1
00:00:00,750 --> 00:00:04,160
It on like section we're going to take a look to the troubleshooting
2
00:00:07,100 --> 00:00:14,600
troubleshooting is the process of diagnosing a problem and if possible resolving it the troubleshooting
3
00:00:14,600 --> 00:00:22,910
process is usually triggered when a person or a mentoring system reports a problem was the person reporting
4
00:00:22,910 --> 00:00:23,500
the problem.
5
00:00:23,510 --> 00:00:27,780
Often use clues about the symptoms of the problem.
6
00:00:27,860 --> 00:00:34,490
The trouble shooter the person who is going to have the problem has to find the root cause of the problem
7
00:00:34,520 --> 00:00:40,640
and the trouble shooter will be you guys most of the times.
8
00:00:40,710 --> 00:00:47,750
Let's go with it the stats of the trouble shooting the trouble shooting steps are the three steps.
9
00:00:47,750 --> 00:00:51,200
The first step is identifying the problem.
10
00:00:51,200 --> 00:01:01,460
This second is isolating the problem and the third is implementing a correct action and fix it to identify
11
00:01:01,460 --> 00:01:08,610
the problem to isolate the problem and to implement a quick action as well.
12
00:01:08,720 --> 00:01:15,250
And the users are your best friend always guys.
13
00:01:15,450 --> 00:01:18,840
Let's go over to troubleshooting commands.
14
00:01:18,970 --> 00:01:20,870
They're playing.
15
00:01:21,210 --> 00:01:32,300
Trace route S-sh Shumaker risk Thabo shoy interface breath swipe you troll on and the dieback commands
16
00:01:32,680 --> 00:01:38,300
to use for trouble shooting.
17
00:01:38,670 --> 00:01:45,330
We have two kinds of troubleshooting tools and there are software troubleshoot and they hardware trouble
18
00:01:45,370 --> 00:01:46,210
shoot to
19
00:01:49,050 --> 00:01:57,270
let's to using the overside module for troubleshooting we had some trouble shooting to skies and their
20
00:01:57,660 --> 00:02:06,680
top down bottom up the word on can clear for the path Saputo differences and the move the problem and
21
00:02:06,680 --> 00:02:15,900
up did go much deeper for this age solutions but I'm going to show you an example for example top down
22
00:02:15,900 --> 00:02:25,250
means we need to go downward from the oversize application like for example if one of your users reported
23
00:02:25,250 --> 00:02:29,840
a problem such that I can not serve on the Internet.
24
00:02:29,910 --> 00:02:37,630
The first thing I'm going to focus on is the application layer of the site which is I'm going to go.
25
00:02:37,890 --> 00:02:45,360
My friend please check the browser for example that you're using if you're using Chrome change it to
26
00:02:45,360 --> 00:02:48,900
operate and do it try to surf again.
27
00:02:49,020 --> 00:02:51,680
Then we're going to go down.
28
00:02:52,020 --> 00:02:57,230
Maybe I can check the network layer in here.
29
00:02:57,420 --> 00:03:04,440
I can check the IP address of this guy and if I and I can see that if it's obtaining the right IP address
30
00:03:04,440 --> 00:03:05,490
or not.
31
00:03:05,670 --> 00:03:10,030
Or maybe I can't check them they're telling clear for example.
32
00:03:10,050 --> 00:03:14,330
I can't check the lead to meters of that guy's Internet.
33
00:03:14,520 --> 00:03:17,350
And lastly I can say the guy for example.
34
00:03:17,350 --> 00:03:24,010
Hey man please check your cables if your cables are connected or not properly.
35
00:03:24,180 --> 00:03:24,970
OK.
36
00:03:25,050 --> 00:03:31,940
They're still using for the or some modules for the troubleshooting as an example.
37
00:03:32,370 --> 00:03:36,840
And here is how we can T-shaped the IP connectivity step by step.
