Use the Add Network task to add a network definition to a cluster configuration.
Networks in provide a way to logically group network interface cards, and a way to restrict placement of service addresses and persistent addresses. For example, networks can be used to make sure an application only uses adapters "A", "B", and "C", and not use adapters "X", "Y", and "Z".
Enter the value as 1-32 alphanumeric characters (letters [A-Z, a-z]), numbers [0-9] and underscores) in length. A name cannot begin with a number and a PowerHA™ reserved word cannot be a valid name.
Provide a netmask value as "X.X.X.X", where X is a number ranging from 0-255, or provide a prefix length value as numbers ranging from 1-128.
