Configuring the DHCP Option
You can configure the IP address of the DWS-4000 Series switch as an option in the DHCP response to the DHCP
request that the AP sends the DHCP server.
The AP can learn up to four switch IP addresses or DNS names through DHCP option 43 (the Vendor
Information option) in the DHCP response. If you configured a static IP address in the AP, the AP ignores DHCP
option 43.
The format for DHCP option 43 values are defined by RFC 2132.
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...
Note: This discovery method only works if you configure the DHCP option before the AP receives its
network information from the DHCP server.
