So when you consider selecting an interface
one of the important things to do is to know
what interfaces you actually have configured.
And by doing that you could find that on
the main launchpad.
On this start page, you're going to see
specifically what interfaces
are loaded on the host machine
and what you can do to customize them
before you use them.
And this is what the key is, right?
So, what are you going to do
to actually modify an interface?
Well, when you're modifying an interface
we're not necessarily going in and adjusting
you know, the duplex or we're not, you know,
changing the speed or anything like that.
What we're doing is we're setting up how
Wireshark inter-operates with the interface.
So, what that allows you to do is to,
you know, add a filter,
you can break up your files,
your segments, inter-segments.
You can tune new capture,
you can time your capture.
And you can limit the size of each capture.
So when you go into select,
just remember that you select
the interface that you want to adjust
and then you change your capture options.
Then you can modify the launch pad.
You can hide anything that you
it is that you don't want to see
as far as interfaces go.
There'll be many time at least in my machine,
I tend to have at least 10 or more interfaces.
When I want to go in and use Wireshark quickly,
the last thing I want to do is to have to go in,
find what interface it is that I want to use.
There's certain things that I don't need
Wireshark to show me so I'm going to
go in and I'm going to take those out.
Those, you will not see those, and
by doing so, it's going to allow
for less confusion and quicker monitoring
of the traffic coming through the network.
And to do that is when you go in
to the interfaces themselves.
You can choose to hide them.
So, in the graphic that I have up now,
you can select specifically,
ok, I don't really need to see
my bluetooth network connection.
So everytime I open up the launch pad
I want to hide that. I want to make sure that
that goes away and when I open up
I do not see that. I'm presented with
specifically, either my LAN
or my wireless LAN connection
and I'm good to go. By doing that,
again it avoids confusion.
It allows me to use the tool more effectively.
It lets me get in and do what it is
that I need to do quickly.
And then, I can also look at
the actual interfaces themselves
which is going to tell me a lot of information.
It's going to tell the status and the speed
of the interface which can be helpful.
So, for example, if I know that I'm having
a performance issue, I would likely or
would hope to be on a gigabit connection.
So I would be able to check that.
I will be able to see the amount
of packets coming in and out.
I will be able to see VLAN information,
the packet count, that is
when I run the capture, how many
packets are being counted or captured.
And I'll be able to see errors on the interface.
And I'll be able to look at the MAC
and the IP information.
Why is this important?
This is important because when you go
into Wireshark to run your capture,
the most relevant information
is what you want to see.
You want to consolidate what it is that
you don't want to see or remove it
completety so that you do not
get confused coming in and by doing so
you customized your launch pad.
You use policies and profiles
to customize everything so you can
come in quickly and you can
troubleshoot your problem.
