Creating and managing superscopes

Creating and managing superscopes

A superscope is a container for IPv4 scopes in much the same way that an organizational unit is a container for Active Directory objects. Superscopes help you manage scopes available on the network by grouping them into a single point of management. For example, with a superscope, you can activate or deactivate multiple scopes through a single action. You can also view statistics for all scopes in the superscope rather than having to check statistics for each scope. Superscopes also support DHCP clients on a single physical network where multiple logical IP networks are used, or put another way, you can create superscopes to distribute IP addresses from different logical networks to the same physical network segment.

After you create at least one normal or multicast IPv4 scope, you can create a superscope by following these steps:

1. In the DHCP console, expand the node for the server with which you want to work, press and hold or right-click IPv4, and then tap or click New Superscope to start the New Superscope Wizard. Tap or click Next.

2. Enter a name for the superscope, and then tap or click Next.

3. Select scopes to add to the superscope. Select individual scopes by tapping or clicking their entry in the Available Scopes list. Select multiple scopes by tapping or clicking entries while holding down Shift or Ctrl.

4. Tap or click Next, and then tap or click Finish.

You can add scopes to a superscope when you create it, or you can add the scopes later. To add a scope to a superscope, follow these steps:

1. Press and hold or right-click the scope you want to add to a superscope, and then tap or click Add To Superscope.

2. In the Add Scope To A Superscope dialog box, select a superscope.

3. Tap or click OK. The scope is then added to the superscope.

To remove a scope from a superscope, follow these steps:

1. Press and hold or right-click the scope you want to remove from a superscope, and then tap or click Remove From Superscope.

2. Confirm the action by tapping or clicking Yes when prompted. If this is the last scope in the superscope, the superscope is deleted automatically.

When you activate or deactivate a superscope, you make all the scopes within the superscope active or inactive. To activate a superscope, press and hold or right-click the superscope, and then select Activate. To deactivate a superscope, press and hold or right-click the superscope, and then select Deactivate.

Deleting a superscope removes the superscope container but doesn’t delete the scopes it contains. If you want to delete the member scopes, you’ll need to do that separately. To delete a superscope, press and hold or right-click the superscope, and then select Delete. When prompted, tap or click Yes to confirm the action.
