ip address
Description
Use the ip address command to assign an IP address and subnet mask to a VLAN interface.
Use the undo ip address command 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 configuring 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.
To remove the primary IP address, use the undo ip address ip-address { mask | mask-length }
command.
To remove a secondary IP address, use the undo ip address [ ip-address { mask | mask-length } [
sub ] ] command
Related commands: display ip interface (Layer 3—IP Services Command Reference).

ip address ip-address { mask | mask-length } [ sub ]
undo ip address [ ip-address { mask | mask-length } [ sub ] ]
