Hello and welcome back to I C nd one interconnecting Cisco and Network devices Part one.
This is Episode 12 to SoHo versus Enterprise Lands and cable pin outs and standards. I'm trending Daryl and I will be instructive for this course. In the last video we went over all this. I'm on one how it relates to the TCP I p stack
This episode we're gonna be covering the differences in SoHo and Enterprise lands. And then we'll be covering the different cable standards using today's networks and what their pen outs are.
So some of learning objectives today. We're gonna learn about a typical so whole land,
the simplified enterprise network
and some basic cable staters. And we want to look at their speeds or common names.
Look at some IEEE informal names and the cable types and length said that they're generally used with
that finally would look at the cable pen outs they use and where we use them.
So quick, Pre assessment here. What do you think? So host stands for
and again, I will give you a few seconds to go ahead and pause the video and try and find an answer.
Okay, Hopefully you found it.
This is going to be the small office Home office.
So? So it's typically one router, maybe a switch, maybe a wireless access point and usually quite a few devices between your son. Even nowadays, your TV, microwave coffeemaker,
computers, laptops, cellphones, printers, a little bit of everything
and a lot of times nowadays, your router, you're switching your where the *** excess point.
We'll actually be one device, and sometimes your modem will actually be in involved in there as well. So you'll have one device for everything. And so
No, on enterprise land.
This is for this. We're gonna assume that it's kind of a smaller enterprise, so it's only gonna have me, maybe one main router.
And then this one router is gonna kept connect to multiple switches that are usually separated by the department's or by floor. And in this example, it's actually separated by both. They have one department on each floor
connecting to the collapse distribution core layers, and we'll talk about those a little layer later in this course.
so some of the cable stairs we're gonna look at today is the
802.3 standard, which is the Ethernet standard, and that could go anywhere from 10 megabits per second to 100 gigabytes per seconds.
And U T P is the unshielded twisted pair. That's kind of what you generally see when you go toe
any electronics store to go pick up in Ethernet cable and STP, which is a shielded, twisted pair. She kind of has almost like a full of wrapping around the cables.
And then finally, your fiber optics, which is gonna be like a glass or a plexiglass material.
He's going travel a lot farther and a lot quicker, but they also come at a higher cost. So you you start to see that more in residential areas, but they're still not very large anymore.
So when you look at the Internet type here, this is gonna be kind of like the informal name
these sections here.
Is it the informal IEEE names? So some of the formal names, they're all going to start with 802.3. So for fast Ethernet.
If we look at the hunter mag here,
And then if you look at gig Ethernet.
You are looking at the
So if you look at the new miracle here is kind of like the speed and being
1000 is 1000 megabits or
and you look a 10 ton megabits here,
so switches and routers will usually contain one Ethernet standard for that device.
But sometimes I include a spot where you could put an S F p a small form factor plausible transceiver, which can usually run at an increased speed. So in my lab year, they're all fast Internet devices, so 100 megabits.
But there is a few that have the S F P portions that will run at gig speeds.
So the cable panels generally used is the T A 5 68 A and B.
For some reason, the cabling standard for
every night we're gonna have been in has been the 5 68 b.
So this is a straight through cable here. No, generally used the 5 68 bien pole sides,
and you actually want to look at the main peers that they transmit receive on it. 123 and six,
so one and two will be for transmit, and three and six will be on received depending on the device. And we go over that here in just a minute.
So you look over the crossover cable. You see that pairs one and two
are swamped with three and six over here on the right,
and three and six on the left is swamped with one and two on the right.
So where to use the difference and straight through and cross over cables The way that helped me to remember what you want to think about which layer the device operates in. Right
say Hubbard. Sweater, Baudelaire. Two devices, PC servers, routers those air. All layer three devices
now. Later, three devices they transmit on pears wanted to receive on three and six,
and then later two devices transmit on three and six. I wanted to,
so if you think about, let's say the work station in a switch here,
you want to use the street through cable
because the work station is going to transmit on pairs one and two, and that switch is going to receive them
on one and two. Whereas if you were to go from a switch to a switch,
you wouldn't want one side to be transmitting. I wanted to, and then it would cross over.
It would be receiving on three and six on the other side.
Now most of devices utilized the what is called the auto M D I X feature, where aching detects
whether it should be crossing over going straight through. And I can actually
alter the pin layouts for not physical penalize. Pathological.
So quick Pulse assessment here, which cable tight, being a straight through a crossover cables needed for a router and a server
again. I'll give you a few seconds if you want to pause the video and try and figure it out for yourself.
Okay, so if you got a straight through cable, you are absolutely correct because they're both working as Larry. Three devices. You need
Transmit and receive the same pairs.
And our next episode we're gonna be looking at the data link protocols
and kind of how all that operates together
and that being a layer to protocol
and again, if you have any questions or if you need help with this course,
go ahead. Feel free to send me an invite.
And again, thank you for watching the Ice CD course.
I look forward to helping you learn for the remainder of this
