Concept Guide

On the DHCP server, the format for option 60 is “ InstantAP“, and the two formats for option 43 are
“<organization>,<ams-ip>,<ams-key>” and “<organization>,<ams-domain>” .
If you use the <organization>,<ams-ip>,<ams-key> format, the PSK-based authentication is used to access
the W-AirWave Management Platform server.
If you use the <organization>,<ams-domain> format, the W-IAP resolves the domain name into two IP
address as W-AirWave Primary W-AirWave Backup, and then W-IAP starts a certificate-based authentication
with W-AirWave Management platform server, instead of the PSK login.
For option 43, when you choose to enter the domain name, the IP address and key are not available.
Enabling DNS-based Discovery of the Provisioning AMP server
W-IAPs can now automatically discover the provisioning AMP server if the DHCP option 43 and Activate cannot
perform zero-touch provisioning and transfer W-AirWave configuration to the W-IAP.
When a domain option xxx is included in the DHCP configuration, the W-IAP will search the DNS server records
for aruba-airwave.xxx. When there is no domain option, the W-IAP will only the server records for aruba-
airwave.
To enable W-IAPs to automatically discover the AMP server, create a DNS record for aruba-airwave.xxx or
aruba-airwave in the DNS server. To use this feature on the W-AirWave side, enable certificate based login.
For information on how to enable certificate based login, see PSK-based and Certificate-based Authentication
on page 298.
Standard DHCP option 60 and 43 on Windows Server 2008
In networks that are not using DHCP option 60 and 43, it is easy to use the standard DHCP options 60 and 43
for an AP or W-IAP. For APs, these options can be used to indicate the master controller or the local controller.
For W-IAPs, these options can be used to define the W-AirWave IP, group, password, and domain name.
1. From a server running Windows Server 2008 navigate to Server Manager > Roles > DHCP
sever>domain DHCP Server > IPv4.
2. Right-click IPv4 and select Set Predefined Options.
