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.

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.)
