Make changes

To make changes, type configure terminal or conf t (shorthand)

Then, select an interface by typing in interface GigabitEthernet 0/2 or int Gi0/2 (shorthand)

Various VLAN config permutations

• Access port only
  • switchport access vlan <vlan>
  • switchport mode access
• Trunk mode
  • switchport trunk encapsulation dot1q
  • switchport mode trunk
  • Add or remove VLANs
    • switchport trunk allowed vlan add <vlan>
    • switchport trunk allowed vlan remove <vlan>
    • switchport trunk allowed vlan all
    • switchport trunk allowed vlan none
  • (if you want a native [untagged VLAN, PVID]) 
    • switchport trunk native vlan <vlan>

To make the changes persistent, type copy running-config startup-config or copy run start (shorthand).
