View
VLAN interface view, loopback interface view, or console view
Parameter
ip-address: IP address of VLAN interface in dotted decimal format.
mask: Corresponding subnet mask in dotted decimal format.
mask-length: Mask length. That is, the number of bits with a value of 1.
sub: Specifies the IP address to be configured to be the secondary IP address of the
VLAN interface/loopback interface.
Description
Use the ip address command to assign an IP address and the corresponding subnet
mask to the VLAN interface/loopback interface/console interface.
Use the undo ip address command to remove the IP address and the corresponding
subnet mask assigned to the VLAN interface/loopback interface/console interface.
By default, a VLAN interface/loopback interface/console interface does not have an IP
address configured.
Normally, a VLAN interface/loopback interface/console interface only needs to be
configured with one IP address. But you can also assign up to 21 IP addresses to a
VLAN interface/loopback interface/console interface to enable it to connect to multiple
subnets. Of all the IP addresses assigned to a VLAN interface/loopback
interface/console interface, one is the primary IP address, and the other are secondary
IP addresses. The relationship between primary and secondary addresses is:
When you configure a primary IP address for an interface already has a primary IP
address configured, the newly configured one replaces the old one.
If you execute the undo ip address command without providing any parameter,
the switch removes both primary and secondary IP addresses of the interface. The
undo ip address [ ip-address { mask | mask-length } command can be used to
delete the primary IP address, while the undo ip address [ ip-address { mask |
mask-length } sub command can be used to delete the secondary IP address.
