Voice VNS DHCP Page - Fields and Buttons

Field/Button Description
DHCP Option From the drop-down list, click one of the following:
  • Use DHCP Relay — Using DHCP (Dynamic Host Configuration Protocol) relay forces the controller to forward DHCP requests to an external DHCP server on the enterprise network. DHCP relay bypasses the local DHCP server for the controller and allows the enterprise to manage IP address allocation to a VNS from its existing infrastructure.

  • DHCP Servers — Type the IP address of the DHCP server to which DHCP discover and request messages will be forwarded for clients on this VNS. The controller does not handle DHCP requests from users, but instead forwards the requests to the indicated DHCP server.

    The DHCP server must be configured to match the VNS settings. In particular for a Routed VNS, the DHCP server must identify the controller's interface IP as the default Gateway (router) for the subnet. (Users intending to reach devices outside of the subnet will forward the packets to the default gateway (controller) for delivery upstream.)

  • Local DHCP Server — If applicable, edit the local DHCP server settings.

DNS Servers Type the IP Address of the Domain Name Servers to be used.
WINS Type the IP address if the DHCP server uses Windows Internet Naming Service (WINS).
