Configuring an Interface as a Layer 2 Access Port

If you assign an interface to a VLAN that does not exist, the interface is not operational until you create

To configure an interface as a Layer 2 access port, perform this task:
Command
Step 1
Switch(config)# interface {fastethernet |
gigabitethernet | tengigabitethernet}
slot/port
Step 2
Switch(config-if)# shutdown
Step 3
Switch(config-if)# switchport
Step 4
Switch(config-if)# switchport mode access
Step 5
Switch(config-if)# switchport access vlan

Step 6
Switch(config-if)# no shutdown
Step 7
Switch(config-if)# end

Purpose
Specifies the interface to configure.
(Optional) Shuts down the interface to prevent traffic flow until
configuration is complete.
Configures the interface for Layer 2 switching:
• You must enter the switchport command once without any
keywords to configure the interface as a Layer 2 port before
you can enter additional switchport commands with
keywords.
Required only if you previously entered the no switchport
•
command for the interface.
Configures the interface as a Layer 2 access port.
Places the interface in a VLAN.
Activates the interface. (Required only if you had shut down the
