Question:  Why should I avoid using a certain range of IP addresses for the controller when RAPs are deployed?

 

Product and Software: This article applies to all Aruba controllers and ArubaOS versions.

By default, ArubaOS has a predefined DHCP scope in the default ap-system-profile. The DHCP scope is defined as 192.168.11.0/24.


As a result, you should avoid using this range elsewhere.


For instance if the IP address of the controller is 192.168.11.1, undesirable results may occur when the home user tries to zero provision. The RAP believes that this address is local, so though the initial IPsec exchange is completed, the configuration download does not complete. The problem occurs because the RAP attempts to talk to the IP address of the controller.


A change request has been opened to address this limitation and a fix will be available soon.
In the meantime, to avoid this limitation, use a different address for the IP address of the controller and preprovision the RAP locally before you deploy it.
