1
00:00:15,670 --> 00:00:20,840
So let's start with core 1, show interface gigabit

2
00:00:20,860 --> 00:00:23,550
1 0 23

3
00:00:23,710 --> 00:00:24,860
switch port.

4
00:00:25,720 --> 00:00:33,880
So the command here shows us that this interface is enabled as a switch port administer of mode is dynamic

5
00:00:33,910 --> 00:00:34,840
auto.

6
00:00:34,840 --> 00:00:43,110
In other words, it's using DTP but auto rather than desirable operational mode is static access.

7
00:00:43,210 --> 00:00:47,060
In other words it's acting as a access port.

8
00:00:47,080 --> 00:00:50,100
It's currently in VLAN 1.

9
00:00:50,860 --> 00:00:59,560
So interface range and before I do that we can do something similar on other ports such as gigabit 1

10
00:00:59,620 --> 00:01:00,470
0 1.

11
00:01:00,520 --> 00:01:05,080
This port notice it's also an access port.

12
00:01:07,330 --> 00:01:13,190
We can see something similar on gigabit 1 0 2.

13
00:01:13,210 --> 00:01:14,260
It's an access port, 

14
00:01:17,220 --> 00:01:28,220
1 0 3 is also an access port so let's do it firstly with the ports down to the access switches so gigabit

15
00:01:28,230 --> 00:01:35,470
1 0 1 2 3 switch port mode trunk.

16
00:01:35,820 --> 00:01:43,620
Notice we told that we need to configure the encapsulation first so we firstly need to use the command

17
00:01:43,640 --> 00:01:56,390
switch port trunk encapsulation dot1q and then we specify the mode as trunk, so do show run we've

18
00:01:56,390 --> 00:02:05,600
essentially typed these two commands on these three ports get into the habit of specifying the encapsulation

19
00:02:05,600 --> 00:02:12,740
first, some switches will require that you specify the encapsulation and that's because some switches

20
00:02:12,740 --> 00:02:24,210
support ISL and 802 dot 1q. Packet Tracer in this example only supports dot1q but you still have

21
00:02:24,210 --> 00:02:36,420
to specify the encapsulation so interface range gigabit 1 0 23 to 24 switch port trunk encapsulation

22
00:02:36,450 --> 00:02:39,570
dot1q switch port mode trunk,

23
00:02:42,940 --> 00:02:53,460
show run they are ports 1 2 and 3 and here are ports 23 and 24 the mode is being configured as trunk on

24
00:02:53,480 --> 00:03:02,460
those ports, we need to do something similar on core 2 notice we're getting spanning tree warnings

25
00:03:02,460 --> 00:03:11,550
about inconsistent ports and that's because core 2 is configured with access ports rather than trunk

26
00:03:11,550 --> 00:03:23,080
ports. So interface range gigabit 1 0 1 2 3 these 3 ports down to the access layer, switch port trunk

27
00:03:23,260 --> 00:03:27,370
encapsulation dot1q switch port mode trunk

28
00:03:30,930 --> 00:03:35,160
show run that configuration looks good.

29
00:03:36,000 --> 00:03:46,960
So interface range gigabit 1 0 23 to 24 switch port trunk encapsulation dot1q switch port mode

30
00:03:47,120 --> 00:03:47,600
trunk.

31
00:03:50,500 --> 00:03:51,880
Show run again, 

32
00:03:52,120 --> 00:03:55,230
go down to the end of our config, 

33
00:03:55,360 --> 00:04:04,770
these two commands have been configured on interfaces gigabit 1 0 23 and 1 0 24.

34
00:04:04,990 --> 00:04:06,430
That looks great.

35
00:04:06,430 --> 00:04:13,870
We are not gonna configure the link to the server or the router as a trunk port

36
00:04:13,870 --> 00:04:23,710
they will be access ports. Now on access 1 the two uplink ports gigabit 1 0 23 and 1 0

37
00:04:23,710 --> 00:04:24,680
24.

38
00:04:24,730 --> 00:04:33,420
need to be configured as trunk ports. So interface range gigabit

39
00:04:33,410 --> 00:04:37,070
1 0 23 to 24

40
00:04:37,070 --> 00:04:43,220
switch port encapsulation or trunk encapsulation dot 1 q switch port mode

41
00:04:43,220 --> 00:04:49,420
trunk. Show run scroll down

42
00:04:49,430 --> 00:04:59,910
there's our configuration on those two ports so that looks great.

43
00:05:00,020 --> 00:05:06,800
Now we need to do something similar on access switch 2 interface range gigabit 1 0 23

44
00:05:06,800 --> 00:05:18,390
to 24 switch port trunk encapsulation dot1q switch port mode trunk, show run those ports are now

45
00:05:18,390 --> 00:05:29,940
configured as trunk ports, last switch access 3 do something very similar interface range gigabit 1

46
00:05:29,940 --> 00:05:37,170
0 23 to 24 switch port trunk encapsulation dot1q switch port mode trunk,

47
00:05:40,110 --> 00:05:44,860
have a look at the config that looks great.

