ip address

Syntax
ip address ip-address { mask | mask-length } [ sub ]
undo ip address [ ip-address { mask | mask-length } [ sub ] ]
View
VLAN interface view, loopback interface view
Parameters
ip-address: IP address, in dotted decimal notation.
mask: Subnet mask, in dotted decimal notation.
mask-length: Subnet mask length, the number of consecutive ones in the mask. It is in the range of 0 to
32.
sub: Specifies a secondary IP address of a VLAN or loopback interface.
Description
Use the ip address command to specify an IP address and mask for a VLAN or loopback interface.
Use the undo ip address command to remove an IP address and mask of a VLAN or loopback
interface.
By default, no IP address is configured for VLAN or loopback interface.
Note that:
If you execute the undo ip address command without any parameter, the switch deletes both
primary and secondary IP addresses of the interface.
The undo ip address ip-address { mask | mask-length } command is used to delete the primary IP
address.
The undo ip address ip-address { mask | mask-length } sub command is used to delete specified
secondary IP addresses.
You can assign at most five IP address to an interface, among which one is the primary IP address
and the others are secondary IP addresses. A newly specified primary IP address overwrites the
previous one if there is any.
The primary and secondary IP addresses of an interface cannot reside on the same network
segment; the IP address of a VLAN interface must not be in the same network segment as that of a
loopback interface on a device.
A VLAN interface cannot be configured with a secondary IP address if the interface has been
configured to obtain an IP address through BOOTP or DHCP.
