Parameters
ip-address : Specifies the IP address of the interface, in dotted decimal notation.
mask-length
: Specifies the subnet mask length in the range of 1 to 31. For a loopback interface,
the value range is 1 to 32.
mask : Specifies the subnet mask in dotted decimal notation.
sub
: Assigns a secondary IP address to the interface.
Usage guidelines
Use the command to assign a primary or secondary IP address to an interface.
An interface can have only one primary IP address. If you execute this command multiple times to
specify different primary IP addresses on an interface, the most recent configuration takes effect. If
the interface connects to multiple subnets, configure primary and secondary IP addresses on the
interface so the subnets can communicate with each other through the interface.
You cannot assign secondary IP addresses to an interface that obtains an IP address through
BOOTP IP unnumbered, or DHCP.
If you do not specify any parameters, the undo ip address command removes all IP addresses
from the interface. The
undo ip address ip-address { mask | mask-length }
command
removes the primary IP address. The
undo ip address ip-address { mask | mask-length }
sub
command removes a secondary IP address.
The primary and secondary IP addresses assigned to the interface can be located on the same
network segment. Different interfaces on your device must reside on different network segments.
Examples
# Assign VLAN-interface 10 a primary IP address 129.12.0.1 and a secondary IP address
202.38.160.1, with subnet masks both 255.255.255.0.
