Configuring Link Latency
The controller shows this metric regardless of direction:
• Link test request/reply round-trip time (minimum, maximum, and average)
The controller software supports CCX versions 1 through 5. CCX support is enabled automatically for every
WLAN on the controller and cannot be disabled. The controller stores the CCX version of the client in its
client database and uses it to limit the features for this client. If a client does not support CCXv4 or v5, the
controller performs a ping link test on the client. If a client supports CCXv4 or v5, the controller performs a
CCX link test on the client. If a client times out during a CCX link test, the controller switches to the ping
link test automatically.
