Add Network

Use the Add Network task to add a network definition to a cluster configuration.

Network 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".

Fields

Name:
Provide a unique name for the network on which the interface's IP labels/addresses will be bound.

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.

Network Type:

Select the network type from the list of available options.

Service IP address distribution preference
A distribution preference for service IP label aliases is a network-wide attribute used to control the placement of the service IP label aliases on the physical network interface cards on the nodes in the cluster.
Netmask (IPv4) /Prefix Length (IPv6):

Choose the netmask (configures an IPv4 network) or prefix length (configures an IPv6 network) for the network.

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.
