You can use the following procedures to modify or delete a logical network in Virtual Machine Manager (VMM). For example, you may want to add or remove an associated network site, or modify an IP address pool.

Account requirements To complete this procedure, you must be a member of the Administrator or the Delegated Administrator user role.

To modify a logical network

1. Open the Fabric workspace.

2. In the Fabric pane, expand Networking, and then click Logical Networks.

3. On the Home tab, in the Show group, click Fabric Resources.

4. In the Logical Networks and IP Pools pane, do either of the following:

   1. To modify the logical network name or associated network sites, click the logical network that you want to modify. On the Home tab, in the Properties group, click Properties.

      On the Name tab, you can modify the name and the description, and starting with System Center 2012 SP1, the options. To modify the network sites, click the Network Site tab. To modify a network site, click the network site that you want to modify, and then change any associated settings. You can also add and remove network sites.

      Note

      You cannot remove a network site if it has a dependent resource, for example an associated static IP address pool.

   2. To modify an associated IP address pool, in the Logical Networks and IP Pools pane, expand the logical network, and then click the IP address pool. On the Home tab, in the Properties group, click Properties.

      You can modify the name, description, the IP address range, virtual IP (VIP) address reservations, the default gateway, Domain Name System (DNS) information, and Windows Internet Name Service (WINS) information. On the Inactive addresses tab, you can also release inactive IP addresses back to the static IP address pool.

      Note

      You can view but cannot modify network site information from the IP address pool properties. To modify network site information, open the properties of the logical network.

To delete a logical network

1. Open the Fabric workspace.

2. In the Fabric pane, expand Networking, and then click Logical Networks.

3. On the Home tab, in the Show group, click Fabric Resources.

4. In the Logical Networks and IP Pools pane, click the logical network that you want to delete.

5. On the Home tab, in the Dependencies group, click View Dependent Resources.

   The Show Dependencies dialog box lists any items that depend on the logical network. The list can include objects such as network sites (listed under Type as logical network definitions), load balancers, IP address pools, hosts, virtual machines, services, and templates. Before you can delete the logical network, you must modify or delete the dependent items so that they do not reference the logical network.

6. After you modify or remove all dependencies, with the logical network selected, on the Home tab, in the Remove group, click Remove.

7. In response to the confirmation message, click Yes to remove the logical network.
