Chapter 2 Autotest and Central Setup Introduction q AutoTest and Central Setup are two critical elements of using your Network Assistant. To run AutoTest, press (AutoTest) on the top-level display. The Network Assistant will take one of several courses of action. q q q q If a link pulse is detected, it searches for devices on the network. The devices on your segment are shown by protocol on the AutoTest display.
OneTouch Series II Users Manual plugging it back in. This is also the same as pressing the (Rerun) button. Press a displayed device, cable, or hub icon to see a popup screen showing more information about that item. Close the resulting popup screen by pressing . AutoTest continues to discover devices and to count frames and errors even after you exit the screen by pressing (up one level). The Network Health test runs in the background (read Chapter 3).
Autotest and Central Setup Introduction 2 The Network Assistant will identify as a router any device advertising one of the following router protocols: RIP, IGRP, EIGRP, IRDP, or OSPF. Therefore, if a router is statically configured (i.e., is not sending out routing updates), it may not show up as a router. The Network Assistant will identify any IP device that is transmitting periodic router updates as a router.

Press the Left-Arrow and Right-Arrow keys to select digits to change (or touch the entry box directly at the desired position), the period (.) to move between IP address octets, the OK button to exit the display, and X to exit without saving changes. 2-16 Figure 2-14.
Autotest and Central Setup NetWare Print Server List 2 Central Setup This section covers the elements of the Central Setup screen (Figure 2-15) that are not covered in the Getting Started Manual: (SNMP Config). (IP Config) and IP Config From the Central Setup screen (Figure 2-15), press (IP Config) to access the IP Address screen (Figure 216). ace219s.bmp Figure 2-15.
OneTouch Series II Users Manual The address must be: Correct for the particular subnet to which the Network Assistant is attached (to determine what range of addresses is valid for a particular subnet you must know the subnet mask). Unique (there must not be a duplicate address on the network). The Network Assistant checks for duplicate IP addresses before using a source address. Therefore, you can choose just about any address.
Autotest and Central Setup NetWare Print Server List 2 Using DHCP to Get an IP Source Address The DHCP feature lets you use Dynamic Host Configuration Protocol to automatically get an IP source address for your Network Assistant. To activate DHCP, press (IP Config) from the Central Setup screen; then select DCHP. When you press (Get Address), the Network Assistant requests to lease an IP address from a DHCP server (Figure 2-18).
OneTouch Series II Users Manual The time at which OneTouch will renew its lease depends on whether the DHCP server issued a renew time period. If the DHCP server issued a renew time period, OneTouch will attempt to renew its lease at the specified time. Otherwise, OneTouch will attempt to renew the lease at 50% of the lease period. If OneTouch is unable to contact the DHCP server, it will try again to renew the lease at 87.5% of the lease period or the time specified by the server.
Autotest and Central Setup NetWare Print Server List 2 (Find Router) again cycles through a list of the detected routers. This lets you see more routers than just the first one detected. If the Network Assistant has discovered more than one router, it assumes you want to ping the busiest router, and so uses that router’s address. (Apply Address) to see if the Source IP Press address is duplicated on the local subnet. If a duplicate is found, its MAC address is displayed.
OneTouch Series II Users Manual Press SNMP Communities on the Security Setup screen to access the SNMP Community String List (Figure 2-20). The Network Assistant uses the “public” community string (password) as the first default and also provides the capability to enter four additional community strings different than “public” for any given device or set of devices. You can also password-protect strings so they are not visible on the Network Assistant screen.

