Field/Button Description
DHCP Option From the drop-down list, click one of the following:
Use DHCP Relay — Using DHCP relay forces the SCALANCE
IWLAN Controller to forward DHCP requests to an external DHCP
server on the enterprise network. DHCP relay bypasses the local
DHCP server for the SCALANCE IWLAN 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 SCALANCE IWLAN 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 SCALANCE IWLAN 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).
