Configuring an Interface as a Layer 2 Access Port

Note If you assign an interface to a VLAN that does not exist, the interface is not operational until you create
the VLAN in the VLAN database (see the
on page
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
vlan_num
Step 6
Switch(config-if)# no shutdown
Step 7
Switch(config-if)# end
Step 8
Switch# show running-config interface
{fastethernet | gigabitethernet} slot / port
Step 9
Switch# show interfaces [{fastethernet |
gigabitethernet | tengigabitethernet}
slot / port ] switchport
This example shows how to configure the Fast Ethernet interface 5/6 as an access port in VLAN 200:
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# interface fastethernet 5/6
Switch(config-if)# shutdown

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.
Place the interface in a VLAN.
Activates the interface. (Required only if you had shut down the
interface.)
Exits interface configuration mode.
Displays the running configuration of the interface.
Displays the switch port configuration of the interface.
End with CNTL/Z.