Details about that station will be displayed as shown Figure 3-3. Press ( Tool Menu) to access the following (as applicable): q q q q q q IP Trace Route Ping + SNMP Ping Ping Key Device Add to Key Devices Find Node ace303s.bmp Figure 3-2.
Network Health Introduction 3 Each meter icon (except where indicated) has a logarithmic scale with 0 at the minimum, 10 at the midpoint, and 100 at the maximum. Tic marks identify the average and maximum data points. Average Maximum Current ace304s.bmp Figure 3-3. Station Detail The Network Health test display has six meter icons, each of which indicates the current, average, and maximum values. A representative meter icon is shown in Figure 34. Figure 3-4.
OneTouch Series II Users Manual Table 3-1. Network Health Meters Icon Description Press to display network utilization. Percent Display – Displays the utilization percentage for the last one-second sample period. Count Display – Displays the frame count, for the last one-second sample period. The meter’s scale switches to high range when the frame rate exceeds 10,000/second. Press to display the types of errors received.
Network Health Introduction 3 Table 3-1. Network Health Test Icons (Cont.) Icon Operation Press to display collision details (% collisions and collisions/second). Percent Display – Displays the number of collisions as a percentage of the number of frames received for the last one-second sample period. The Network Assistant identifies preamble collisions. Count Display – Displays the collision count for the last one-second sample period.
OneTouch Series II Users Manual Table 3-1. Network Health Test Icons (Cont.) Icon Operation Displays the number of unique source addresses monitored since the beginning of this test. Some of the source addresses may be off-segment, which are sourced from stations on the other side of a router. The meter has a logarithmic scale with 0 at the minimum, 25 at the mid-point and 250 at the maximum. Press to display the Station List. This information is the same for the Percent Display and Count Display.
Network Health Introduction Interpreting Error Results Collisions A collision is the result of two or more nodes transmitting at the same time on the segment. Collisions are not necessarily bad. They are a normal part of Ethernet’s operation. In general you need not worry about collisions unless the AVERAGE collision rate is greater than 20%. Excessive collisions are more often associated with too much network traffic and less often a physical problem with the network.
OneTouch Series II Users Manual If the percentage of frames with a bad FCS is greater than 1%, then it should be considered a serious problem that is affecting network throughput. A given rate of bad FCS frames has a much more serious effect on network throughput than a similar collision rate. This is because the retransmission time is so much longer.
Network Health Introduction 3 environment, a local station is one that is in the same broadcast domain as the Network Assistant. A remote station is one that is not on the same Ethernet segment or broadcast domain as the Network Assistant.

Chapter 4 Cable Tests Introduction The Network Assistant quickly identifies the most common cable and wiring faults on twisted pair cabling systems and automatically tests all four pairs. It also detects fiber optic cable and enables you to begin fiber tests if a fiber optic module is detected. You can perform the following tests and operations from the Cable Tests display (Figure 4-1).
OneTouch Series II Users Manual Cable Autotest Cable Length Results Press (Cable Autotest) to measure cable length, detect split pairs, and/or perform a wiremap test. The Network Assistant does not measure cable length when it detects a link pulse (i.e., when connected to an active device such as a Hub). When displaying cable length, the Network Assistant always reports the length to the first fault (e.g., opens, shorts, or split pairs).
Cable Tests Introduction 4 The Wiremap Cable test can be run as a standalone test or automatically when you run Cable Autotest or AutoTest. The standalone test and Cable Autotest are run under Cable Tests. To run a standalone test Wiremap Cable test, attach the cable to the Network Assistant and a remote unit to the far end of the cable under test, then press (Wiremap Cable). Figure 4-2 shows an example of the Wiremap Cable test results. ace402s.bmp Figure 4-2.
OneTouch Series II Users Manual If you explicitly run the Wiremap Cable test while the far end of the cable is attached to a Hub, you may see unexpected results like wires shorted together. This is a normal side effect of forcing a wiremap to be done on a remote device other than a Cable Identifier. Identifying Cables Use the Cable Identifiers in mapping a cable. (Cable Identifier #1 is standard equipment and comes with the Network Assistant; Cable Identifiers #2 through #6 are optional.
Cable Tests Introduction 4 Twisted Pair Cables Twisted pair cable is currently the most popular cable in LAN systems. The 10BASE-T standard for twisted pair cabling systems is much more popular than coaxial based Ethernet networks because it is easier to work with and is inherently more reliable. The 10BASE-T standard is valid for Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (ScTP).
OneTouch Series II Users Manual Special crossed-pair patch cords are useful when working with non-standard cabling systems. Reversed Pair A cable pair is reversed when two individual wires of a pair are reversed from end-to-end, as shown in Figure 4-3. A reversed pair is not necessarily a catastrophic failure. Some 10BASE-T adapter cards and Hubs can sense the reversed polarity and continue to operate. It is always a good idea, however, to fix this problem when found. 1 2 2 1 ace404f.eps Figure 4-3.
Cable Tests Introduction The symptoms of a split pair range from non-existent to a complete lack of communication. In some cases a split pair cable may work just fine for 10BASE-T but not at all for 100BASE-TX. 3 3 6 4 6 4 5 5 ace406f.eps Figure 4-5. Split Pair A split pair cannot be identified with a conventional wiremap test because it is the wire pairing that is incorrect rather than the physical connection. Another technique must be used.
OneTouch Series II Users Manual The Network Assistant is preprogrammed with typical NVP values for CAT 3, 4, and 5 UTP cable. In addition, there are two user-definable Cable Types for you to enter your own NVP values. Cable Termination In addition to determining cable length, the TDR technique provides information on the kind of termination at the far end of the cable and the cable’s characteristic impedance.

