Use the vCloud Director tenant portal to configure the IP pools needed for a DHCP service of an advanced edge gateway. DHCP automates IP address assignment to virtual machines connected to organization virtual data center networks.

As described in the NSX Administration documentation, the DHCP service requires a pool of IP addresses. An IP pool is a sequential range of IP addresses within the network. Virtual machines protected by the edge gateway that do not have an address binding are allocated an IP address from this pool. IP pool ranges cannot intersect one another, thus one IP address can belong to only one IP pool.

Note:

At least one DHCP IP pool must be configured to have the DHCP service status turned on.

Prerequisites

To use the vCloud Director tenant portal to work with edge gateway services, the edge gateway must be converted to an advanced edge gateway. You can do this on the edge gateway in the vCloud Director Web console or from the tenant portal. For details on performing this step from the tenant portal, see Convert an Edge Gateway to an Advanced Edge Gateway.

Procedure

  1. Open Edge Gateway Services.
    1. Navigate to Networking > Edges.
    2. Select the edge gateway to edit, and click Configure Services.
  2. Navigate to DHCP > Pools .
  3. If DHCP service is not currently enabled, turn on the DHCP Service Status toggle.
    Note:

    Add at least one DHCP IP pool before saving changes after turning on the DHCP Service Status toggle. If no DHCP IP pools are listed on the screen and you turn on the DHCP Service Status toggle and save the changes, the screen displays with the toggle turned off.

  4. Under DHCP Pools, click the Create (Add button) button, specify the details for the DHCP pool, and click Keep.

    Option

    Description

    IP Range

    Type in a range of IP addresses.

    Domain Name

    Domain name of the DNS server.

    Auto Configure DNS

    Turn on this toggle to use the DNS service configuration for this IP pool DNS binding.

    If enabled, the Primary Name Server and Secondary Name Server are set to Auto.

    Primary Name Server

    When you do not enable Auto Configure DNS, type your primary DNS server IP address of your primary DNS server.

    This IP address is used for hostname-to-IP address resolution.

    Secondary Name Server

    When you do not enable Auto Configure DNS, type your secondary DNS server IP address.

    This IP address is used for hostname-to-IP address resolution.

    Default Gateway

    Type the default gateway address.

    When you do not specify the default gateway IP address, the internal interface of the edge gateway instance is taken as the default gateway.

    Subnet Mask

    Type the subnet mask of the edge gateway interface.

    Lease Never Expires

    Enable this toggle to keep the IP addresses that are assigned out of this pool bound to their assigned virtual machines forever.

    When you select this option, Lease Time is set to infinite.

    Lease Time (Seconds)

    Length of time (in seconds) that the DHCP-assigned IP addresses are leased to the clients.

    The default lease time is one day (86400 seconds).

    Note:

    You cannot specify a lease time when you select Lease never expires.

  5. Click Save changes.

Results

vCloud Director updates the edge gateway to provide DHCP services.
