Setting the Switch Information in the DHCP Option
Instead of statically configuring the wireless switch IP address in the AP, you can configure
the DHCP server on your network to pass the IP addresses of up to four D-Link WLAN
Controller Switches to the access point in DHCP option 43. If you configured a static IP
address in the D-Link Access Point, the AP ignores DHCP option 43.
The procedures to add the DHCP option to the DHCP server depend on the type of DHCP
server you use on your network. If you use a Microsoft Windows 2000 or Microsoft Windows
2003 DHCP Server, you configure the scope you use with the access points with DHCP
Option 43, as the following procedures describe.
1. From the DHCP manager, right-click the applicable scope and select Configure
Options...
2. From the Available Options list, scroll to Option 43 and select the 043 Vendor Specific
Info check box.
3. Enter the Option 43 data into the Data Entry field.
The format for DHCP option 43 values are defined by RFC 2132. To enter an IP address
of 192.168.1.10 into the Binary column, you enter the data type code (01) and the address
length (04), followed by the IP address in hexadecimal format. You repeat the data type
and address length codes for each address you enter.
For example, to add the four switch IP addresses 192.168.1.10, 192.168.2.10,
192.168.3.10, and 192.168.4.16 to Option 43, you enter the following hexadecimal
numbers into the Data Entry field:
01 04 0C A8 01 0A 01 04 0C A8 02 0A 01 04 0C A8 03 0A 01 04 0C A8 04 10
