Configuring VTP Transparent Mode on Cisco Catalyst Switches
Objective
The objective of this lab exercise is to learn and understand how to configure VTP Transparent mode on Cisco Catalyst Switches. By default, all Cisco switches are VTP server devices.
Purpose
Configuring VTP Transparent mode is a fundamental skill. VLANs configured on a switch in VTP Transparent mode are not automatically propagated to other switches within the same VTP domain as they would be by a VTP server. Switches configured in VTP Transparent mode use a trunk to forward traffic for configured VLANs to other switches. As a Cisco engineer, and for the Cisco CCNA exam, you will be expected to know how to configure VTP Transparent mode.
Lab Topology
Use the following topology to complete this lab exercise:
![Router Setup 1](/static/labs/cisco/CCNA_200-301/lab9/1.png)
Task 1: Configure Hostname
Objective: Configure a hostname on switches 1 and 2 and routers 1 and 3 as illustrated in the topology.
Configuration Steps:
Switch#config t Enter configuration commands, one per line. End with CTRL/Z. Switch(config)#hostname SW1 SW1(config)# Switch#config t Enter configuration commands, one per line. End with CTRL/Z. Switch(config)#hostname SW2 SW2(config)# Router#config t Enter configuration commands, one per line. End with CTRL/Z. Router(config)#hostname R1 R1(config)# Router#config t Enter configuration commands, one per line. End with CTRL/Z. Router(config)#hostname R3 R3(config)#
Task 2: Configure VTP Transparent Mode
Objective: Configure and verify SW1 and SW2 in VTP Transparent mode. Both switches should be in the VTP domain named CISCO. Switches must be in the same VTP domain to share VLAN information via a trunk.
Configuration Steps:
SW1#config t Enter configuration commands, one per line. End with CTRL/Z. SW1(config)#vtp mode transparent Setting device to VTP TRANSPARENT mode. SW1(config)#vtp domain CISCO Changing VTP domain name from NULL to CISCO SW1(config)#end SW1#show vtp status VTP Version capable : 1 to 2 VTP version running : 1 VTP Domain Name : CISCO VTP Pruning Mode : Disabled VTP Traps Generation : Disabled Device ID : 00D0.9774.C300 Configuration last modified by 0.0.0.0 at 0-0-00 00:00:00 Feature VLAN : -------------- VTP Operating Mode : Transparent Maximum VLANs supported locally : 255 Number of existing VLANs : 5 Configuration Revision : 0 MD5 digest : 0x1A 0xFC 0x64 0xDA 0x8E 0xA1 0x8A 0x3B 0x47 0x97 0x87 0xB1 0x8B 0x59 0xE9 0x52 SW2#config t Enter configuration commands, one per line. End with CTRL/Z. SW2(config)#vtp mode transparent Setting device to VTP TRANSPARENT mode. SW2(config)#vtp domain CISCO Changing VTP domain name from NULL to CISCO SW2(config)#end SW2#show vtp status VTP Version capable : 1 to 2 VTP version running : 1 VTP Domain Name : CISCO VTP Pruning Mode : Disabled VTP Traps Generation : Disabled Device ID : 00E0.8FAE.5400 Configuration last modified by 0.0.0.0 at 0-0-00 00:00:00 Feature VLAN : -------------- VTP Operating Mode : Transparent Maximum VLANs supported locally : 255 Number of existing VLANs : 5 Configuration Revision : 0 MD5 digest : 0x1A 0xFC 0x64 0xDA 0x8E 0xA1 0x8A 0x3B 0x47 0x97 0x87 0xB1 0x8B 0x59 0xE9 0x52
Task 3: Configure 802.1Q Trunk
Objective: Configure and verify FastEthernet0/1 between SW1 and SW2 as an 802.1Q trunk.
Note: Some Cisco switches default to 802.1Q trunking, but this is not the case for the 2960 Switch used in the exam.
Verification Commands:
SW1#config t Enter configuration commands, one per line. End with CTRL/Z. SW1(config)#interface fastethernet0/1 SW1(config-if)#switchport mode trunk SW2#config t Enter configuration commands, one per line. End with CTRL/Z. SW2(config)#interface fastethernet0/1 SW2(config-if)#switchport mode trunk
Task 4: Configure and Verify VLANs
Objective: Configure and verify VLANs 10 and 30 on SW1 with the provided names. Assign FastEthernet0/2 on SW1 to VLAN 10 as an access port. Configure and verify VLANs 10 and 40 on SW2 with the provided names. Assign FastEthernet0/2 on SW2 to VLAN 10 as an access port.
Verification Commands:
SW1#config t Enter configuration commands, one per line. End with CTRL/Z. SW1(config)#vlan 10 SW1(config-vlan)#name SALES SW1(config-vlan)#exit SW1(config)#vlan 30 SW1(config-vlan)#name MANAGEMENT SW1(config-vlan)#exit SW1(config)#interface fastethernet0/2 SW1(config-if)#switchport mode access SW1(config-if)#switchport access vlan 10 SW1(config-if)#end SW1#show vlan brief VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Fa0/3, Fa0/4, Fa0/5, Fa0/6 Fa0/7, Fa0/8, Fa0/9, Fa0/10 Fa0/11, Fa0/12, Fa0/13, Fa0/14 Fa0/15, Fa0/16, Fa0/17, Fa0/18 Fa0/19, Fa0/20, Fa0/21, Fa0/22 Fa0/23, Fa0/24, Gig0/1, Gig0/2 1002 fddi-default active 1003 token-ring-default active 1004 fddinet-default active 1005 trnet-default active 10 SALES active Fa0/2 30 MANAGEMENT active SW1#copy running-config startup-config SW2#config t Enter configuration commands, one per line. End with CTRL/Z.

Note: Default switches configured for VTP Transparent mode do not exchange VLAN information. You can see in the output above that VLAN 30 on SW1 is not propagated to SW2, and VLAN 40 on SW2 is not propagated to SW1. In Transparent mode, all VLANs must be manually configured on all switches.
Task 5: Configure and Verify IP Addresses
Objective: Configure R1 and R3 FastEthernet interfaces with the IP addresses 10.0.0.1/28 and 10.0.0.3/28, respectively. Test VLAN connectivity by pinging between R1 and R3.
Verification Commands:
R1#config t Enter configuration commands, one per line. End with CTRL/Z. R1(config)#interface fastethernet0/0 R1(config-if)#ip address 10.0.0.1 255.255.255.240 R1(config-if)#no shutdown R1(config-if)#end R1#copy running-config startup-config R3#config t Enter configuration commands, one per line. End with CTRL/Z. R3(config)#interface fastethernet0/0 R3(config-if)#ip address 10.0.0.3 255.255.255.240 R3(config-if)#no shutdown R3(config-if)#end R3#copy running-config startup-config R1#show ip interface brief Interface IP-Address OK?
