You can create several network templates in the IP Space tab, but you can only assign one template to a network.

To create a network template:

  1. Select the IP Space tab. Tabs remember the page you last worked on, so select the tab again to ensure you're on the Configuration information page.
  2. From the configuration drop-down menu, select a configuration.
  3. Under IPv4 Network Templates, click New.
  4. Select Network Template.
  5. Under General, set the name for the network template and determine the location of the network gateway:
    • Name—enter a name for the network template.
    • Gateway Offset—enter a value for the position of the network gateway. Select from start or from end to offset the gateway from the start or end of the network.
  6. Under Network Structure, define reserved addresses, DHCP range, or IP group settings. Click the New button and then use these fields to create a network structure:
    Note: IP addresses included in different types of network structures cannot be overlapped. Overlapping IP addresses in different network structures will cause an error.
    • Type—select Reserved Addresses, DHCP Range, or IP Group. If you select DHCP Range, you can select Split DHCP range around static, reserved and gateway addresses to split the DHCP range.
    • Defined By—select the type of method that will be used to create a DHCP range. This field will only be available when DHCP Range is selected. Depending on the method selected, different values are required in the Offset/Start Offset and Size/End Offset fields.
    • Direction—select from start or from end to offset the reserved addresses or DHCP range from the start or end of the network. When you select from start, the offset is counted from the start of the network and the reserved addresses or DHCP range is counted forward. When you select from end, the offset is counted from the end of the network, and the reserved addresses or DHCP range is counted backward.
      Two examples:
      • In the network 192.0.1.0/24, selecting from start and setting Offset to 10 and Size to 10 creates a range of 10 addresses beginning at 192.0.1.10 and counting forward to 192.0.1.19.
      • In the network 192.0.1.0/24, selecting from end and setting Offset to 10 and Size to 10 creates a range of 10 addresses beginning at 192.0.1.245 and counting backward to 192.0.1.236.
    • Offset/Start Offset—enter a value for the starting position of the address block or DHCP range.
    • Size/End Offset—for Reserved Addresses and IP Group types, enter a value for the number of addresses in the address block. For DHCP Range, if you select Offsets, enter a value for the ending position of the DHCP range. If you select Offsets and Size, enter a set value for the size of the DHCP range. If you select Offsets and Percentage, enter a value for the size of the DHCP range in proportion to the parent network size. For example, the value 20 represents 20% of the parent network size.
    • Name—type a descriptive name to describe the purpose of the block. The Name field is mandatory for the IP group type.
    Network templates can also contain deployment options, including DHCP Client, DHCP Service, DHCP Vendor, DHCPv4 Raw, DNS Raw, and DNS options, as well as a Start of Authority setting. After creating a network template, click the template’s Deployment Options tab to set these options in the template.
    Note: A conflict between a network and a template occurs when the network and template have the same deployment option server settings and you perform the following:
    • Add a deployment option to the template and the following are true:
      • The option already exists in the network
      • The values of the option added to the template are different from the values of the option in the network
    • Add a deployment option to the network and the following are true:
      • The option already exists in the template
      • The values of the option added to the network are different from the values of the option in the template
    • After applying a template to a network, you change deployment option settings in the network

    If the deployment option server settings of the network and template are different, a conflict does not occur.

  7. Click Add. To create another network template, click Add Next.
