Configuring VLAN Interfaces
– 402 –
interface vlan This command enters interface configuration mode for VLANs, which is used to
configure VLAN parameters for a physical interface. Use the no form to change a
Layer 3 normal VLAN back to a Layer 2 interface.
Syntax
[no] interface vlan vlan-id
vlan-id - ID of the configured VLAN. (Range: 1-4093)
Default Setting
None
Command Mode
Global Configuration
Command Usage
◆ Creating a “normal” VLAN with the vlan command initializes it as a Layer 2
interface. To change it to a Layer 3 interface, use the interface command to
enter interface configuration for the desired VLAN, enter any Layer 3
configuration commands, and save the configuration settings.
◆ To change a Layer 3 normal VLAN back to a Layer 2 VLAN, use the no interface
command.
Example
The following example shows how to set the interface configuration mode to
VLAN 1, and then assign an IP address to the VLAN:
Console(config)#interface vlan 1
Console(config-if)#ip address 192.168.1.254 255.255.255.0
Console(config-if)#
