Provides instructions for configuring, disabling, and monitoring 802.11w, including step-by-step procedures for GUI-based and other configurations to ensure effective implementation and management of 802.11w features.
Configure 802.11w (GUI)
To protect management traffic against spoofing and replay attacks, configure 802.11w settings after enabling WPA and AKM.
Before you begin
Ensure WPA and AKM are configured on the target WLAN.Procedure
| 1. | Choose . |
|
| 2. | Click Add to create WLANs. The Add WLAN page is displayed. |
|
| 3. | In the tab, navigate to the Protected Management Frame section. |
|
| 4. | Choose PMF as Disabled, Optional, or Required. By default, the PMF is disabled. If you choose PMF as Optional or Required, you can view these fields:
|
|
| 5. | Click Save & Apply to Device. |
802.11w PMF is enabled with the parameters you selected. This strengthens the security of management frames on the WLAN.
Configure 802.11w (CLI)
Before you begin
-
Configure WPA.
-
Configure AKM (Authentication and Key Management) on the WLAN.
Procedure
| 1. | Enter global configuration mode. Example:
|
|
| 2. | Configure a WLAN and enters configuration mode. Example:
|
|
| 3. | Configure 802.1x support using the security wpa akm dot1x-sha256 command. Example:
|
|
| 4. | Configure the 802.11w association comeback time. Example:
Example:
|
|
| 5. | Require clients to negotiate 802.11w PMF protection on a WLAN. Example:
|
|
| 6. | Configure time interval identified in milliseconds before which the SA query response is expected. Example:
Example:
If the device does not get a response, another SQ query is tried. |
802.11w Protected Management Frames are enabled and mandatory on the specified WLAN, providing improved protection of management frames.
Disable 802.11w
Procedure
| 1. | Enter global configuration mode. Example:
|
|
| 2. | Configure a WLAN and enters configuration mode. Example:
|
|
| 3. | Disable 802.1x support using the no security wpa akm dot1x-sha256 command. Example:
|
|
| 4. | Configure the 802.11w association comeback time. Example:
|
|
| 5. | Disable client negotiation of 802.11w PMF protection on a WLAN. Example:
|
|
| 6. | Disable SQ query retry. Example:
|
802.11w PMF protection is disabled for the specified WLAN.
Monitor 802.11w
Use these commands to monitor 802.11w.
Procedure
| 1. | Display the WLAN parameters on the WLAN. The PMF parameters are displayed.
|
|
| 2. | Display the summary of the 802.11w authentication key management configuration on a client.
