-: Network Tools and Commands. 2 2
In this section of the course, we're going to talk about 3 3
the different network tools and commands 4 4
that we're going to use in troubleshooting our networks. 5 5
As we work through this section of the course, 6 6
we're going to discuss software tools, command line tools, 7 7
and basic network platform commands 8 8
that are used by networking technicians, 9 9
administrators and engineers. 10 10
For software tools, we're going to cover things 11 11
like Wi-Fi analyzers, protocol analyzers 12 12
and packet capturing, bandwidth speed test, port scanners, 13 13
iPerf, NetFlow analyzers, TFTP servers, terminal emulators, 14 14
and IP scanners. 15 15
For command line tools, 16 16
We're going to focus on ping, ipconfig, ifconfig and ip 17 17
nslookup and dig, traceroute and tracert, arp, netstat, 18 18
hostname, route, telnet, tcp, dump and nmap. 19 19
You probably notice here, we're going to cover windows, 20 20
Linux and OSX command line tools in our discussions. 21 21
Finally, we're going to cover 22 22
some basic network platform commands 23 23
like show interface, show config, and show route. 24 24
These are three of the most common commands 25 25
that are used within the command line interface 26 26
of a router switch or firewall. 27 27
It's important to note, 28 28
that our goal in discussing these network platform commands 29 29
isn't to make you an expert in the command line interface 30 30
on a Cisco, Juniper, Brocade or other network platform, 31 31
instead, you should be able to run a basic command 32 32
and see the interface statistics, the running configuration, 33 33
or the current routes that are in place on a single device. 34 34
As we learned about these different tools and commands, 35 35
it's important for you to understand 36 36
that you might use a particular software tool 37 37
or command line tool for a particular purpose 38 38
inside your troubleshooting efforts. 39 39
Your focus here is being able to select the right tool 40 40
for a given issue or scenario presented on the exam. 41 41
So in this section, we're going to focus again 42 42
on domain five, network troubleshooting. 43 43
And this time, we're going to fully cover objective 5.3. 44 44
This states that, given a scenario, 45 45
you must use the appropriate network 46 46
software tools and commands. 47 47
So, let's get started with our coverage 48 48
of network tools and commands in this section of the course. 49 49