OneTouch Series II Users Manual Test Fiber Optic Cable This section describes how to use the Network Assistant with a Fluke Fiber Optic Meter (FOM) to test fiber optic cable. You can measure optical loss and output power on multimode or singlemode cable. The fiber tests require the following: See the instruction sheet provided with the DSPFOM/FTK for specifications and maintenance information for the fiber optic meter and source.
Cable Tests Test Fiber Optic Cable Table 4-1. Fiber Test Terminology Measuring Optical Loss After setting the reference, do not disturb the source connection as you make connections to measure optical loss (Figure 4-9).

Appendix D Glossary 10BASE2 Sometimes called ThinLAN or CheaperNet, 10BASE2 is the implementation of the IEEE 802.3 Ethernet standard on thin coaxial cable. The maximum segment length is 185 meters. 10BASE5 Sometimes called ThickLAN, 10BASE5 is the implementation of the IEEE 802.3 Ethernet standard on thick coaxial cable. The maximum segment length is 500 meters. 10BASEF A point-to-point fiber link. This is the draft specification for IEEE 802.3 Ethernet over fiber optic cable.
OneTouch Series II Users Manual 802.2 This IEEE standard specifies Logical Link Control (LLC), which defines services for the transmission of data between two stations at the data-link layer of the OSI model. 802.3 Often called Ethernet, this IEEE standard governs the Carrier Sense Multiple Access/Collision Detection (CSMA/CD) networks. Typical cabling standards are 10BASE-T, 10BASE2, and 10BASE5. Access Method The set of rules by which the network determines what node has access to the network.
Appendices Glossary D Broadcast A message that is addressed to all stations on a network. For Ethernet networks, the MAC broadcast address is FFFFFFFFFFFF. Client A client is a computer that make requests of a server. A client has only one user; a server is shared by many users. Broadcast Storm A situation in which a large number of stations are transmitting broadcast packets. This typically results in severe network congestion. This problem is usually a result of a misconfiguration.
OneTouch Series II Users Manual CSMA/CD (Carrier Sense, Multiple Access with Collision Detection) In CSMA/CD, each node or station has equal access to the network. Before transmitting, each station waits until the network is not busy. Since each node has equal access to the network, a collision (two stations transmitting at the same time) can occur. If a collision occurs, the affected nodes will wait a random time to retransmit. Ethernet uses the CSMA/CD access method.
Appendices Glossary Full-Duplex 10Base-T and 100Base-TX network operation using a switching Hub to establish a point-to-point connection between LAN nodes that allows simultaneous sending and receiving of data packets. Full-duplex performance is twice that of half-duplex performance. A 10Base-T fullduplex network is capable of 20 Mb/s data throughput, while a full-duplex 100Base-TX network is capable of 200 Mb/s throughput.
OneTouch Series II Users Manual Late Collision A collision that occurs after the first 64 bytes in a frame. In 10BASE-T networks, late collisions will be seen as frames with a bad FCS. Causes of Late Collisions are a faulty NIC or a network that is too long. A too-long network is one in which the end-to-end signal propagation time is greater that the minimum legal sized frame. Layer One of seven levels in the Open Systems Interconnection (OSI) reference model. See OSI.
Appendices Glossary Packet A group of bits in a defined format, containing a data message that is sent over a network. Protocol A set of rules that machines must follow to exchange information on a network. Primary Domain Controller A device that manages the common security policy and user account databases for a group of NetBIOS servers. The election protocols are such that the primary domain controller has a tendency to become the master browser.
OneTouch Series II Users Manual Short Frame A frame less than the minimum legal size (less than 64 bytes) with a good frame check sequence. In general, you should not see Short Frames. The mostly likely cause of a Short Frame is a faulty adapter card or driver. Signal/Noise Ratio The ratio of worst-case received signal level to noise level measured at the receiver input (expressed in dB). The S/N ratio may be expressed as NEXT(dB) Attenuation(dB), provided idle channel background noise is low.
Appendices Glossary Terminator A resistor connected to the end of a coax cable which is intended to match the characteristic impedance of a cable. Signals are dissipated in the terminator, eliminating reflections. Topology Topology is the organization of network components. The topology of Token Ring network components is a ring. Uptime The amount of uninterrupted time that a resource (such as a print server) has been available.
