Data Link layer information on every frame going through your network Even though the CompTIA Network+ exam places protocol analyzers in a hardware category, they aren t necessarily always hardware Some of the best and most useful protocol analyzers are software Use a protocol analyzer when being able to see the data on the network will help you answer a question Is something trying to start a session and not getting an answer Maybe a DNS server isn t responding Is some computer on the network placing confusing information on the network Is a rogue DHCP server sending out responses to DHCP requests In the same vein, a protocol analyzer helps you determine slowdowns on a network by giving you an idea of excess or unexpected traffic (see the Packet Sniffer subsection under Software Tools later in this chapter)
Creating Code 3 Of 9 In None
Using Barcode creation for Software Control to generate, create Code-39 image in Software applications.
Encoding Barcode In None
Using Barcode encoder for Software Control to generate, create barcode image in Software applications.
Cable Strippers/Snips
Universal Product Code Version A Printer In None
Using Barcode encoder for Software Control to generate, create UPC Symbol image in Software applications.
Bar Code Generator In None
Using Barcode generator for Software Control to generate, create barcode image in Software applications.
A cable stripper or snip (Figure 15-3) enables you to make UTP cables Even though the CompTIA Network+ competencies don t mention crimpers, remember you ll need them too You don t need these tools to punch down 66- or 110-blocks You would use a punchdown tool for that
Print ECC200 In None
Using Barcode creator for Software Control to generate, create Data Matrix 2d barcode image in Software applications.
Printing UCC.EAN - 128 In None

Multimeters
USS Code 39 Creator In Java
Using Barcode creation for Java Control to generate, create Code39 image in Java applications.
Drawing EAN13 In Objective-C
Using Barcode printer for iPhone Control to generate, create EAN-13 Supplement 5 image in iPhone applications.
Multimeters test voltage (both AC and DC), resistance, and continuity They are the unsung heroes of cabling infrastructures because no other tool can tell you how much voltage is on a line They are also a great fallback for continuity testing when you don t have a cable tester handy
Creating Bar Code In VS .NET
Using Barcode generation for ASP.NET Control to generate, create barcode image in ASP.NET applications.
Making ANSI/AIM Code 128 In Java
Using Barcode maker for Android Control to generate, create Code-128 image in Android applications.
Tone Probes and Tone Generators
Decode Code 39 Full ASCII In C#.NET
Using Barcode decoder for .NET Control to read, scan read, scan image in .NET applications.
Barcode Maker In None
Using Barcode generation for Excel Control to generate, create barcode image in Excel applications.
Tone probes and their partners, tone generators, have only one job: to help you locate a particular cable You ll never use a tone probe without a tone generator
CompTIA Network+ All-in-One Exam Guide
EXAM TIP CompTIA and many techs refer to the probe as a toner probe rather than a tone probe or simply a probe Don t be surprised on the exam You always need both a probe and a tone generator to use this tool properly
Butt Sets
Butt sets are the telephone person s best friend Use a butt set to tap into a 66- or 110-block to see if a particular line is working
Punchdown Tools
Punchdown tools (Figure 15-4) put UTP wires into 66- and 110-blocks The only time you would use a punchdown tool in a diagnostic environment is a quick repunch of a connection to make sure all the contacts are properly set
Figure 15-4 A punchdown tool in action
Software Tools
Make the CompTIA Network+ exam (and real life) easier by separating your software tools into two groups: those that come built into every operating system and those that are third-party tools Typical built-in tools are TRACERT/TRACEROUTE, IPCONFIG/ IFCONFIG, PING, ARP PING, NSLOOKUP/DIG, HOSTNAME, ROUTE, NBTSTAT, and NETSTAT Third-party tools fall into the categories of packet sniffers and port scanners EXAM TIP The CompTIA Network+ exam tests your ability to recognize the output from all of the built-in tools Take some time to memorize example outputs on all of these tools
15: Network Troubleshooting
TRACERT/TRACEROUTE
TRACEROUTE (Windows calls it TRACERT) is used to trace all of the routers between two points Use TRACEROUTE when you have problems reaching a remote system, to diagnose where the problem lies If a TRACEROUTE stops at a certain router, you know the problem is either the next router or the connections between them TRACEROUTE isn t perfect, because many routers block TRACEROUTE packets Try PATHPING when you re not sure whether TRACEROUTE is working properly Here s a sample TRACEROUTE output:
Tracing route to adsl-208-190-121-38dslhstntxswbellnet [20819012138] over a maximum of 30 hops: 1 1 ms 2 38 ms 9012138] <1 ms 41 ms 1 ms 70 ms Routertotalhome [19216841] adsl-208-190-121-38dslhstntxswbellnet [2081
