Configuring Standard VLANs on Catalyst Switches
Objective
The objective of this lab exercise is to learn and understand how to configure standard VLANs (1–1001) on Cisco Catalyst IOS Switches. Additionally, you will familiarize yourself with the commands available in Cisco IOS to validate and check your configurations.
Purpose
VLAN configuration is a fundamental skill. VLANs allow you to segment your network into multiple, smaller broadcast domains. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure VLANs on Cisco switches.
Lab Topology
Use the following topology to complete this lab exercise:
Task 1: Configure Hostname and VLANs
Objective: In preparation for VLAN configuration, configure a hostname on SW1 as well as the VLANs depicted in the topology.
Configuration Steps:
Switch#config t Enter configuration commands, one per line. End with CTRL/Z. Switch(config)#hostname SW1 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)#vlan 30 SW1(config-vlan)#name ENGINEERS SW1(config-vlan)#exit SW1(config)#vlan 40 SW1(config-vlan)#name SUPPORT SW1(config-vlan)#exit
Note: By default, Cisco switches are VTP servers, so no configuration is necessary for server mode. Use the show vtp status command to view the current VTP operating mode of the switch.

Task 2: Configure Access Ports and Assign VLANs
Objective: Configure ports FastEthernet0/5 to FastEthernet0/8 as access ports and assign them to the VLANs specified.
Configuration Steps:
SW1(config)#interface fastethernet0/5 SW1(config-if)#switchport mode access SW1(config-if)#switchport access vlan 10 SW1(config-if)#exit SW1(config)#interface fastethernet0/6 SW1(config-if)#switchport mode access SW1(config-if)#switchport access vlan 20 SW1(config-if)#exit SW1(config)#interface fastethernet0/7 SW1(config-if)#switchport mode access SW1(config-if)#switchport access vlan 30 SW1(config-if)#exit SW1(config)#interface fastethernet0/8 SW1(config-if)#switchport mode access SW1(config-if)#switchport access vlan 40 SW1(config-if)#end SW1#copy running-config startup-config
Task 3: Verify VLAN Configuration
Objective: Verify your VLAN configuration using relevant show commands in Cisco IOS.
Verification Commands:
SW1#show vlan brief
