It is managed IP address (virtual IP address) and subnet mask which will be assigned on a network interface card resource.
A real IP address which is static must be set in the network interface card to add on a virtual IP address.
This can be switchable node to node in case it reacts in the same manner as the node’s real IP address, and applications and other nodes can communicate with the node using the virtual IP address.
A virtual IP address cannot be used independently. This always depends on a network interface card resource, so this have a value which is name of the network interface card(NIC) resource in its ‘NICResName’ attribute. This value should be match to its depending NIC resource name to work properly.
If the NIC resource has not been configured or not in the ONLINE state, it cannot be used.

Adding

There are two way to add a resource which one is select this from a group name and another is select this from a resource type.

[Figure] Select Resource Wizard View
Next steps are same as adding in resource type.

ResourceType - Right Click - Click Add Resource

[Figure] Adding IP Resource in a resource type
Enter the resource name and select a virtual IP address and the NIC resource to use.

[Figure] Adding Network Address Wizard
Select the NIC resource and a virtual IP address. MCCS will suggest a possible resource name for you.

Status

The following table explains the status switching of the MCCS resource caused by a user's command and the status.
The command assumes that it is generated by a user.

Network address agent: Manages a virtual IP address.

Status	Agent command	Description
Online In this status, a virtual IP address is assigned to a network device.	Offline	An IP address assigned to the designated network card is removed.
	Monitoring	It tests if a virtual IP address exists on a network card.
Offline In this status, a virtual IP address is not assigned to a network device.	Online	It first checks if the designated network card is online or not. Before assigning an IP address, it first checks if other system is using that IP address. If it is not used by other systems, a virtual IP address is assigned to the network card. If it tries to go online with the address occupied by other system, it will be failed and it will enter the trouble state
	Monitoring	It tests if a virtual IP address exists on a network card.
Trouble 1. IP address assigned to a network device is removed by the external command. 2. A failure occurs in a network card. 3. You failed to assign a virtual IP address to a network device. (ex: For instance, other system is using the same IP address.) Specific causes can be found in the error log.	Online	Refer to the above online command.
	Offline	An IP address assigned to the designated network card is removed.

Attribute value of ArgList arguments are the values that are added resources and the value can be changed or viewed through 'Specified Attribute' list on the detailed information panel.
