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

Add the network card resource to a group.

When you add the network card resource to a group, it will be immediately activated and displayed as online.

 

  1. 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.

  2. 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.

  4. Click on the 'Additional Settings' button to define attributes.

    Info

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

  5. Click the 'Finish' button to add the network card resource.
    You can immediately check the result in the management web console.

Deleting

Select Resource type → Right click → Delete Resource. 
The deleted resource will immediately disappear from the management web console.   

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.

DescriptionNote

Online

A network card is operating properly.

Offline

A network card resource cannot go offline.

 
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.

 

TroubleFault

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 resource cannot go offline.

 

...

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.

AdapterName

It is the ethernet adapter name registered in network interface card.

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.

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 ",".
