Making the network topology visible to Network Operators

To enable Network Operators to view the discovered topology, add network views to the view collections that are associated with the users or user groups of the Operators.

A network discovery must have run, so that it is possible to view the generated topology. Also, the required users must have been created and assigned to the Network_Manager_User user group.

By default, the itnmadmin user has access to the the network topology through the Network Views. This is because Network Manager is configured to automatically deploy an initial network view that displays all the IP network entities on the network for a domain.

Unlike the itnmadmin user, newly-created users, for example Network Operators, do not have any access to the network topology through the Network Views. You must associate views of the network with the Operators' users or with their user groups. You do this in one of the following ways:

Creating new network views: Assign a new network view to a user or user group.
Copying existing network views: Copy a network view from the itnmadmin user and assign it to a user or user group.

The itnmadminuser has access to the network views that are assigned to each user and user group. For example, to access the network views of the user group Public, select Public Views. from the list. To access the views of a user called dlucas , select dlucas Views.

To copy a network view from the itnmadmin user to other user or groups:
1. Click the Incident icon and select Network Availability > Network Views.
2. From the list, select itnmadmin Views.
3. Click Copy or Move View .
4. Select Copy.
5. From the To list, select the network view collection to which to add the network view.
  Tip: To make the network view available to all users, select Global.
To create an initial network view that displays all the subnets on a domain:
1. Click the Incident icon and select Network Availability > Network Views.
2. From the list, select the network view collection for the required user or user group and click New View .
  Tip: To make the network view available to all users, select Global.
3. Type a name for the network view.
4. In the Parent list, select NONE.
5. In the Type list, select Dynamic Views - Subnet.
6. In the remaining fields, specify the layout and style, and the icons that represent the network view.
  The map icon is used to represent the network view in the right display panel, whereas the tree icon is used to represent the network view in the left navigation panel.
7. Click Filter.
8. Select the domain.
9. In the Subnet Classes field, select A & B or A, B & C.
  If you select A, B & C, a large number of subnets is created, because most networks contain large numbers of class C subnets.
10. Click OK.
To create an initial network view that displays all the entities on the network for a domain:
1. Click the Incident icon and select Network Availability > Network Views.
2. From the list, select the network view collection for the required user or user group and click New View .
  Tip: To make the network view available to all users, select Global.
3. Type a name for the network view.
4. In the Parent list, select NONE.
5. In the Type list, select Dynamic Views - Template.
6. In the remaining fields, specify the layout and style, and the icons that represent the network view.
  The map icon is used to represent the network view in the right display panel, whereas the tree icon is used to represent the network view in the left navigation panel.
7. Click Filter.
8. Select the domain.
9. In the Template field, select IP Default.
  
  Warning: Do not use the ip_default.xml template if you have large or very large networks. The ip_default.xml template is intended mainly for educational purposes to demonstrate how the topology can be displayed. Running this template against a large or very large production topology could have a serious impact on the memory and performance of your Network Manager installation, particularly on displaying and using network views. If you have large or very large networks, create network view templates that enable operators to generate a limited set of network views or create network views manually.
  For more information about creating network views and network view templates, see the following topics:
  
  How to create network view templates and make these templates available to operators

  For more information about network sizes, see Deployment scenarios.
10. Click OK.

When Network Operators log in with their users and open the Network Views, they can click the network views that you created or copied for them to begin visualizing the network.

To verify that the Operators can now display network views, select from the list a user or user group for which you have created or copied network views. For example, select Global if you created or copied network views for all users. The navigation tree now contains network views.

Alternatively, log out of Network Manager, and log back in as a user that now has network views assigned.

Now that the Operators have access to the topology, and can work, you can create additional network views that are designed around the access concept that you want to develop for the network. If you then want to revise Operators' access you can delete these initial network views.
