Configuring VTP Clients and Servers on Cisco Catalyst Switches
Objective
The objective of this lab exercise is to learn and understand how to configure VTP server and client modes on Cisco Catalyst Switches. By default, all Cisco switches are VTP server devices.
Purpose
Configuring VTP client and server modes is a fundamental skill. VLANs are configured on VTP servers, and VTP clients receive VLAN information from the VTP servers in the same VTP domain. VLAN sharing is possible by using a trunk between the switches. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure VTP client and server modes.
Lab Topology
Use the following topology to complete this lab exercise:
Task 1: Configure Hostname and VLANs
Objective: Configure a hostname on the switches and routers as depicted in the topology. Note that the default mode of operation of Cisco Catalyst Switches is VTP server mode. Use a crossover cable between the switches.
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 Server and Client
Objective: Configure and verify SW1 as a VTP server switch and configure SW2 as a VTP client switch. Both switches should be in the VTP domain named CISCO.
Configuration Steps:
SW1#config t
Enter configuration commands, one per line. End with CTRL/Z.
SW1(config)#vtp domain CISCO
Changing VTP domain name from Null to CISCO
SW1(config)#
SW2#config t
Enter configuration commands, one per line. End with CTRL/Z.
SW2(config)#vtp mode client
Setting device to VTP CLIENT mode.
SW2(config)#vtp domain CISCO
Changing VTP domain name from Null to CISCO
SW2(config)#end
SW2#show vtp status

Task 3: Configure 802.1Q Trunk
Objective: Configure and verify FastEthernet0/1 between SW1 and SW2 as an 802.1Q trunk.
Verification Commands:
SW1#show int f0/1 switchport Name: Fa0/1 Switchport: Enabled Administrative Mode: dynamic auto Operational Mode: static access Administrative Trunking Encapsulation: dot1q Operational Trunking Encapsulation: native Negotiation of Trunking: On [Output Truncated] SW1#config t Enter configuration commands, one per line. End with CTRL/Z.

Task 4: Configure and Verify VLANs
Objective: Configure and verify VLANs 10 and 20 on SW1 with the names provided. Assign FastEthernet0/2 on both SW1 and SW2 to VLAN10. This interface should be configured as an access port.
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 20
SW1(config-vlan)#name MANAGERS
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
