Managing Virtual Networks

You can view information about all the VMware vCenter servers managed by Network Director in the Manage Virtual Networks page. Network Director uses information from the virtual network to create an inventory view with a detailed list of all the elements in each virtual network. This includes the name of the vCenter server, the hostname or the IP address, ESXi version that is running on the vCenter server, the connection status, and the current orchestration mode.

While in Build mode with Virtual view selected, from the Tasks pane, click Manage Virtual Networks from Virtual Network Management menu to open the Manage Virtual Networks page. You can do the following from the Manage Virtual Networks page:

Modify Virtual Network Details

You can modify some of the details of an existing virtual network.

To modify credentials for a virtual network:

Select the virtual network that you want to modify and click Edit.
The Edit Virtual Network dialog box is displayed.

Modify the fields, as explained in Table 1.

Table 1: Modify Virtual Network Credentials Field Descriptions

Field	Description
Virtual Network Name/IP Address	Name or IP address of the host machine to be used as the VMWare vCenter server. This field cannot be modified.
Port	Port used for connection. The default value is 443. Note: You can modify this and specify a port of your choice. If you do so, make sure to manually change the Junos Space firewall settings to allow for this port.
Username	Username to be used to connect to the VMWare vCenter server.
Password	Password to be used with the name provided in the previous field.
Confirm password	Repeat the password provided in the previous field to confirm.

Click Modify to submit the changes that you made.

Configure Orchestration Mode

Orchestration applies aggregated VLAN configurations (including private VLAN) of the required port groups to the appropriate ports of the physical switch. Using Network Director, you can seamlessly orchestrate across physical and virtual network elements.

Each virtual switch can span across one or more hosts and is configured to have a minimum of one uplink port per host. A distributed virtual switch can span across multiple hosts, whereas a standalone virtual switch can be associated with only one host. A virtual switch comprises one or more port groups each of which is a collection of ports. Each of these ports can, in turn, be associated with a virtual machine or host kernel. Traffic coming from these ports is sent out of one of the uplink ports of the virtual switch, which is configured on the same host where the virtual machine or kernel resides.

Each physical NIC in a host is connected to an access port in the physical switch. Any configuration or restrictions that needs to be applied to the physical NIC to manage traffic is applied to the access port of the physical switch.

To set the orchestration mode operable on the virtual network:

Select a virtual network and click Configure Orchestration.
The Orchestration Mode dialog box is displayed.
Select if you want to enable or disable orchestration for the virtual network.
Note: When you select value, the description field displays a short description about your selection. We recommend that you read this carefully before making a choice.
Click OK to set the virtual network to the desired orchestration mode.
Network Director displays a message to indicate the successful modification of orchestration mode.

Network Director tracks the status of orchestration using an orchestration job. After an orchestration job is completed successfully, you must manually resynchronize the physical switch’s configuration with Network Director. If the system of record (SOR) mode set for the Junos Space Network Management Platform is:

Network as system of record (NSOR), then performing a resynchronization ensures that Junos Space automatically resynchronizes its configuration record to match the device configuration and sets the device configuration state to In Sync when the synchronization completes. For more details, see Resynchronizing Device Configuration.
Junos Space as system of record (SSOR), then you must perform a resynchronization and accept the out-of-band changes. Both the Junos Space configuration record and the Network Director Build mode configuration are resynchronized to reflect the out-of-band configuration changes. For more details, see Resynchronizing Device Configuration

Delete Virtual Networks

You can dissociate a virtual network from Network Director by deleting it from the system.

To delete a virtual network:

Select a virtual network and click Delete.
Network Director displays the Delete Virtual Network dialog box.
In the Delete Virtual Network dialog box, click Delete to delete the virtual network from Network Director.

Resynchronize Virtual Networks

You can resynchronize virtual networks registered with Network Director. During resynchronization, the vCenter configuration replaces the corresponding configuration available in Network Director. Any changes that you may have made to the vCenter using Network Director may be lost after a resynchronization.

Synchronization is run as a job and is managed by the Job Manager in Network Director.

To initiate resynchronizing:

Select a virtual networks and click Resynchronize.
The Status dialog box is displayed with the corresponding Job ID.
In the Job Information dialog box, click the job ID link.
The Job Details page displays details about the resynchronization job.
