Introduction

In this tutorial, we will cover the configuration of access and trunk ports on a Cisco switch, as well as inter-VLAN routing using Switch Virtual Interfaces (SVIs) on a Layer 3 switch. This is part of the CCNA 200-301 course and will give you hands-on experience essential for your networking skills.

Step 1: Configure Access Ports

Access ports are used to connect end devices to a switch. Here’s how to set them up:

Enter Configuration Mode
- Access the switch console and enter privileged EXEC mode:
```
enable
configure terminal
```
Select the Interface
- Choose the interface you want to configure. For example, if you are configuring interface FastEthernet 0/1:
```
interface FastEthernet0/1
```
Set the Port to Access Mode
- Configure the interface as an access port:
```
switchport mode access
```
Assign the VLAN
- Assign the desired VLAN to the access port. For example, to assign VLAN 10:
```
switchport access vlan 10
```
Repeat for Additional Ports
- If you have more ports to configure, repeat steps 2 to 4 for each interface.

Step 2: Configure Trunk Ports

Trunk ports are used to carry traffic for multiple VLANs. Follow these steps for configuration:

Enter Configuration Mode
- Access the switch console and enter privileged EXEC mode:
```
enable
configure terminal
```
Select the Interface for Trunking
- Choose the interface you want to configure as a trunk. For example, if you are configuring interface FastEthernet 0/24:
```
interface FastEthernet0/24
```
Set the Port to Trunk Mode
- Configure the interface as a trunk port:
```
switchport mode trunk
```
Allow VLANs on the Trunk
- Specify which VLANs are allowed on the trunk. For example, to allow VLANs 10 and 20:
```
switchport trunk allowed vlan 10,20
```
Verify Configuration
- Use the following command to verify trunk configuration:
```
show interfaces trunk
```

Step 3: Configure Inter-VLAN Routing

Inter-VLAN routing allows communication between different VLANs using SVIs.

Enter Configuration Mode
- Access the switch console and enter privileged EXEC mode:
```
enable
configure terminal
```

Create SVIs for Each VLAN

For each VLAN, create a SVI and assign an IP address. For example, for VLAN 10:
```
interface vlan 10
ip address 192.168.10.1 255.255.255.0
no shutdown
```

Repeat for VLAN 20:

interface vlan 20
ip address 192.168.20.1 255.255.255.0
no shutdown

Enable Routing on the Switch
- If your switch supports it, enable IP routing:
```
ip routing
```
Verify SVI Configuration
- Check the configuration with:
```
show ip interface brief
```

Conclusion

In this tutorial, we covered the essential steps to configure access and trunk ports on a Cisco switch, as well as how to set up inter-VLAN routing using SVIs. These skills are crucial for managing VLANs in a network environment. For further practice, consider utilizing Packet Tracer labs or additional resources to solidify your understanding.
