CHAPTER 6: COMMAND LINE INTERFACE

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.
