Thanks Cappalli,
I conveyed the same to the customer, but than he ask to provide any document from Aruba which shows that XM only support 32 CAP's. I tried to find on website but there is data sheet showing capabilities of 3200 series controller not 3200XM controller. I shall be thankful to you if you can provide me the such document.
My customer was saying 3200XM can support 128 RAPs or 128 CAP'. But as per my understanding 3200XM can support either 32 CAPS or 128 RAP's
