Loss percentage versus percent of maximum line speed for each packet size. The test starts at 100% of the line speed and steps down in selectable step sizes until two consecutive steps have 0% frame loss which ends the test. Dashed lines are displayed for line speeds not tested when the 0% frame loss is met.
In the first example below, the test shows 0% loss at both 100% and 90% of the maximum line speed which ended the test. Everything below 90% will also have no frame loss and is not tested. The line speeds less than 90% have dashed lines showing that frame loss rate was not tested.
In the second example below (based on the previous microwave link test),there was 100% frame loss down to 30% of the maximum line rate. Some frames were transmitted correctly from 30% to 20%. Between 20% and 10% transmission reached 0% frame loss. 0% frame loss was expected at about 15.5% because of the 155Mbps microwave link. More accurate results can be attained by changing the Frame Loss setup to a smaller step size such as 1%.

Back to Back
Test results are shown as the number of frames sent at maximum line speed until a frame was lost. The test is repeated for each selected frame size with one row of data for each frame size (up to 7 rows).

The screen on the left shows that the LANEXPERT can send a very large about of back-to-back frames before an error occurs. This shows that our single switch has good buffering capabilities to keep up with the flow of traffic.
The screen on the right shows that the burst of frames isn‘t as big as what can go through a single switch. Going through multiple devices and medias decrease the amount of back-to-back frames.
