7.1.1 Creating node groups

We begin by creating the node groups and then we add them to the node group maps.

Organization of this subsection

(1) Step 1: Creating the My Network node group

To create the My Network node group:

To create the Colorado node group, use the Filter Editor to establish a filter to select the nodes.

Reference note: When possible, use the Additional Filters tab rather than specifying a list of nodes using the Additional Nodes tab. Using a node group filter enables NNMi to automatically place a node into the correct node group as new nodes are added to the network.

Navigate to the Configuration workspace.
From Object Groups, select Node Groups.
Click the New icon.
In the Name attribute, enter Colorado.
Choose the Additional Filters tab.
Click OR to specify that you want NNMi to match a node if the node matches either of the host name values you enter.
In the Filter Editor's Attribute field, select hostname.
Selecting hostname specifies that NNMi match the host name values when determining whether a node belongs to this node group.
In the Operator field, select like.

Selecting like enables you to use wildcard characters in the search.
In the Value field, enter a value that represents the devices you want the node group to contain. For example, cisco*.ntc.example.com represents devices named ciscovalue.network-domain.
Click Append.
In the Attribute field, select hostname.
In the Operator field, select like.
In the Value field, enter a wildcard that represents the remaining device names you want to add to the Colorado node group.

For this example, use cisco?*.
Click Append.
Click Save to save the node group without closing the window.

To test the node group filter, you can view the members of the node group you just created.

From the Actions menu, choose Node Group Details, and then Show Members to launch a view containing all of the nodes in the node group.

Reference note: Examine the node group filter definition results until you are confident the node group filter is correct.

Establish a hierarchy for the node groups, starting with the top level node group, My Network.

In the Configuration workspace, select Object Groups, and then the Node Groups option to view a list of the node groups you created.
Navigate to the My Network node group, and then click Open.
Click the Child Node Groups tab.
Click the New icon.
In the Child Node Group attribute, click the Lookup icon and select Quick Find.

Important note

Use Quick Find to select an object, such as a node group, when it already exists.
Select USA as the child node group.
Click OK.
Click Save and Close to save your changes and close the Node Group Hierarchy form.
Click Save and Close to save your changes and close the Node Group form.

Establish Colorado as a child node group of the USA node group. Repeat the same steps described in (5) Step 5: Setting up the node group hierarchy for the My Network node group to make the Colorado node group a child of the USA Node Group.

You are ready to create the node group maps for the node groups that you created.
