Hardware / Software Tools Flashcards
Wifi Analyzer
Allows you to track and analyze your wireless networks performance from different wireless components (WLC, APs)
Protocol analyzer / packet capture
Captures packets/frames on the network to later be analyzed
Ex: wireshark
Bandwidth speed tester
This allows you to test the throughput of your network using a 3rd party website
Port scanner
Allows you to scan your network for currently open ports/services and the IPs associated with them
Ex: nmap
iperf
Tests the performance of your network using the command line
NetFlow Analyzers
Network traffic analyzer
Simplifies network monitoring by using probes and collectors to collect data on the network and then create reports on the data it collects.
The probe is usually connected to the network through a tap or port mirror. The probe then sends all the data to the collector, usually a large storage device connected to other probes.
TFTP Servers
Used for small file transfers over the network with minimum overhead
Ex: Updating the firmware/software on a switch
Terminal Emulator
Used to remotely execute commands
Ex: SSH
IP Scanner
Allows you to scan your network for currently connected IP addresses
Ex: nmap
Cable Crimper
Allows you to fasten an RJ-45 connector to an Ethernet cable
Punchdown Tool
Allows you to terminate wires into a patch panel
Tone Generator
Used to identify cables and their runs
Puts a sound signal on the wire so you can trace it using a probe
Loopback Adapter
Takes the signal coming into the adapter and loops it
Allows you to see if the signal is going through correctly
Optical Time Domain Reflectometer / Time Domain Reflectometer
Tells you how long the cable is, and if there are any breaks in it and where they are located. Also identifies crosstalk, signal loss.
Multimeter
Allows you to measure the AC/DC voltage of a wall outlet or a computers power supply
(AC wall , DC computer)
Cable Tester
Allows you to confirm the connections on a cable are working by plugging both sides of the wire into it
More limited compared to a TDR, this just allows you to see if the pins in the wire are connected ex: 1:1 2:2
Wire Map / Mapper
A process or tool used to verify the proper connections are being made and to identify any faults in the wiring
Tap / Port Mirror
Allows you to copy the data from a specific connection. Either physically with a device or through software in a switch
Active Tap = Requires a power source to use
Passive Tap = Doesn’t require any power to use
Fusion Splicers
Allows you to fuse two ends of fiber into one line.
Spectrum Analyzer
Allows you to see what frequencies are in use around you
Snips / Cutters
Allows you to remove excess wire after crimping a cable
Cable Stripper
Allows you to remove the outside sheath of an Ethernet cable
Fiber Light Meter
Allows you to see how much light is being received on the other end of a fiber connection.
