Here are some lab exercises for setting up VLANs on a basic switch:

**Topology**: You will need at least one Cisco switch for these exercises.

**Exercise 1: Creating VLANs**

1. Access the switch's CLI using a terminal emulator or console cable.
2. Enter privileged EXEC mode by typing `enable` and providing the enable password if configured.
3. Enter global configuration mode by typing `configure terminal`.
4. Create VLANs using the `vlan` command followed by the VLAN number:
   ```
   switch# configure terminal
   switch(config)# vlan 10
   switch(config-vlan)# name SALES
   switch(config-vlan)# exit
   switch(config)# vlan 20
   switch(config-vlan)# name MARKETING
   switch(config-vlan)# exit
   ```

**Exercise 2: Assigning Access Ports to VLANs**

1. Configure access ports and assign them to VLANs using the `interface` and `switchport access vlan` commands:
   ```
   switch(config)# interface fastethernet 0/1
   switch(config-if)# switchport mode access
   switch(config-if)# switchport access vlan 10
   switch(config-if)# exit

   switch(config)# interface fastethernet 0/2
   switch(config-if)# switchport mode access
   switch(config-if)# switchport access vlan 20
   switch(config-if)# exit
   ```

**Exercise 3: Verifying VLAN Configuration**

1. Verify the VLAN configuration using the `show vlan brief` command:
   ```
   switch# show vlan brief
   ```

**Exercise 4: Saving Configuration**

1. Save the configuration to the startup-config file using the `copy running-config startup-config` command:
   ```
   switch# copy running-config startup-config
   ```

**Exercise 5: Testing VLAN Configuration**

1. Connect devices to the configured access ports (e.g., computers or other switches).
2. Verify connectivity between devices within the same VLAN by attempting to ping each other.

These lab exercises cover the basics of setting up VLANs on a Cisco switch, including creating VLANs, assigning access ports to VLANs, verifying VLAN configuration, and saving the configuration. You can modify the VLAN numbers, names, and port assignments as needed for your specific environment.
