Usage Guidelines

Usage Scenario

To ensure secure encryption during WPA or WPA2 authentication, enable periodic PTK update. You can run this command to configure the PTK update interval. A smaller interval indicates faster PTK update and more secure data encryption. However, if the PTK update interval is set too small, the STA and AP implement more negotiations, affecting the throughput.


The configured periodic PTK update interval takes effect only after you enable the periodic PTK update function using the wpa ptk-update enable command.


# Set the periodic PTK update interval to 50,000 seconds.
