I know that the tftp is used for the fimrware upgrade
But the ftp port for what is used? We need ti put an ap in a plce which has restrict access in porta. They are not allowed to use ftp port, neither tftp port. All the otherports that the cobtroller use is allowed so there js no issue. But for what the cobtroler use the ftp port between controller and ap?? Do i rrally need it?
