Hello there. And welcome to this Cisco CC and we switched 301 15 example. Of course.
00:06
My name is Phil intentionally on in this video, we're gonna focus on CVP on l l e p. Whenever we were at a switch within our network,
00:15
we would usually keep lit up the order devices
00:18
no dependent on your environment sometime. The cables aren't clearly marked,
00:23
or you may come across some situations where the cables run into the wall and there's no visibility to the other end of the cable. It is always best practices to be aware of what devices are connected within your network that dresses issue. We have to well known discovery protocols, the first being CDP
00:42
or assist for Discovery Protocol,
00:44
which is proprietary casus kel
00:46
on. And there's led or link local discovery particle dependent on the environment. If you have a network with all Cisco devices, is gonna be comin to run CDP,
00:58
however, and mix environments
01:00
which is also common.
01:03
L l e p would be the girl for choice. We were working a seedy P. If we want to very fighting the current CDP saddens we would use command show CDP
01:15
if we want to see the neighbors were also running city. We can use the command show CDP Neighbors in orderto enable see really globally We would use the command CDP run from global conflagration Would
01:27
No syrupy is enabled by default
01:32
Everyone a tweak A city timers
01:34
of global configuration would
01:36
we can use the common CDP timer and specify the timer in seconds. There's also CDP configuration for inter fees. When you're working with L E P
01:49
commands are similar. Note L l e p is disabled by default.
01:53
I'm gonna bring up a love and we're gonna see who see the P and L E T works between devices have lot of the favorite love and I'm going to start a section that phase configure and very quietly or two particles. First, we'll check the current city Sevens.
02:07
Here we can see the default
02:08
Hello Interval which is 60 seconds
02:13
on the whole interval off 180 seconds. If you want to see the CDP neighbors, we can do the show. CBP neighbors come on. Currently
02:21
no city neighbors are listed for here in this lab where we're not seeing any neighbors
02:27
is due to the fact that in the face is likely shadow
02:30
in our case in the love
02:31
And why is one connects by Aggie? Easier to, um There we have it. Interfaces, though, has bring the Inter pares back up as the same on N Y H two.
02:44
Okay, they're interferes is up. Understand?
02:49
Let's go back and wage one
02:52
on cereal. Now we can see a neighbor
02:55
on. We could see the interferes that the neighbor is using on the foreign they're using easier too
03:01
on on our local end we're using a zero.
03:07
You can also get more information about the neighbor.
03:09
If we talk on the C word,
03:13
Harry can get information such as the IOS devices running
03:17
and see. It's 15 to 4.
03:22
You're gonna associate capabilities for the device
03:25
Now we can also weak
03:27
the CDC timers. Big open ended, well, conflagration world.
03:30
And we want to change how often see pockets are transmitted. We would use the time or keyword by default. It's 60 seconds.
03:38
We can bring in under five seconds.
03:40
We can also change the whole time of facility. We would say CDP
03:46
now. We would specify in the whole time. In seconds it's good practice. That said the whole time three kinds that off the help line are very Run the show City Command
03:57
No, to see Pockets are going to find limited every five seconds
04:00
on the whole time. It's at the 15 seconds.
04:03
There are also some seriously options on the interface.
04:12
Now you know CDP is enable globally by default.
04:15
Come and see me run
04:17
everyone torn off Siddiqi on a specific interferes.
04:23
We'll use the command. No
04:25
CVP space enable
04:28
on this would effectively torn off CDP
04:30
on this in his own. Let's start our attention till l l e p First we can verify the LMP settings by using a command show. L l e t.
04:42
Well, notice right off the bat that l l e p is disabled. So in order to enable a lowly P, we're gonna go into go book on thick and we're gonna choose the option c is run.
04:53
This is gonna turn on led on this switch.
04:57
A miracle.
04:58
So know your locus. There's a lot of similarities in the sevens for l l e p the dot off Siddiqui
05:04
here we can see that led is gonna be sent every 30 seconds on. The whole time is 120 seconds. Every school are back. We can see
05:15
the timers are different for the default or a CD.
05:21
The default for the CDP. Hello. Time is 60 seconds on the whole time with 180 seconds. We're us with LDP. The default is story Seconds for the hell of time. On 120 seconds for the whole time
05:35
you can use a show L e p neighbors common to view the l l licky neighbors. In this case, we will need a thorn on L l E T and Y Edge, too.
05:46
If we go back to and why, everyone
05:49
and we run the show l a leaky neighbors. Come on
05:57
is gonna take a few seconds.
06:00
There we go. Now we can see. And why edge to the enlisted as an elderly p neighbor N y, as one when we consider output is similar to that of CDP.
06:12
Likewise, we can talk on the details keyword
06:15
American see similar information to that of CDP
06:19
on areas in ality.
06:21
We can also tweet there. Lily timers.
06:29
We will use the time Ricky work the chains, the Hello. Interval
06:32
on to change the whole time in the world, Would you? Is the key word whole time.
06:36
And now we can see the helo in the bone is gonna send out every five seconds
06:42
on the whole time interval is set the 15 seconds.
06:45
There are also some options under the interferes where l l e t
06:51
on here. We can choose the selectively
06:54
disabled
06:56
the transmission of led or
06:59
selectively disable
07:00
the reception off led traffic
07:05
if you wanted it or enough
07:08
transmission
07:09
on this interference,
07:11
we would say no.
07:13
Lllp transmit. Understood effectively disabled lllp transmission on this interferes.
07:18
All right, let's go back to the slaves.
07:21
All right, look in her slaves. We have opposed assessment question,
07:26
which, from an disables l A leaky transmission on into his A
07:30
in global configuration would
07:32
we're going to the sympathies
07:33
and then you specify no elderly people enslaved
07:38
or me
07:39
global configuration more. You're going to the interferes
07:42
sub configuration level on, say, led run
07:46
or a C
07:46
off global conflagration. Would we enter the command led enable followed my own answers? A will go into the interface off configuration Load on, Then we would see the command no led transmit in the day's lecture,
08:01
we love that discovery protocols at the letter to level
08:05
specifically focused on CDP on L l E P which are two Lear to discovery protocols.
08:11
We first looked at CDP on the various commands. We can use the verify that city P is up and running.
08:18
Then he took it a bit. Florida we made some changes to the CDP timers.
08:22
Finding your attention was on L L E P, which is the open standard CVP
08:28
become period outputs the CVP. And we saw that most of the outputs are similar to that of CDP.
08:35
And then we treat some elderly timers Also,
08:39
Next we go,
08:39
we're gonna focus our attention on you. DLD it stands for uni directional injection.
08:46
First we look at why would use you DLD
08:48
following this, we're gonna focus on the steps. We will take the setup you DLD
08:54
in our switch
08:56
and finally we're gonna look at how we're very play that you DLD is set up in our switch.
09:01
This is for dimensionally and I want to thank you could choose in savory
