00:00:07,310 --> 00:00:09,520
Hello and welcome to this lecture.

2
00:00:09,530 --> 00:00:15,560
So now we have the H.A. class are up and running we see that the P.C. has internet connectivity.

3
00:00:16,310 --> 00:00:22,770
So before we do the failover meaning that I will just shut down the first 48.

4
00:00:22,820 --> 00:00:31,460
You should also see that for example I will access the CLIA on the on the active master.

5
00:00:31,490 --> 00:00:36,280
So let's do this.

6
00:00:36,340 --> 00:00:39,300
I want to show you basically something that's important.

7
00:00:39,310 --> 00:00:43,170
So priority when the master is elected.

8
00:00:43,180 --> 00:00:49,910
It's just one of the things that are taking into consideration but it's not the first one.

9
00:00:49,930 --> 00:00:51,700
So if you want to know exactly.

10
00:00:52,030 --> 00:00:58,390
So hopefully this year I start if you want to know exactly basically what was the reason for electing

11
00:00:58,480 --> 00:01:06,070
one of the four the firewalls before that firewalls as master you would execute a command that you will

12
00:01:06,070 --> 00:01:07,390
see just in a moment

13
00:01:11,940 --> 00:01:20,250
so while waiting the CLIA council to start please know that the 48 VM running in in trial mode like

14
00:01:20,250 --> 00:01:22,650
it is now has some limitations.

15
00:01:22,650 --> 00:01:29,780
And one of them it's the speed the throughput the total throughput that that can go through it or flow.

16
00:01:29,880 --> 00:01:30,780
So it's limited.

17
00:01:30,780 --> 00:01:36,080
And when you're doing the labs you may experience latency so don't worry just wait.

18
00:01:36,090 --> 00:01:37,610
But it will work.

19
00:01:37,620 --> 00:01:42,160
So now let's say get system h a.

20
00:01:42,630 --> 00:01:43,950
So high availability

21
00:01:46,390 --> 00:01:48,110
status.

22
00:01:48,640 --> 00:01:53,860
And here we say so master selected using.

23
00:01:53,880 --> 00:02:00,210
So this this number is selected as master because we cannot see it so I will just put it in another

24
00:02:00,210 --> 00:02:02,670
tab just click this button here

25
00:02:08,760 --> 00:02:09,080
OK.

26
00:02:09,090 --> 00:02:10,310
So now it's boarded up.

27
00:02:10,380 --> 00:02:17,310
So it has here this sir Number is selected as the master because it has the largest value of override

28
00:02:17,310 --> 00:02:18,290
priority.

29
00:02:18,600 --> 00:02:23,670
And this one is selected as master because he's the only member in the cluster and you can see that

30
00:02:23,790 --> 00:02:27,230
it's basically the same certain serial number.

31
00:02:27,240 --> 00:02:29,950
So now we have the fourth gate up and running.

32
00:02:30,390 --> 00:02:33,440
We have ping that's working as well.

33
00:02:33,450 --> 00:02:37,600
So what we should do now is navigate to Janus tree.

34
00:02:37,770 --> 00:02:48,290
So let's see the the forget firewall interface first I'll click on it.

35
00:02:48,370 --> 00:02:49,270
Here is the master.

36
00:02:49,270 --> 00:02:50,110
He is a slave.

37
00:02:50,140 --> 00:02:55,600
And I will now just go to Janus three and on the 48 one which is the master.

38
00:02:55,600 --> 00:02:57,220
I will just say stop

39
00:03:00,130 --> 00:03:01,040
to 1.

40
00:03:01,060 --> 00:03:01,840
It's stopping

41
00:03:06,800 --> 00:03:08,060
and here is done.

42
00:03:08,660 --> 00:03:18,830
So now let's go again to basically VM or workstation and Windows 10 and log in again.

43
00:03:19,660 --> 00:03:26,770
So in the in the first in the first Tab 1 9 2 that once you say that 100 that 2 5 4 remember it was

44
00:03:27,030 --> 00:03:28,360
48 dash one.

45
00:03:28,600 --> 00:03:34,390
So admin click enter for log in and let us see the result.

46
00:03:34,390 --> 00:03:34,660
Now

47
00:03:38,530 --> 00:03:39,430
now here it is.

48
00:03:39,430 --> 00:03:45,430
So 48 VM 64 and now it shows 48 Dash 2.