48
00:05:45,210 --> 00:05:48,590
You'll also notice that I'm constantly saving my configuration.

49
00:05:48,780 --> 00:05:56,880
That's a good habit to get into, save your configuration often in case you have problems.

50
00:05:56,880 --> 00:05:59,280
So we've configured the trunk ports.

51
00:05:59,280 --> 00:06:02,250
Now we need to configure the access ports.

52
00:06:02,260 --> 00:06:04,560
This port needs to be in VLAN 10,

53
00:06:04,710 --> 00:06:12,180
this port in VLAN 20 this port in VLAN 30 this port needs to be in VLAN 100 and this port

54
00:06:12,180 --> 00:06:15,170
will remain in VLAN 1.

55
00:06:15,360 --> 00:06:23,610
So I'll start with access switch 1 show interface gigabit 1 0 1 switch port.

56
00:06:23,610 --> 00:06:32,270
The port is currently in VLAN 1 needs to be in VLAN 10 so interface gigabit

57
00:06:32,280 --> 00:06:46,900
1 1 0 1 switch port mode access that is the default switch port access VLAN 10 show run what do we see

58
00:06:47,800 --> 00:06:59,030
that port is in VLAN 10 so that looks good now to verify show interface gigabit 1 0 1 switch port

59
00:06:59,750 --> 00:07:07,910
this is the best way to verify notice the port gigabit 1 0 1 as we can see with this show command is in

60
00:07:07,940 --> 00:07:13,420
VLAN 10, so that looks good.

61
00:07:13,520 --> 00:07:24,570
Second access switch interface gigabit 1 0 1 switch port mode access switch port access VLAN 20

62
00:07:24,620 --> 00:07:28,850
in this example, show run

63
00:07:29,960 --> 00:07:33,070
port is configured correctly in VLAN 20

64
00:07:33,200 --> 00:07:36,690
the true test however to verify is show interface

65
00:07:36,710 --> 00:07:38,050
gigabit 1 0 1

66
00:07:38,160 --> 00:07:39,370
switch port

67
00:07:39,770 --> 00:07:49,600
and what you'll notice here is an access port in VLAN 20, switch 3 interface gigabit

68
00:07:49,640 --> 00:08:03,750
1 0 1 switch port mode access switch port access VLAN 30 show interface gigabit 1 0 1 switch port this

69
00:08:03,750 --> 00:08:12,260
port as we can see with this show command is in VLAN 30 so that looks great.

70
00:08:12,590 --> 00:08:21,890
Now we need to put the server in the right VLAN interface gigabit 1 0 20 switch port mode access

71
00:08:22,100 --> 00:08:33,320
switch port access VLAN 100 show interface gigabit 1 0 20 switch port, port is now an access

72
00:08:33,320 --> 00:08:45,230
port in VLAN 100 so this port is correctly configured. The last port is on core 2 interface gigabit

73
00:08:45,230 --> 00:08:47,070
1 0 22.

74
00:08:47,210 --> 00:08:55,610
Now before I do anything notice at the moment show run shows us that there's no configuration under

75
00:08:55,610 --> 00:09:07,250
that interface but now switch port mode access switch port access VLAN 1. What is it gonna show

76
00:09:07,250 --> 00:09:07,750
us

77
00:09:07,850 --> 00:09:15,770
once we've done that configuration? Notice it's changed with this option to no negotiate which means

78
00:09:15,770 --> 00:09:24,770
it's disabled DTP, so DTP is being disabled on that access port DTP is still running on this port as

79
00:09:24,770 --> 00:09:32,400
an example, so show interface gigabit 1 0 24 switch port.

80
00:09:32,870 --> 00:09:41,870
Notice negotiation of trunking is on but if we look at port 22 negotiation of trunking is

81
00:09:41,870 --> 00:09:49,880
off so DTP has been disabled on this port because we made it an access port but on the trunk ports DTP

82
00:09:49,880 --> 00:09:57,740
is still enabled. Now in the real world DTP should be turned off you should turn off dynamic trunk protocol

83
00:09:58,280 --> 00:10:07,280
but in this lab, it's okay to use that in the exam make sure that you read the question carefully to

84
00:10:07,280 --> 00:10:14,240
see if you should turn off DTP. Okay, so I've successfully completed this part of the lab how did you

85
00:10:14,240 --> 00:10:14,900
get on?

86
00:10:14,930 --> 00:10:22,970
Were you able to configure hostnames, passwords,  VTP, VLANs, trunk ports, and access ports? How did you

87
00:10:22,970 --> 00:10:23,870
get on?

88
00:10:23,990 --> 00:10:29,630
Best way to learn is to practice, try it yourself and then watch me do it if needed.

89
00:10:30,530 --> 00:10:33,070
Okay so let's go to the next lab.
