VLAN interface.
Use undo interface vlan-interface to remove the specified VLAN interface.
Create the VLAN before you create the VLAN interface.
To configure an IP address for a VLAN interface that will perform IP routing, use the ip address command
in VLAN interface view.

Description
Use ip address to assign an IP address and subnet mask to a VLAN interface.
Use undo ip address to remove the IP address and subnet mask for a VLAN interface.
By default, no IP address is assigned to any VLAN interface.
To connect a VLAN to multiple subnets, assign one primary IP address and multiple secondary IP
addresses to a VLAN interface.
When you configure IP addresses for a VLAN interface, follow these rules:
The primary IP address you assign to a VLAN interface overwrites the previous one, if any.
•
Remove all secondary IP addresses before you remove the primary IP address.
•
•
To remove all IP addresses, use the undo ip address command without any parameter.
