Parameters
ip-address: Specifies the IP address of the interface, in dotted decimal notation.

mask: Specifies the subnet mask in dotted decimal notation.
sub: Assigns a secondary IP address to the interface.
Usage guidelines
Use this command to configure a primary IP address for an interface. 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.
An interface can have only one primary IP address. A newly configured primary IP address overwrites
the previous address.
You cannot assign secondary IP addresses to an interface that obtains an IP address through BOOTP, or
DHCP.
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. Before removing the
primary IP address, remove all secondary IP addresses.
The primary and secondary IP addresses you assign to the interface can be located on the same network
segment, but different interfaces on your device must reside on different network segments.
