Syntax
ip address ip-address { mask | mask-length } [ sub ]
undo ip address [ ip-address { mask | mask-length } [sub ] ]
View
VLAN interface view or LoopBack interface view
Parameter
ip-address: IP address of VLAN interface.
mask: Corresponding subnet mask.
mask-length: Mask length, i.e. the length of "1" in the IP address.
sub: the secondary IP address of the VLAN interface or LoopBack interface.
Description
Using ip address command, you can configure an IP address for VLAN interface or
LoopBack interface. Using undo ip address command, you can cancel an IP
address of the VLAN interface or LoopBack interface.
By default, all interfaces’ IP addresses are null.
Generally, it is enough to configure one IP address for an interface. You can also
configure eight IP addresses for an interface at most, so that it can be connected to
several subnets. Among these IP addresses, one is the primary IP address and all
others are secondary. The relationship between primary and secondary addresses is:
z When you configure a primary IP address for an interface, which already has a
primary IP address, the newly configured one will replace the old one.
z If you input undo ip address command without any parameter, the switch will
delete both primary and secondary IP address of an interface. undo ip address
ip-address { mask | mask-length } command can be used to delete the primary IP
address, while undo ip address ip-address { mask | mask-length } sub
command can be used to delete the secondary IP address.
