To ensure that wireless clients can continue to be authenticated on the network and can access resources and applications, eliminate single points of failure in your network infrastructure by including:

  • Redundant services (such as Active Directory domain controllers) on separate subnets.

  • Clustered DHCP services, in the event that one of the cluster nodes fails.

  • DNS on all domain controllers, in the event that a DNS server fails.

  • Redundant RADIUS servers and proxies, to provide fault tolerance for RADIUS-based authentication.

  • Redundant switches and routers, in the event that a switch or router fails.

  • Redundant network paths between switches and routers.
