1 00:00:09,330 --> 00:00:15,990 Now unfortunately the font of the switch is very small and doesn't wanna change I'll zoom in on the 2 00:00:15,990 --> 00:00:16,500 video. 3 00:00:18,030 --> 00:00:20,900 The core switch has a large font 4 00:00:21,240 --> 00:00:31,840 and even though I change the font via options, preferences, font and I've set it to a large number 5 00:00:35,550 --> 00:00:38,130 these 2960s I'm not changing their font. 6 00:00:39,370 --> 00:00:41,760 So I'll simply zoom in on the video. 7 00:00:41,760 --> 00:00:50,010 So my apologies if the resolution isn't that great when I configured these switches but on this access 8 00:00:50,010 --> 00:00:59,040 switch what we need to do is we need to configure interface gigabit 01 as a trunk port, so switch port 9 00:00:59,670 --> 00:01:11,430 mode trunk, that's come up but again don't forget that sometimes you have to specify the encapsulation. 10 00:01:11,820 --> 00:01:19,280 The switch doesn't allow you to specify the encapsulation it only supports dot1q so show interface 11 00:01:19,290 --> 00:01:19,850 gigabit 12 00:01:19,930 --> 00:01:30,200 01 switch port shows us that the encapsulation used is a dot1q. So that's the encapsulation 13 00:01:30,200 --> 00:01:38,490 that we're looking for the port is enabled and it's a trunk port. So show VLAN 14 00:01:38,820 --> 00:01:48,470 notice we're only seeing VLAN 1 in the VLAN database show VTP status shows us that the switch is a server 15 00:01:50,030 --> 00:02:00,760 number of VLANs in the VLAN database is 5 typically a switch would learn the VLANs from the 16 00:02:00,790 --> 00:02:02,020 core switch. 17 00:02:02,230 --> 00:02:13,320 So this port is a trunk port by default all VLANs will be permitted the switch is not learning the VLANs. 18 00:02:13,490 --> 00:02:22,810 Now if you wanna use VTP to distribute VLANs what you need to do is set the VTP domain. 19 00:02:23,180 --> 00:02:26,410 At the moment there is no domain name configured. 20 00:02:27,110 --> 00:02:35,640 So what we could do is say VTP domain and specify a domain such as CCNA. 21 00:02:35,830 --> 00:02:48,650 So now show VTP status shows us that the VTP domain name is CCNA, show VLAN shows us that we've got 22 00:02:48,680 --> 00:02:57,770 our VLANs in the VLAN database and then if we have a look on switch one, the access switch show VLAN 23 00:02:57,770 --> 00:03:05,570 shows that we still only have VLAN 1 and the other default VLAN on a real switch. 24 00:03:08,260 --> 00:03:12,690 The switch would learn and notice it has learnt that. 25 00:03:13,470 --> 00:03:14,590 So show VLAN 26 00:03:17,410 --> 00:03:20,600 and the switch in turn would learn the VLANs. 27 00:03:20,900 --> 00:03:22,700 So show VLAN here. 28 00:03:22,990 --> 00:03:30,270 We still have our VLANs in the VLAN database on this access switch hasn't learned the VLAN. 29 00:03:30,820 --> 00:03:34,480 I'll set the mode to VTP client to see if that makes it any better. 30 00:03:41,160 --> 00:03:46,250 I notice now it's learnt the VLANs. In the real world 31 00:03:46,280 --> 00:03:53,090 a switch would learn the VTP domain like packet tracer did here but a server would still synchronize 32 00:03:53,090 --> 00:04:01,000 with another server so the switch would have learnt the villains even if it hadn't been a client. In 33 00:04:01,000 --> 00:04:06,460 the exam they would be clearer about what to do with your VLANs so that would either tell you to 34 00:04:06,460 --> 00:04:15,670 create them manually or to use VTP to create the VLANs. So switch 1 has now learnt the VLANs. 35 00:04:15,970 --> 00:04:25,180 The next step is to go into forced Ethan at 0 1 and type switch port mode access switch port access 36 00:04:25,330 --> 00:04:37,070 VLAN in this case 10. Interface VLAN 1 the switch needs to have a IP address of 10.1. 37 00:04:37,070 --> 00:04:37,490 1 38 00:04:40,210 --> 00:04:47,590 .1 configured on it. I'll no shut the VLAN 39 00:04:47,590 --> 00:04:55,060 so at this point it will hopefully be able to ping the core switch in the topology which it can, 40 00:04:55,060 --> 00:04:57,090 so that's great. 41 00:04:57,430 --> 00:05:05,290 The last thing you need to do is specify default gateway of 10.1.1.254, so the switch 42 00:05:05,290 --> 00:05:12,100 should now be able to ping IP addresses in other VLAN on the core switch which it can. 43 00:05:13,210 --> 00:05:23,200 So again configuration was to set the VLAN to VLAN 10 on the access port we have to configure trunking 44 00:05:23,650 --> 00:05:32,200 on the link to the core we configured a SVI an IP address on the SVI and we configured a default gateway 45 00:05:32,860 --> 00:05:34,890 so that's switch 1 configured. 46 00:05:34,900 --> 00:05:38,470 Now we need to do something similar on switch 2 and switch 3.
