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

mask: Subnet mask in dotted decimal notation.  

mask-length: Subnet mask length, the number of consecutive ones in the mask.  

sub: Secondary IP address for the interface. Currently, up to seven secondary IP addresses are 

supported on an interface. 

Use the ip address command to assign an IP address and mask to the interface.  

Use the undo ip address command to remove all IP addresses from the interface.  

Use the undo  ip  address  ip-address { mask | mask-length } command to remove the primary IP 

address.  

Use the undo ip address ip-address { mask | mask-length } sub command to remove a secondary IP 

address.  

By default, no IP address is assigned to any interface.  

When assigning IP addresses to an interface, consider the following:  

z 

You can assign only one primary IP address to an interface.  

z 

The primary and secondary IP addresses can be located in the same network segment.  

z 

Before removing the primary IP address, remove all secondary IP addresses.  

z 

You cannot assign a secondary IP address to the interface that is configured to obtain an IP 

address through DHCP.
