Configuring the DHCP Option

You can configure the IP address of the Unified 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.
This discovery method only works if you configure the DHCP option before the AP receives its network
information from the DHCP server.
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.
