To create a trunk port and allow VLAN 20 on a Cisco switch, you would need to perform the following three steps:
Example: switchport trunk encapsulation dot1q
Example: switchport mode trunk
Example: switchport trunk allowed vlan 20
Note: The "switchport trunk native vlan" command is used to specify the VLAN that is used for untagged traffic on the trunk port. It is not necessary for allowing a specific VLAN on the trunk port, but it can be used to ensure that untagged traffic is assigned to the correct VLAN.
