Usage Guidelines

Usage Scenario

In WPA or WPA2 authentication and encryption, a Pairwise Transient Key (PTK) is generated at the key negotiation stage to encrypt unicast radio packets. To ensure secure encryption, enable periodic PTK update so that the AP and STA use a new PTK to encrypt radio packets after a regular interval.

Precautions

When periodic PTK update is implemented, some STAs may encounter service interruptions or go offline due to individual problems.

Follow-up Procedure

Run the wpa ptk-update ptk-update-interval command to configure the periodic PTK update interval.

Example

# Enable the periodic PTK update function.

<HUAWEI> system-view
