  • 1.  Aruba RAP IP Pool Increase

    Posted Mar 27, 2026 07:16 AM

    Hi All,

    We're getting uncomfortably close to the default RAP IP address pool limits.  What's the best way to increase this limit as there's no netmask for a conventional subnet? 

    IP addresses used in pool home-rap-pool
             1.1.3.25-1.1.3.247
     
    IPv4 pool : Total - 223 IPs used - 3 IPs free - 226 IPs configured

    Should I simply change the range to 1.1.3.25-1.1.4.254? And what would be the implication for the current RAPs that're terminated and active? 
    Thanks in advance.

    I have not tried to extend and existing pool, but you can add a new pool without impacting inner-IP assignments from the current pool. so when the first pool is exhausted, RAPs will start using the second pool.

    Thanks, ariyap. Your suggestion sounds like a great solution and honestly a much better way to approach the issue. I really appreciate you taking the time to share it-I'll give it a try during our next change window.

    Please be aware that the 1.1.3.x IP range is public assigned. You may see unpredictable connectivity issues.

    Although the RAP pool is only used between the AP and controller, it means that AP and controller can't externally communicate with those IP addresses. It's better to use non-routable IP space, like 169.254.0.0/16 or 100.64.0.0/10; or allocate a block in your internal IP addressing plan. When changing, it may be a good moment to reconsider the IP address space.

    Thanks, Herman. Thanks for pointing that out - I had assumed that value was a system default, but clearly that's not the case. Really appreciate you flagging it. We'll take a look at updating these IPs on our side in due course.
