Alternate Method for Defining Vendor-Specific DHCP Options
This section describes how to add vendor-specific DHCP options for Aruba Instant APs in a network that already uses DHCP options 60 and 43 for other services. Some networks use DHCP standard options 60 and 43 to give the DHCP clients info about certain services such as PXE to the DHCP clients. In such an environment, it is not possible to use the standard DHCP options 60 and 43 for Aruba APs.
This method describes how to set up a DHCP server to send option 43 with AirWave information to Aruba Instant IAP. This section assumes that option 43 is sent per scope because option 60 is being shared by other devices as well.

This scope should be specific to Instant, and the PXE devices that use options 60 and 43 should not connect to the subnet defined by this scope. This is because you can specify only one option 43 for a scope, and if other devices that use option 43 connect to this subnet, they are presented with Instant-specific information. |
| 1. | In server 2008, navigate to Server Manager > Roles > DHCP Server > Domain DHCP Server |
| 2. | Select a scope (subnet). Scope (10.169.145.0)145 is selected in the example shown in the figure below. |
| 3. | Right click and select and then specify the following options: |
| | Vendor class— DHCP Standard Options |
| | User class— Default User Class |
| | Available options— Select 043 Vendor-Specific Info |
| | String Value— ArubaInstantAP, tme-store4, 10.169.240.8, Aruba123 (which is the AP description, organization string, AirWave IP address, Pre-shared key for AirWave) |

Upon completion, the IAP shows up as a new device in AirWave, and a new group called tme-store4 is created. Navigate to to view this group.
