• Mac clients are OS-Specific.
• Too new a client wont work with too old an
  operating system and vice-versa
• Particularly change from 10.0 to 10.1 to 10.2
• Support for Linux 2.6 Kernels only from version
  4.0.4B.
• Tighter Cisco licensing restrictions.
• Updates are regular watch the CISCO website.