38
00:03:36,840 --> 00:03:45,580
For example for us we can check the layer one for errors or up or down say it's there we can check a
39
00:03:45,570 --> 00:03:47,380
duplex mismatch.
40
00:03:47,520 --> 00:03:55,140
We can check the MAC addresses IP addresses ARP tables we can check the ports or we can check the ACLU
41
00:03:55,170 --> 00:03:58,260
or DNS as well.
42
00:03:58,800 --> 00:04:09,180
Let's go to spend now spend switched ports analyzer is an efficient high performance traffic monitoring
43
00:04:09,180 --> 00:04:10,350
system.
44
00:04:10,490 --> 00:04:18,300
There it's all mirrors traffic from a source port to our bill and to a destination port.
45
00:04:18,300 --> 00:04:25,050
This is sometimes referred to as session month or AInc span is used for troubleshooting connectivity
46
00:04:25,050 --> 00:04:32,150
issues and calculating network utilization and performance among many others.
47
00:04:32,310 --> 00:04:40,170
And here's the comfort here's how we can use the span for using the sperm for example if we want to
48
00:04:40,170 --> 00:04:41,390
worst traffic.
49
00:04:41,400 --> 00:04:54,260
If you want to mirror the traffic from Port 5 to port nine we're using a network analyzer to our ports.
50
00:04:54,600 --> 00:05:01,690
And we're simply mirroring our traffic form port to the port nine.
51
00:05:01,710 --> 00:05:12,920
As you can see here we have two types of spen and there are local span and the remote spare local locals
52
00:05:12,930 --> 00:05:20,300
mirrors the traffic between ports in the same switch remote span is similar to span.
53
00:05:20,460 --> 00:05:29,220
But it's support source ports source Whelan's and destination ports on different survey edge.
54
00:05:29,250 --> 00:05:35,070
For example if you want to configure a local span on your unswitched UK is the morning session and the
55
00:05:35,070 --> 00:05:40,630
session number command and you define the source and the destination interfaces.
56
00:05:40,680 --> 00:05:42,570
That's pretty straightforward.
57
00:05:42,570 --> 00:05:45,730
As you can see to configure it let's go with that.
58
00:05:45,750 --> 00:05:54,380
I piss away I personally is a Cisco proprietary Iris feature that ellos to collect information.
59
00:05:54,420 --> 00:06:02,700
For example response time latency Jinder and the of applause about network performance in the real time
60
00:06:03,930 --> 00:06:07,570
and here's the configuration of the IP SLA to come for your day.
61
00:06:07,590 --> 00:06:17,240
I personally for rather world for example are defining an IP of solid proof for us by tapping IP SLA
62
00:06:17,270 --> 00:06:20,900
and for example a number which is one in here.
63
00:06:21,120 --> 00:06:24,520
There we are defining an ICMP call.
64
00:06:24,720 --> 00:06:33,970
Or rather what I'm doing is I'm sending ping packets to this interface of the tree and I'm doing this
65
00:06:33,970 --> 00:06:37,900
action for aged 20 seconds.
66
00:06:38,070 --> 00:06:47,880
The frequency commands shows the frequency of the ICMP packets that I'm sending for then I'm using a
67
00:06:47,880 --> 00:07:00,120
schedule for my IP SLA and I'm typing IP a KGO one stop time and now and life will be for ever and defining
68
00:07:00,120 --> 00:07:06,960
the time range that I'm using this IP SLA to verify the silly configuration.
69
00:07:06,990 --> 00:07:18,180
I can show I pixelate configuration command and I can check the target address source address and Operation
70
00:07:18,180 --> 00:07:25,230
timeout and enter a number or some more informations like that.
71
00:07:25,290 --> 00:07:34,630
The second method that I can find the IP Eslick configuration is using the show IP SLA statistics comments
72
00:07:35,040 --> 00:07:43,080
and we can check the latest operations our time latest operation returned card number of success and
73
00:07:43,080 --> 00:07:47,610
number of failures are some more information like that.
