Adding DHCP Clients to a DHCP Server

A DHCP client is a network device using DHCP service to obtain network cofiguration parameters such as an IP address from a DHCP server. When a DHCP client sends a broadcast message to locate a DHCP server, the DHCP server provides configuration parameters (IP address, MAC address, domain name, and a lease for the IP address) to the client.

The following table describes the two types of DHCP clients employed in Network & Virtual Switch.

DHCP Client


Physical Adapter DHCP Client

Enabling a DHCP IPv4 address allows the device to automatically acquire an IPv4 address for a specific physical adapter from a DHCP server. The physical adapter is assigned an IP address by the DHCP server for a predefined lease time.


For details on obtaining a DHCP provided IP address, see Configuring IPv4 Settings.

Virtual Switch DHCP Client

Virtual switches allow virtual machines to obtain IP-related configurations automatically from an external DHCP server. The virtual switch obtains the IP address from the DHCP server through the connected physical adapter on the device.

  1. A virtual switch configured with an automatic DHCP IP address cannot utilize the NAT and DHCP server functions.

  2. Virtual switches cannot automatically acquire the IP address of the physical adapter unless the virtual switch has been configured to connect to a physical adapter in Network > Virtual Switch.

  1. Go to Control Panel > Network & File Services > Network & Virtual Switch.

    The Network & Virtual Switch window opens.

  2. Go to Network > DHCP Server.
  3. Identify a DHCP server.
  4. Under Actions, click .

    The DHCP Client Table window appears.

  5. Click Add Reserved IP.

    The Add Reserved IP window appears.

  6. Configure the DHCP client information.


    User Action

    Device Name

    Specify a device name for the DHCP client.

    IP Address

    Specify the IP address of the DHCP client.

    MAC Address

    Specify the MAC address of the DHCP client.

  7. Click Apply.

Network & Virtual Switch adds the DHCP client.
