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:
![Router Setup 1](/static/labs/cisco/CCNA_200-301/lab8/1.png)
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 VTP Version capable : 1 to 2 VTP version running : 1 VTP Domain Name : CISCO VTP Pruning Mode : Disabled VTP Traps Generation : Disabled Device ID : 0001.633A.3600 Configuration last modified by 0.0.0.0 at 0-0-00 00:00:00 Feature VLAN : -------------- VTP Operating Mode : Client 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.
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. SW1(config)#interface fastethernet0/1 SW1(config-if)#switchport mode trunk SW1(config-if)#end SW1#show interfaces trunk Port Mode Encapsulation Status Native vlan Fa0/1 on 802.1q trunking 1 Port Vlans allowed on trunk Fa0/1 1-1005 Port Vlans allowed and active in management domain Fa0/1 1 Port Vlans in spanning tree forwarding state and not pruned Fa0/1 none
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 SW1# 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 10 SALES active Fa0/2 20 MANAGERS active 1002 fddi-default active 1003 token-ring-default active 1004 fddinet-default active 1005 trnet-default active SW1#copy running-config startup-config SW2#config t Enter configuration commands, one per line.
