Dear Leo Laohoo

thanks for the reply .as you know i have WLC 5508 with 25 APs Supported my requirement is 40 APs

now wich part op licences i needed.

LIC-CT5508-50A

Dear Dear Leo Laohoo

25.0        AIR-CT5508-25-K9            Cisco 5508 Series Wireless Controller for up to 25 APs

25.0.1    CON-SCN-CT0825             SC CORE 8X5XNBD Cisco 5508 Series

25.1        SWC5500K9-74  Cisco Unified Wireless Controller SW Release 7.4

25.2        AIR-PWR-CORD-CE          AIR Line Cord Central Europe

25.3        LIC-CT5508-25    25 AP Base license

25.4        LIC-CT5508-BASE              Base Software License

25.5        PI-MSE-PRMO-INSRT     Insert Packout - PI-MSE

This what we have, which part number we required to have 25 APs more license on this wireless Controller.

Why you mentioned me 50APs licenses , what I believe if I have 25 APs licenses existing as mentioned above in BOQ and if I will buy 25 APs license more than it will fulfil my requirement then why I need to go with LIC-CT5508-50A.

Please Clarify to me.

Why you mentioned me 50APs licenses

Because the licensing system of the 5508/WiSM2 are from a "distorted reality".  The appliance already has 25 license.  This means you CANNOT purchase adder license of 25 license AND BELOW.  You're only allowed to purchase adder licenses ABOVE  and only once.  This means you can only buy 1 50 AP license before you hit the "mother load" and purchase 100 AP license.

thanks a lot  Leo Laohoo.
