Cisco, how to assign an alias IP address to an interface
Problem:
Most router and server platforms allow one or more "alias" IP addresses assigned to each physical interface. However the Cisco alias commands do not seem to make much sense.
 
Solution:
The IOS "alias" command is used for something else. Set up alias IP addresses like this:

interface ethernet 0
ip address 192.168.1.1 255.255.255.0
ip address 192.168.2.1 255.255.255.0 secondary
!