49
00:03:45,430 --> 00:03:53,400
So this means that the failover was successful and now we have only one 48 firewall in the cluster.

50
00:03:53,440 --> 00:04:01,860
It has it is synchronized it has priority 1 28 It is 48 Dash 2 again and has the role of master.

51
00:04:01,960 --> 00:04:12,570
So if we navigate now to this to command prompt and they will do a control C let's take a look what

52
00:04:12,570 --> 00:04:18,150
happened so I'm going up up up.

53
00:04:18,170 --> 00:04:27,650
We have we have two packets here we could see some packets dropped like I know a couple of them three

54
00:04:27,650 --> 00:04:29,790
or four.

55
00:04:29,940 --> 00:04:30,250
No.

56
00:04:30,280 --> 00:04:35,220
So basically yeah the fell over was more than successful.

57
00:04:35,220 --> 00:04:39,110
We've seen we've seen I think two packets.

58
00:04:39,160 --> 00:04:39,520
Yeah.

59
00:04:39,610 --> 00:04:45,160
Two packets at one point and everything was just running like it should be.

60
00:04:45,160 --> 00:04:54,120
So basically you can you can consider it as no packet loss if we now go on the front page we will try

61
00:04:54,120 --> 00:05:01,350
to navigate to a different menu or something but anyway seeing the ping as successful it is already

62
00:05:01,880 --> 00:05:04,560
we would proof that it is working.

63
00:05:04,560 --> 00:05:06,840
So let's navigate now to something else

64
00:05:10,800 --> 00:05:16,360
and let's go to let's say products.

65
00:05:16,730 --> 00:05:18,080
So Internet is working.

66
00:05:18,140 --> 00:05:19,640
It is successful.

67
00:05:19,640 --> 00:05:22,760
Now if we also go back to 48 to

68
00:05:25,920 --> 00:05:28,650
we see that it is the only one in the cluster.

69
00:05:28,650 --> 00:05:30,950
It has the mass roll out no go.

70
00:05:30,960 --> 00:05:31,620
I will.

71
00:05:31,680 --> 00:05:35,690
I will now go back to the genius tree and power up.

72
00:05:35,790 --> 00:05:38,670
This 48 dash one VM so start

73
00:05:41,890 --> 00:05:42,670
48 1.

74
00:05:42,670 --> 00:05:43,930
It's starting.

75
00:05:43,930 --> 00:05:46,690
Let's look in the castle so this is 48 1

76
00:05:52,230 --> 00:05:54,140
just to make sure it is right.

77
00:05:54,150 --> 00:05:55,780
I will close it.

78
00:05:55,830 --> 00:06:00,850
Go to Janus three right click click on console.

79
00:06:01,180 --> 00:06:02,620
It will open a new one.

80
00:06:02,680 --> 00:06:10,840
So I want to make sure that this console is in sync with the the power up process of the 48 firewall

81
00:06:12,670 --> 00:06:14,020
here is.

82
00:06:14,470 --> 00:06:16,130
So it's up and running.

83
00:06:16,150 --> 00:06:24,590
Let's go back now to Windows 10 machine and I will click refresh.

84
00:06:24,770 --> 00:06:26,380
Now let's uh let's log in.

85
00:06:26,390 --> 00:06:29,360
So admin and hit enter

86
00:06:33,180 --> 00:06:34,370
and here go.

87
00:06:34,380 --> 00:06:38,130
So now the 40 gate one it's online again.

88
00:06:38,130 --> 00:06:45,690
And when trying to navigate to the 2 5 4 IP address we see that we have landed again on 40 gate dash

89
00:06:45,780 --> 00:06:46,740
one.

90
00:06:46,890 --> 00:06:54,000
Now when the HP boots up we will see again that the 48 one it's the master and the second one with the

91
00:06:54,000 --> 00:06:56,200
default priority of 128.

92
00:06:56,250 --> 00:06:57,880
It's again slave.

93
00:06:58,050 --> 00:06:59,760
So that'll be all for this session.

94
00:06:59,760 --> 00:07:08,520
We have seen the failover as being successful the the land user the end P.C. basically did not lose

95
00:07:08,520 --> 00:07:12,870
connectivity to the Internet and everything worked just as expected.

96
00:07:13,110 --> 00:07:16,290
So really thank you for your time and see you in the next lecture.
