VLAN and VTP configuration

Lab instructions

The aim of this lab is to check your ability to configure VTP and VLAN on a small network of four switches. This lab will help you to prepare your ICND1 exam.
1.Configure the VTP-SERVER switch as a VTP server

2.Connect to the  3 other switches and configure them as VTP clients.
All links between swiches must be configured as trunk lines.

3.Configure VTP domain name as "TESTDOMAIN" and VTP password as "cisco"

4.Configure VLAN 10 with name "STUDENTS" and VLAN 50 with name "SERVERS"

5. Check propagation on all switches of the VTP domain.

Solution

Configure the VTP-SERVER switch as a VTP server
VTP-SERVER(config)#vtp mode server
Verify the VTP configuration using the "show vtp status command"
VTP-SERVER#show vtp status
VTP Version                     : 2
Configuration Revision          : 4
Maximum VLANs supported locally : 255
Number of existing VLANs        : 7
VTP Operating Mode              : Server
VTP Domain Name                 : TESTDOMAIN
VTP Pruning Mode                : Disabled
VTP V2 Mode                     : Disabled
VTP Traps Generation            : Disabled
MD5 digest                      : 0xAE 0x4F 0x3F 0xC5 0xD3 0x41 0x9C 0x11
Configuration last modified by 192.168.1.1 at 3-1-93 00:27:41
Local updater ID is 192.168.1.1 on interface Vl1 (lowest numbered VLAN interface found)


Connect to the  3 other switches and configure them as VTP clients.
All links between swiches must be configured as trunk lines.
VTP-CLIENT3(config)#vtp mode client
Verify the VTP configuration using the "show vtp status command"
VTP-CLIENT3#sh vtp status
VTP Version                     : 2
Configuration Revision          : 4
Maximum VLANs supported locally : 255
Number of existing VLANs        : 7
VTP Operating Mode              : Client
VTP Domain Name                 : TESTDOMAIN
VTP Pruning Mode                : Disabled
VTP V2 Mode                     : Disabled
VTP Traps Generation            : Disabled
MD5 digest                      : 0xAE 0x4F 0x3F 0xC5 0xD3 0x41 0x9C 0x11
Configuration last modified by 192.168.1.1 at 3-1-93 00:27:41


Configure VTP domain name as "TESTDOMAIN" and VTP password as "cisco"
1. Configure each link between switches as a trunk line
interface GigabitEthernet1/1
switchport mode trunk

interface GigabitEthernet1/2
switchport mode trunk

2.On the server :
VTP-SERVER(config)#vtp domain TESTDOMAIN
VTP-SERVER(config)#vtp password cisco

3.On each client :
VTP-CLIENT1(config)#vtp password cisco
VTP-CLIENT1(config)#vtp domain TESTDOMAIN


Configure VLAN 10 with name "STUDENTS" and VLAN 50 with name "SERVERS"
On the VTP server switch, configure the following commands
VTP-SERVER(config)#vlan 10
VTP-SERVER(config-vlan)#name STUDENTS
VTP-SERVER(config)#vlan 50
VTP-SERVER(config-vlan)#name SERVERS

Check propagation on all switches of the VTP domain.
Use the "show vlan brief" on each switch to check propagation of the 2 VLANS.
VTP-SERVER#show vlan brief

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
1    default                          active    Fa0/1, Fa0/2, Fa0/3, Fa0/4, [...]
10   STUDENTS                         active  
50   SERVERS                          active  
1002 fddi-default                     active  
1003 token-ring-default               active  
1004 fddinet-default                  active  
1005 trnet-default                    active
