It monitors the physical network devices mounted in the system.
To obtain a network address, the network device resource should operate properly and it is also necessary to periodically monitor them.
To differentiate individual network devices in a system where multiple network cards are installed, we use the name registered in the MAC address or device driver, or the name registered in the network connection registration information.
A network card agent uses the name (FriendlyName) registered in the network connection registration information.
This name is a unique name that is familiar to a general user. It can be easily modified for user's convenience. The adapter name appearing in the 'Network Connection' screen, or the information displayed after 'Ethernet Adapter' when you run the 'ipconfig' command in the command prompt is the name used to identify a network card. The network interface card(NIC) resource defines this name by using the AdapterName attribute.

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 card agent: Manages the physical network adapters.

...

MCCS cannot use the online/offline commands to a network device. It is because a network is managed by the OS as soon as it is installed in the H/W.
Due to the characteristics, a network card's resource type action attribute is set to none. Also, its NoAction value is set to true.
The attribute value cannot be used to start or terminate the resource. It is operable at all nodes at the same time but it only monitors the status. It is called a monitoring only resource.
