1
00:00:01,060 --> 00:00:05,930
To set up communication between switch one and switch to the sport needs to be configured as a trunk

2
00:00:05,930 --> 00:00:07,210
port.

3
00:00:07,290 --> 00:00:13,430
I'm also going to configure these ports as trunk ports so that we can capture traffic and see the encapsulated

4
00:00:13,430 --> 00:00:17,140
frames between the switches starting with each one.

5
00:00:17,210 --> 00:00:21,560
The first thing I'm going to do is make everything static.

6
00:00:21,560 --> 00:00:32,010
So switch port mode access on gigabit 00 and then switch port no negotiated to disable DTP.

7
00:00:32,420 --> 00:00:41,040
Do something similar on gigabit is 0 1 switch port mode access switch port No negotiate.

8
00:00:41,420 --> 00:00:46,100
Do show run.

9
00:00:46,120 --> 00:00:57,930
So this port 0 0 is configured as an access Port Vila in one DTP is disabled gigabit is 0 1 is configured

10
00:00:57,930 --> 00:01:03,840
as an access port and be lent to DGP disabled.

11
00:01:03,960 --> 00:01:10,980
So we now need to configure ports 2 and 3 is trunk ports and disable DTP interface gigabit zero to switch

12
00:01:10,980 --> 00:01:14,600
port mode trunk and it's going to fail.

13
00:01:14,700 --> 00:01:19,940
As you can see there because we have to top switch port trunk you kept isolation.

14
00:01:20,160 --> 00:01:28,980
And in this example we'll use that one key and then switch port mode trunk to make it a trunk port a

15
00:01:28,980 --> 00:01:36,890
trunk port allows multiple villains to traverse that port switch port No negotiate.

16
00:01:37,290 --> 00:01:38,680
Let's do something similar.

17
00:01:39,940 --> 00:01:49,760
On port three setting capitulation to dot one key set the mode to trunk disable DTP and then all know

18
00:01:49,760 --> 00:01:52,800
shut those two ports.

19
00:01:53,280 --> 00:02:06,800
So show interface give it a zero to switch port the command shows us that gigabit is 0 or 2 is enabled

20
00:02:07,160 --> 00:02:08,880
as a layer to interface.

21
00:02:09,170 --> 00:02:15,580
It's being administratively configured as a trunk and it's operating as a trunk encapsulation used is

22
00:02:15,680 --> 00:02:16,410
dot one.

23
00:02:16,410 --> 00:02:20,100
Q That's how it was configured and that's how it's operating.

24
00:02:20,210 --> 00:02:22,490
DTP has been disabled.

25
00:02:22,490 --> 00:02:32,520
The native Villano and tagged villain on this link is a villain one all the lands are allowed across

26
00:02:32,520 --> 00:02:33,960
the trunk.

27
00:02:33,960 --> 00:02:40,440
Now we can also use the command to show interfaces trunk that shows us a nice summary of information

28
00:02:40,770 --> 00:02:47,110
support to and Port three have been manually configured for trunking using editor one key.

29
00:02:47,460 --> 00:02:54,210
They are currently trunking the native villanelles villain one villans one to 4000 and 94 are permitted

30
00:02:54,510 --> 00:02:56,610
on those ports.

31
00:02:56,790 --> 00:03:02,130
The villains are allowed and active in the management domain of Elayne's one to two villans in the spending

32
00:03:02,130 --> 00:03:03,880
tree fording state and.

33
00:03:03,910 --> 00:03:08,460
0 zero to 1 and 2 and 3 is to.

34
00:03:08,620 --> 00:03:18,020
So we've configured switch one with these ports being access ports currently the PC isn't violent to

35
00:03:21,120 --> 00:03:30,510
and the PC is in villaine one now can rot a one ping Ratatouille and wrote a three and can rodded to

36
00:03:30,570 --> 00:03:39,840
ping any of those routers so you can write a one ton of debugging here ping 10 1 1 3.

