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.
