ip address
ip-address { mask | mask-length } [ sub ]
undo ip address [ ip-address { mask | mask-length } [ sub ] ]
View
VLAN interface view, loopback interface
view
Parameter
ip-address:
IP address, in dotted decimal notation.
mask: Subnet
mask, in dotted decimal notation.
mask-length:
Length of a subnet mask.
sub:
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, a VLAN or loopback interface has
no IP address.
Generally, it is enough to configure one IP
address for a VLAN/LoopBack interface. However, you can configure up to eight
IP addresses for a VLAN/LoopBack interface so that it can be connected to
several subnets. Among these IP addresses, one is the primary IP address and
all the others are secondary ones. The relationship between the primary address
and the secondary addresses is as follows:
l
When you configure a primary IP address for an
interface which already has a primary IP address, the new address will replace
the old one.
l
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 secondary IP addresses.
Related command: display ip interface.

# Specify the IP address and subnet mask of
VLAN interface 1 as 129.12.0.1 and 255.255.255.0 respectively.