37
00:03:40,560 --> 00:03:44,680
Yes it can kind of ping 10 1 1 4.

38
00:03:45,030 --> 00:03:46,590
Yes it can.

39
00:03:46,620 --> 00:03:51,640
This port allows VLAN 1 to traverse it using the untagged villaine.

40
00:03:51,750 --> 00:03:58,230
So the frame goes across this link as an untacked frame goes across the Slinky's and untagged frame

41
00:03:58,710 --> 00:04:05,160
and then goes across these two links as untagged switch to hasn't been configured for villans it using

42
00:04:05,160 --> 00:04:07,060
a default config.

43
00:04:07,650 --> 00:04:15,410
So show LAN brief on the switch shows that only Villon one exists on switch too.

44
00:04:15,450 --> 00:04:26,310
So let's put PC 4 into villaine 2 and let's see if PC 4 and PC 2 can ping each other sort of debugging

45
00:04:26,340 --> 00:04:30,570
on route to acting as our PC show Arpey interface brief.

46
00:04:30,810 --> 00:04:34,660
This PC has an IP address of ten at one to two to two.

47
00:04:35,010 --> 00:04:42,250
So give this one an IP address of 10 that won the 2.4 it's currently configured with this IP address

48
00:04:42,260 --> 00:04:43,660
so let's change that.

49
00:04:45,810 --> 00:04:47,220
Tended one or two to four

50
00:04:50,420 --> 00:04:59,160
ping ten that wanted to talk to what you'll notice is the pings file wrote a tune for cannot ping each

51
00:04:59,160 --> 00:05:00,120
other.

52
00:05:00,120 --> 00:05:01,860
And the question is why.

53
00:05:02,190 --> 00:05:04,730
Why can they not ping one another.

54
00:05:06,510 --> 00:05:13,170
Well the first problem is we haven't configured the land to on the switch switch to and we haven't put

55
00:05:13,230 --> 00:05:17,010
the port into villaine to switch to.

56
00:05:17,370 --> 00:05:24,470
I'm going to set it to VTB mode transparent so that we have to manually forget everything.

57
00:05:24,640 --> 00:05:27,840
Going to create relend to but notice please.

58
00:05:27,840 --> 00:05:32,400
Even though you create to the villain no ports are put into that villain by default.

59
00:05:32,400 --> 00:05:39,140
So show interface gigabit is 0 1 switch port that's the SID to face here.

60
00:05:40,000 --> 00:05:43,010
Shows me that that port is in Villon one.

61
00:05:43,570 --> 00:05:51,010
So what I need to do is go onto that port switchboard mode access to ensure that it's an access port

62
00:05:51,070 --> 00:05:53,870
that is the default switch port access.

63
00:05:54,020 --> 00:05:57,240
Learned to switch port No negotiate.

64
00:05:57,640 --> 00:06:03,520
Return of owner or to negotiations so that we have to manually configure everything and then explain

65
00:06:03,520 --> 00:06:04,390
how it works.

66
00:06:04,390 --> 00:06:08,420
So show interface gigabit 0 1 switch port.

67
00:06:09,630 --> 00:06:16,800
This port gigabit is one is enabled with using static access and Minister of moët and it's operating

68
00:06:16,800 --> 00:06:18,430
as a static access port.

69
00:06:18,560 --> 00:06:20,930
It's in Vigeland too at the moment.

70
00:06:21,090 --> 00:06:23,870
So all PC to be able to ping PC for.

71
00:06:24,540 --> 00:06:25,760
Let's do the ping again.

72
00:06:26,070 --> 00:06:30,330
Ping fails from router 4 or 2.

73
00:06:30,780 --> 00:06:33,640
And it also fails in the reverse direction.

74
00:06:33,690 --> 00:06:36,530
These two are not able to ping each other.

75
00:06:37,020 --> 00:06:42,000
Let's disable this port and force the traffic to go through the hub and then do a wide shot capture

76
00:06:42,000 --> 00:06:43,170
to see what's going on.
