CCNA Exploration LAN Switching and Wireless: VLANs

Lab 3.5.1: Basic VLAN Configuration

Learning Objectives
Upon completion of this lab, you will be able to: • • • • • • • • • • Cable a network according to the topology diagram Erase the startup configuration and reload a switch to the default state Perform basic configuration tasks on a switch Create VLANs Assign switch ports to a VLAN Add, move, and change ports Verify VLAN configuration Enable trunking on inter-switch connections Verify trunk configuration Save the VLAN configuration

Task 1: Prepare the Network
Step 1: Cable a network that is similar to the one in the topology diagram. You can use any current switch in your lab as long as it has the required interfaces shown in the topology. Note: If you use 2900 or 2950 switches, the outputs may appear different. Also, certain commands may be different or unavailable. Step 2: Clear any existing configurations on the switches, and initialize all ports in the shutdown state. If necessary, refer to Lab 2.5.1, Appendix 1, for the procedure to clear switch configurations. It is a good practice to disable any unused ports on the switches by putting them in shutdown. Disable all ports on the switches: Switch#config term Switch(config)#interface range fa0/1-24 Switch(config-if-range)#shutdown Switch(config-if-range)#interface range gi0/1-2 Switch(config-if-range)#shutdown

Task 2: Perform Basic Switch Configurations
Step 1: Configure the switches according to the following guidelines. • • • • • Configure the switch hostname. Disable DNS lookup. Configure an EXEC mode password of class. Configure a password of cisco for console connections. Configure a password of cisco for vty connections.

Step 2: Re-enable the user ports on S2 and S3. S2(config)#interface range fa0/6, fa0/11, fa0/18 S2(config-if-range)#switchport mode access

CCNA Exploration LAN Switching and Wireless: VLANs

Lab 3.5.1: Basic VLAN Configuration

S2(config-if-range)#no shutdown S3(config)#interface range fa0/6, fa0/11, fa0/18 S3(config-if-range)#switchport mode access S3(config-if-range)#no shutdown

Task 3: Configure and Activate Ethernet Interfaces
Step 1: Configure the PCs. You can complete this lab using only two PCs by simply changing the IP addressing for the two PCs specific to a test you want to conduct. For example, if you want to test connectivity between PC1 and PC2, then configure the IP addresses for those PCs by referring to the addressing table at the beginning of the lab. Alternatively, you can configure all six PCs with the IP addresses and default gateways.

Task 4: Configure VLANs on the Switch
Step 1: Create VLANs on switch S1. Use the vlan vlan-id command in global configuration mode to add a VLAN to switch S1. There are four VLANS configured for this lab: VLAN 10 (faculty/staff); VLAN 20 (students); VLAN...
