The vDC Network detail page displays:
  • Status – the vDC network status condition (e.g., "Ready").

  • Gateway – the vDC network's gateway IP address. The gateway address is the IP address serving as a point of contact from within the network to other networks or the internet.

  • Netmask – a 32-bit subnet mask used to divide an IP address into subnets and specify the network's available hosts. The netmask determines the number of IP addresses that are contained within the network identified by the Gateway address. Navisite Cloud Director network masks are always 255.255.255.0, which results in networks with 254 usable IP addresses.

  • Current Status – vDataCenter network status information, including:

    • vDC Network Diagram – Clicking objects in the vDC network diagram provides pop-up summaries for Edge Gateways, vDC Networks, and vApps, which in turn link to further detail screens.

      The Legend button provides a summary key to the images in the diagram.

      The diagram's vApp icon includes symbols indicating power state (running, stopped, partially running) of virtual machines (VMs) within the vApp.

    • Task History – Displays a subset of system task history, relating to actions taken on the vDC network's configuration. See How do I monitor my tasks? for more information.

    •  

  • IP Allocation – vDataCenter internet protocol (IP) address allocation information, including:

    • IP Addressing – allows you to add Dynamic Host Configuration Protocol (DHCP) and Static IP address ranges to the vDC network, and view, edit, or delete currently assigned IP address ranges.

      The graph in the "IP Addressing" section represents allocated IP address ranges with a colored bar. Hover the mouse cursor over the bar to view details on existing static (green bar) and DHCP (blue bar) range allocation and usage.

      Enabling/Disabling DHCP
      DHCP is a protocol that is commonly used to dynamically assign IP addresses. When virtual machines (VMs) on the network are powered on, they are assigned an IP address from a pool of addresses reserved specifically for DHCP.

      To enable or disable DHCP for the vDC network, click the "gear" icon to the right of the "DHCP Enabled" field at the top of the "IP Addressing" section, select Yes or No from the drop-down menu, and click the green check mark button.

      Adding IP Ranges
      To add a new static or DHCP IP address range to the network:

      1. Click the desired unallocated area in the graph, and select Add DHCP range here or Add static IP range here, as desired. A new entry is added to the IP address range table below the graph, and can be defined as necessary.

      OR

      1. Click +Add DHCP Range or +Add Static IP Range below the graph. A new entry is added to the IP address range table below the graph, and can be defined as necessary.

      2. In the "Range" column of the newly added IP address range table entry, define the starting and ending IP addresses in the new address range.

        A DHCP IP range cannot overlap with any other DHCP ranges, or with a static IP range.

        A static IP range cannot overlap with a DHCP IP range. A new static IP range that is adjacent to an existing range will be combined with the existing range.

      3. Click the green check mark button to complete the definition.

      Specifying DHCP Range Lease Times
      To specify the default time period for which a client can request and hold a lease on an IP address in a DHCP range, click the "gear" icon in the "Default Lease" column for the DHCP range, enter the desired amount of time (in seconds) in the resulting field, and click the green check mark button.

      To specify the maximum time period for which a client can request and hold a lease on an IP address in a DHCP range, click the "gear" icon in the "Max Lease" column for the DHCP range, enter the desired amount of time (in seconds) in the resulting field, and click the green check mark button.

      Editing IP Ranges
      To change the IP address range for an existing definition, click the "gear" icon to the right of the address range value in the "Range" column, enter the IP addresses in the range as desired, and click the green check mark button to complete the definition.

      Deleting IP Ranges
      To delete an existing IP address range in the table, click Delete for the desired table entry. A confirmation pop-up window appears. To complete the deletion, click Delete IP range (for a static range) or Delete DHCP range in the pop-up window.

    • Allocated IPs – presents a tabular display of IP addresses allocated in the vDC network. Links in the "Using this IP" and "vApp" columns allow you to view detail pages for the associated networks, vApps, and VMs.



  • vDataCenter network Configuration information, including:

    • Network Config – provides the following information about the vDC network:

      Connection – A network's connection is a parent network or device to which it is connected to provide an external connection or additional network services. For example, a vDC network can be connected to an edge gateway network (automatically provisioned as part of your account) in order to access to the internet.

      Primary DNS – the IP address of the vDC network's primary domain name server (DNS). The DNS maintains a directory of domain names and translates them to IP addresses. To change the primary DNS address, click the "pencil" icon to the right of the displayed address, enter the desired address (in x.x.x.x IP notation format), and click the green check mark button.

      Secondary DNS – the IP address of the vDC network's secondary (backup) DNS. To change the secondary DNS address, click the "pencil" icon to the right of the displayed address, enter the desired address (in x.x.x.x IP notation format), and click the green check mark button.

      DNS Suffix – the Domain Name Server (DNS) suffix for VMs on the vDC network. The DNS suffix is used in DNS name registration and DNS name resolution (e.g., yourdomain.com). If the DNS suffix is not configured, the DNS name of the local active directory (AD) is used. To set or change the DNS suffix, click the "pencil" icon to the right of the "DNS Suffix" field, enter the desired DNS suffix (e.g., yourdomain.com), and click the green check mark button.

    • Object Properties – the "Object Properties" section provides the vDC network's Description, vCloud, vDataCenter, and Universally Unique Identifier (UUID) values.

      Description – the vDC network's description. To change the description, click the "pencil" icon to the right of the displayed description, enter the desired description, and click the green check mark button.

Downloading Table Data

To download any displayed table data as a .csv file, click the "Download" icon above the table.
 

Adding Tags to a vDC Network

Tags are keywords that you can use to identify or logically group items. They are useful in finding items through the universal search or a table’s filter.

Click the Add Tag button at the top of the vDC Network detail page to add a tag to the vDC network item.

See What is a Tag? and How do I add or delete Tags? for more information.

Viewing the vDC Network in vCloud Director

Click the View in vCloud button at the top of the vDC Network detail page to launch VMware vCloud Director® and use the interface to view the vDC network. See View in vCloud for more information.

Deleting the vDC Network

The Delete button at the top of the vDC Network detail page allows you to delete the vDC network from your Navisite Cloud Director environment.

Note: A vDC network can be deleted only after all of its connected vApps and VMs have been deleted. Once any connected vApps and VMs have been deleted, the vDC Network detail page's Delete button becomes active and available for use.

Click Delete at the top of the vDC Network detail page to delete the vDC network, and click OK to confirm the deletion.
