    Introduction The Problem Log includes a listing of all problems that NetTool detected from the physical layer to application layer. Not every problem contained in this log is at the same level of severity; therefore, just because a problem is listed here does not imply that it is a catastrophic one. For example, Unwanted Protocols are included in this log, but they are not a major impediment to the operation of a PC on the network.

  • Page 54: Understanding The Problem Log Display

    NetTool Users Manual The Problem Log (Figure 6-2) is displayed: Figure 6-2. Problem Log Understanding the Problem Log Display There are nine types of problems listed in the Problem Log. Each type of problem has an icon associated with it. For example, a stethoscope is used to identify health- related problems.

  • Page 55: Things To Consider

    Things to Consider You can think of problems fitting into one of two categories: link connectivity or network. Link connectivity problems relate to cabling or cabling properties while network problems involve PC/network configuration settings or PC-to-server interactions. Generally, you encounter network problems while setting up or changing a PC’s connection to the network.
  • Page 56 NetTool Users Manual • Problem: Pair mismatch Explanation: The link pulse is being sourced on the same wire pair by both sides. This problem does not prevent connection to the network. NetTool automatically swaps the pairs to correct this problem. Remedy: Check the cabling.

  • Page 57: Network Problems

    Network Problems This section lists all of the network problems. Keep in mind that this is not an exhaustive list of troubleshooting steps. If you know what you need, the network administrator for the network you are troubleshooting can provide you with a lot of information to correct these problems.

DNS provides mapping between a machine name (e.g., www.fluke.com) and its IP address (e.g., xxx.xxx.xxx.xxx). EIA568 Electronic Industries Association Commercial Building Telecommunications Wiring Standard.
  • Page 92 NetTool Users Manual 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 full- duplex network is capable of 20 Mb/s data throughput, while a full-duplex 100Base-TX network is capable of 200 Mb/s throughput.
  • Page 93 Jabber A frame greater than the maximum legal size (greater than 1518 bytes) with a good or bad frame check sequence. In general, you should not see jabbers. The most likely causes of jabbers are a faulty NIC/driver or perhaps a cabling problem. Jitter Variability in latency, or delay.
  • Page 94 NetTool Users Manual NEXT Near-end crosstalk; crosstalk between two twisted pairs measured at the same end of the cable as the disturbing signal source. NIC (Network Interface Card) A network interface card is the adapter card that plugs into a computer to provide a network connection. Node Number Node number identifies the device of interest.
  • Page 95 Remote Collision A collision that occurs on the other side of a repeater. Since a 10BASE-T Hub is a multi-port repeater with a "segment" dedicated to each station, 10BASE-T collisions are remote collisions. Repeater A repeater is a layer-1 device that regenerates and retimes frames.
  • Page 96 NetTool Users Manual RTCP (Real-time Transport Control Protocol) A protocol that provides insight on the performance and behavior of the RTP media stream. Runts Typically defined as an Ethernet frame which is less than 64 bytes. Depending on what device is counting the runts, the frame check sequence may be good or bad.
  • Page 97 SNAP (Subnetwork Access Protocol) An IP protocol that is an extended version of the IEEE LAN logical link control (LLC) frame. SNAP provides access to additional protocols and allows vendors to create their own protocol sub-types. SNMP (Simple Network Management Protocol) Designed by the Department of Defense and commercial TCP/IP implementors, SNMP is part of the TCP/IP protocol suite.
  • Page 98 NetTool Users Manual Topology Topology is the organization of network components. The topology of Token Ring network components is a ring. Transport Transport refers to the physical method by which data is transmitted (e.g., Ethernet, Token Ring, etc.). Different physical network hardware and cable layout are required for different transports.
