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.

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.

Adding in Group

When add a resource from a group name, select a group -> right click -> 'Add Resource'. Or select Edit(E) from the main menu bar -> select 'Add Resource'. Or select 'Add Resource' icon from the tool bar.

[Figure] Adding Resource in a group
Select 'NIC' from Resource Type lists and click 'Next' button. When add a resource from the NIC resource type name, this step will be skipped.

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

Adding in Resource Type

ResourceType - Right Click - Click Add Resource

[Figure] Adding NIC Resource in a resource type
Enter resource name and select NIC.

[Figure] Add network card wizard view
Click on the 'Additional Settings' button to define attributes.

Additional setting can be selected as an option. You don't need to enter it.

[Figure] Additional Settings of network card wizard view
Click "Finish' button and network card resource is added.

State

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.

Status	Agent Command	Description
Online A network card is operating properly.	Offline	A network card resource cannot go offline.
Online A network card is operating properly.	Monitoring	It refers to the AdapterName attributes and checks the link status of the network device. A network card resource is deemed to be normal only if it a network device is connected.
Offline It is impossible to know the status of network card.	Online	A network card resource cannot go online.
	Monitoring	It refers to the AdapterName attributes and checks the link status of the network device. A network card resource is deemed to be normal only if it a network device is connected.
Trouble A device is not configured or a link is cut off. So, all the ICMP tests to the testing address failed.	Online	A network card resource cannot go online. (When trouble is recovered, it will automatically detect and switches to the online status. )
	Offline	A network card is a resource that cannot go offline.

*네트워크카드 리소스 특성

MCCS는 네트워크 장치에 온라인/오프라인 같은 명령을 내릴 수 없습니다. 네트워크 카드는 하드웨어적으로 설치됨과 동시에 운영체제에서 관리되기 때문입니다.
이런 특성 때문에 네트워크 카드는 리소스 타입의 Actions 속성값이 None이며, NoAction 값이 true 입니다.
이 속성 값은 리소스를 시작/종료 할 수 없고, 모든 노드에서 동시에 운용이 가능하며, 상태에 대한 감시만 한다는 것을 의미합니다. 이를 감지 전용 리소스라고 합니다.

Attribute

[Figure] Attribute of Network Interface Card

Attribute	Description	type	Default	Edit	Note
AdapterName	It is the ethernet adapter name registered in network interface card.	STRING		O
PingTimeout	It is the time limit for ping test. It goes through the test with the IP registered in TestAddressList and if there is no IP, it is ignored.	INTEGER	2sec	O
TestAddressList	It is the list of network access test address. If the ICMP test succeeds in at least one address, network connection state is considered normal. When there is more than one address, they are separated by ",".	IP ADDRESS		O

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.
For more information about resource type attribute, please refer to “6. Resource Type” for this document.
