You must send options back to the AP. We had to send DHCP Client Options:
15 - domain name xxxx.xxxx.xxx
3 - gateway of the network you are configuring
43 - in HEX letters, the IP address of your aruba controller. Like ac:11:ff:a6 for 172.17.255.166
60 - in STRING format, the name ArubaAP spelled just like that
You can configure the first 3 by going into your network definition. Click on the Deployment Options tab, goto New and add options 15, 3, and 43. Option 43 muse be HEX separated by colons - like ac:11:ff:a6 for 172.17.255.166
To define option 60 and have it appear in the drop down menu the same as options 15, 3, and 43, you must follow these instructions: ( NOTE: this is configured in a more global, higher level than your network definition. A tab named 'DHCP Settings' will appear and that is how you begin to configure this option 60 STRING value of ArubaAP to be sent back to the AP.)
Adding DHCP Custom Options - option 60 ArubaAP
Use DHCP custom options when you have software or applications that require a nonstandard DHCP option.
A small number of custom options including option 150 (TFTP server), 176 (IP Telephones), and 252 (WPAD) are available in the Address Manager user interface as DHCP client options. Options that are not included can be added as DHCP custom options.
DHCP custom options are created from a configuration’s DHCP Settings tab. After creating a custom option, it is available as a DHCP client option.
To add a DHCP custom option:
Select the My IPAM tab. From the configuration drop-down menu, select a configuration.
Select the IP Space tab. Tabs remember the page you last worked on, so select the IP Space tab again to ensure you are working with the Configuration information page.
Click the DHCP Settings tab.
Under DHCP Custom Option Definition, click New. The Add DHCP Custom Deployment Option page opens.
Under General, define the custom option:
Option Code—select the DHCP option code number.
Name—type a descriptive name for the custom option.
Type—select a type from the drop-down list:
