ip pool

Dear all, I have a few problem. i use ip pool and it's works fine if i define ip pool in mysql. 779084,"test","password","=","test123" 779085,"test","Pool-Name",":=","main_pool1" 779086,"test","Called-Station-Id","=","hostpot1" The problem happened if i have 2 access point in the same area and IP the different is only at called-station-id. what should i set in radius if any user can go to AP 1 with Called-Station-Id 1 or AP 2 with Called-Station-Id 2. if user logged in AP1 they will get main_pool1 and if user logged in AP2 they will get main_pool2 sorry for my bad language:)
