DHCP Server Profile

Dynamic Host Configuration Protocol (DHCP) automates network-parameter assignment to network devices from one or more DHCP servers. When a DHCP-configured client connects to a network, the DHCP client sends a broadcast query requesting necessary information from a DHCP server. The DHCP server manages a pool of IP addresses and information about client configuration parameters such as default gateway, domain name, servers, and so on.

On receiving a valid request, the server assigns the computer an IP address, a lease (length of time the allocation is valid), and other IP configuration parameters, such as the subnet mask and the default gateway. The query is typically initiated immediately after booting, and must be complete before the client can initiate IP-based communication with other hosts. During initialization, network clients try to dynamically obtain their IP addresses. In small networks, where all the systems are in the same IP subnet, the client and the server can communicate directly.

Creating a DHCP Server Profile

To create a DHCP Server profile, complete the following steps:

  1. In the HPE Aruba Networking Central landing page, click the configurationicon.
    The Profiles tab is displayed.

  2. In the left navigation menu, select one of the following options:

    • Library—The default selection. If you create profiles in the Library, then you must assign scope and device functions to the profiles. For more information, see Assigning Scope to a DHCP Server Profile.

    • Global—If you create profiles at the Global level, then the profiles have Global scope assigned by default.

    • Site Collections—If you create profiles at the Site Collections level, then the profiles have site collection scope assigned by default.

    • Sites—If you create profiles at the Site level, then the profiles have site scope assigned by default.

    • Devices—If you create profiles at the Device level, then the profiles have device scope assigned by default.

    • Device Groups—If you create profiles at the Device Group level, then the profiles have device group scope assigned by default.

    Note:

    • To create profiles at the Global level, select the device type from the Device Function drop-down list before step 4.
    • To create profiles at the Site Collections, Sites, Devices, and Device Group level, complete the following steps before step 4:
      1. Select Site Collection, Site, Device, or Device Group in the left navigation menu.
      2. Select a Site Collection, Site, Device, or Device Group from the list view depending on the level where you are creating the profile.
      3. Select the device type from the Device Function drop-down list.

  3. On the Network Services card, click DHCP Server.
    Alternatively, you can complete the following steps:

    1. On the Network Services card, click Manage.

    2. On the DHCP Server card, click Manage.

    The DHCP Server list view is displayed.

  4. Click Create Profile.
    The Create Profile side panel is displayed.

  5. Enter the DHCP Server profile parameters:

    • Create as a local profile—Select this checkbox if you want to configure this profile as local.

      Note:

      The Create as a local profile checkbox is available at the Global, Site Collections, Sites, Devices, and Device Groups levels. It is not available at the Library level.

    • Name—Enter the name of the DHCP Server profile.

    • Description—Enter the description for the DHCP Server profile

  6. Configure the DHCP Server profile instance as follows:

    • To configure an IPv4 DHCP Server profile, click the add icon in the IPv4 DHCP Server section.

      The Add server instance side panel is displayed.

      1. Configure the following parameters:

        • Configure this server as AOS CX only—Select this checkbox to configure the DHCP server instance as AOS-CX only. If selected, the VRF drop-down menu is displayed.

        • VRF—Select a default or configured VRF profile from the drop-down menu.

        • DHCP Pool—Select a default or configured DHCP pool profile from the drop-down menu.

        • Authoritative—Select this checkbox to configure the DHCP Server profile instance as authoritative on the current VRF.

        • Enable—Select this checkbox to enable the DHCP Server profile instance.

      2. Click Add.

    • To configure an IPv6 DHCP Server profile, select the Enable IPv6 DHCP Server check box and then click the add icon in the IPv6 DHCP Server section.

      The Add server instance side panel is displayed.

      1. Configure the following parameters:

        • VRF—Select a default or configured VRF profile from the drop-down menu.

        • DHCP Pool—Select a default or configured DHCP pool profile from the drop-down menu.

        • Authoritative—Select this checkbox to configure the DHCP Server profile instance as authoritative on the current VRF.

        • Enable—Select this checkbox to enable the DHCP Server profile instance.

      2. Click Add.

  7. Click Create.

  8. To delete a profile, hover over the profile row, and click the delete icon.

  9. To search for a profile, type the profile name in the search bar.

    The search bar displays dynamic results as soon as you start typing.

Note:

You can only create a single DHCP server profile within the same scope.

Gateways are compatible only with the IPv4 DHCP Server profile.

Assigning Scope to a DHCP Server Profile

You must assign a scope and device function to a DHCP Server profile created in the Library.

To assign scope to a profile, complete the following steps:

  1. In the HPE Aruba Networking Central landing page, click the configurationicon.
    The Profiles tab is displayed.

  2. Ensure that the default option Library is selected in the left navigation menu.

  3. On the Network Services card, click DHCP Server.
    Alternatively, you can complete the following steps:

    1. On the Network Services card, click Manage.

    2. On the DHCP Server card, click Manage.

    The DHCP Server list view is displayed.

  4. Hover on the profile to which you want to assign a scope and click the Ellipsis icon.

  5. Select Assign.

    The Assign Profile side panel is displayed.

  6. Select the device types from Device Function list.

  7. To add a scope, click the Add icon on the Scopes table.

  8. Select a scope from the following Scope Level options in the drop-down list.

    • Global—Selecting this option assigns the scope at the Global level.

    • Site Collections—Select the site collections from the Assign to Scope drop-down list.
