pmf

Function

The pmf command enables the Protected Management Frame (PMF) function of a VAP.

The undo pmf command disables the PMF function for a VAP.

By default, the PMF function is disabled for a VAP.

Usage Guidelines

Usage Scenario

PMF is a specification released by Wi-Fi Alliance (WFA) based on IEEE 802.11w standards. It aims to apply security measures defined in WPA2 to unicast and multicast management action frames to improve network credibility.

If management frames transmitted on WLANs are not encrypted, the following security problems may be introduced. PMF can address the problems.

Hackers intercept management frames exchanged between the APs and users.
Hackers pretend to be APs and send Disassociation and Deauthentication frames to disconnect users.
Hackers pretend to be users and send Disassociation frames to APs to disconnect the users.

Precautions

The authentication and encryption mode must be WPA2–AES in the security profile.

Modifying configuration in the security profile will disconnect all users on the VAP that uses the security profile. The users need to reassociate with the VAP to go online.

The PMF function cannot be deployed on Mesh networks.

Example

# Enable the PMF function in optional mode.
