Hello there and welcome to this Cisco CCMP switch 201 15 Example Up
00:05
on invisible year, we're gonna focus on troubleshooting error. Disable recovery. Often thing,
00:11
you'll usually find a port going into the air. Disabled Steal. This would result in engineer after manually log into the switch in order to re enable the port for access on the network. Know this may be fine if you are one or two switches in your network, but when you have lots of switches,
00:28
it's not gonna skill will.
00:30
Here comes the future known as Eric Disable Recovery that a rescue
00:36
this feature. Once configured, it can actually bring back a port up into an operable steam out of the area stable state, which would greatly reduce long time when you're troubleshooting their disable recovery feature. We have some steps here you should take. First you want to view the status of all your into pieces.
00:54
So in the first point we would do the show and for his status,
00:57
and then we were fighting. The include error that disabled
01:02
every one of you. The current air deceive detection seconds
01:06
we can use show era disabled detect.
01:08
This is gonna show us which features in a switch. Very disable is currently starring done for
01:15
on. In order to view the air disable recovery sections, we would do show very disabled recovery. Now, one support is in the air. This evil state The steps We would follow the bring back a port into an operable state. We would go into the inter fees from global configuration mood.
01:30
If we have multiple in the faces
01:34
in there the stable state, we can use the Interferes Range Command. Then you would use a shot Dunkleman
01:41
followed by the no show Dunkleman. Lastly, we would verify the interfaces
01:47
are backing down Operable state. I run into showing too fierce status command typing it again with the era disabled he word. I'm gonna bring up a lot so we can have a look at how the future works.
01:59
Here on the same re website
02:00
inside the loves
02:01
I've brought about the CCMP switch lamp
02:07
was Let's start and we need to go The last speech for the section. So we were the mix
02:12
next here we have exercised very disable.
02:16
Great. So no, we have more comforts. The work with
02:22
first I lose shoe in his status.
02:25
I'll fight that they include Aaron unstable
02:30
Here we can see
02:30
one of the port is currently in the area. Disabled state
02:34
In this love
02:36
a north of you they're the same detection settings. I'll choose the tech option.
02:40
Wonderful.
02:42
Oh, this I would quit.
02:43
Tells us which of the features air disable is currently enabled her
02:47
Some notable features are like port security. We have peace. Secure correlation. This relates to the court security
02:55
SERM Control
02:57
Wing flap
03:00
bpd You, Gary,
03:01
our prince fiction
03:04
you DLD
03:07
for unit directionally failures
03:08
by default error Disable our enabled on all of these teachers on In order to view the era recovery sentence,
03:16
we would do sure
03:17
error disabled recovery.
03:23
Ah, here we go
03:25
currently are disable Recovery is currently disabled
03:30
on all of the features.
03:31
So although we have ever disable itself being enabled on the future,
03:37
their recovery feature itself is disabled
03:40
Now, in order to bring the port buck out of the air disabled state in the inoperable states. If you look at that size here,
03:47
it's for a lot of it.
03:49
Villas tell us that in the piece has a Mac address statically configured in the switch, which is causing the interferes to go into the area. Stable state.
03:58
We can fight this.
04:00
And here we can see a mark addresses in stopping reconfigured
04:03
Thenardier Compliance are going to global configuration. Bode well under entities that I would take off this command.
04:11
My pre pendant. The work? No. In front of the month.
04:15
No, I'll do a shot and then a no shop.
04:16
This is gonna bring the entities out off the air. Disable state.
04:21
Everyone is showing that piece that this villain
04:25
you look at someone long messages.
04:27
We got a nice little message here telling us that the device has been detected
04:30
on the end of this state has been changed up. Now we're no longer seem any implicates showing up. If we wanted to change the air recovery settings, are we going to global configuration mode?
04:42
And then I would use the error disabled. Come on,
04:44
honey. Which was recovery
04:46
from here would need to specify the cause. This is gonna enable a recovering for a specific teacher in the switch.
04:55
So I would say cause
04:56
and if I wanted to turn on a recovery, for example,
05:00
Port security,
05:01
I would choose the secure violation. This would effectively car non era recovery for this particular feature, written. Now we've turned on a recovery for port security. Once it would have turned it on. I would want to change the pain because of equal pay laws.
05:15
It said Tree 100 seconds
05:19
so used in lethal You're here. I continue the interval That said 30 seconds.
05:30
How in every show error the same republic Come on under the Peace secure violation, which is a port security, it step to enable on the interval timer has been changed to 30 seconds earlier with timer was set for 300 seconds. Let school over a bit.
05:47
We can see the time set the trend in seconds like he called, which is five minutes.
05:55
Some other notable. A recovery option is we do show
05:59
her disable
06:02
cloud values.
06:04
This would really
06:06
like eating plants or, if you're running
06:10
clean congregation such as fact
06:13
in your cross,
06:15
and you can also take those values. You're going to global conflict and then you would say error, disabled. Upsetting on here, you would say the cause.
06:23
That's a for example, in flux,
06:26
and they're even says he played a maximum
06:28
perhaps alone before setting the area. Disable.
06:33
We'll use it. You were time. That's it, then.
06:38
In this love, this woman is not supported for it. Let's go back to the sites
06:44
Here we have a course assessment question. Which command takes support out of the air disabled state?
06:49
Hey,
06:50
we're going to global conflict Now you see the Sun Dunkleman
06:55
followed by no Sha
06:57
r B.
06:58
We're going into the interviewees conflagration on any issue Dunkleman followed by the notion of a woman
07:04
or C
07:06
when we can. Global conflagration more the cynical man No era disable should know
07:15
on answer is B. We would need to go in
07:17
the the Inter Theis sub conflagration. More
07:20
irregular with one interviews are. We can also use the interviews range on specify earrings off in pieces, which we want a play,
07:29
a series of configuration.
07:31
In this case, with regards to Aaron Disable, we release you the shot on an emotional woman.
07:36
In today's lecture,
07:39
he's focused
07:40
extensively on troubleshooting error, disabled recovery.
07:45
You look at the wrist methods we can use the very fine wherever interface is in error disabled state,
07:50
after which we would have focused our attention
07:54
on the various air recovery options.
07:57
This was then followed by bringing an interface out of the air disabled states.
08:01
Finally,
08:03
we turned on their recovery future within the switch. And then we look at some flap settings, which we can use regards when we have links that are flopping.
08:15
In the next week, you were gonna focus all over attention
08:18
on how we can discover neighbors,
08:22
our devices which are connected. Carling's
08:26
we're gonna use to well known Discovery Protocol
08:28
one, which is a Cisco proprietary, which is CD on the other being the open stunner, which is led.
08:35
This is Philip occasionally, and I want to thank you for choosing savory.
