known to be already authenticated, so it proceeds directly to key exchange

and association.

• To support pre-authentication, both clients and access points in the network

must be WPA2 enabled.

• Pre-authentication requires all access points in the network to be on the

same IP subnet.

Example

Link Integrity Commands

The access point provides a link integrity feature that can be used to ensure that

wireless clients are connected to resources on the wired network. The access point

does this by periodically sending Ping messages to a host device in the wired

Ethernet network. If the access point detects that the connection to the host has

failed, it disables the radio interfaces, forcing clients to find and associate with

another access point. When the connection to the host is restored, the access point

re-enables the radio interfaces.
