-

mandatory

Indicates the mandatory mode, in which the VAP permits access only from PMF-capable STAs.

Usage Guidelines

Application 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.

The PMF function is supported only by the AP2051DN, AP2051DN-S, AP2051DN-E, AP5050DN-S, AP2X30DN, AP3030DN, AP3010DN-V2, AP4030DN, AP2050DN, AP2050DN-S, AP2050DN-E, AP8130DN-W, AP4130DN, AP4030DN-E, AP5030DN, AP5030DN-S, AP5130DN, AP8030DN, AP8130DN, AP9131DN, AP9132DN, AD9430DN-24 (including the mapping RUs), AD9430DN-12 (including the mapping RUs), AD9431DN-24X (including the mapping RUs), AP4030TN, AP6050DN, AP6150DN, AP4050DN-E, AP4050DN-HD, AP7050DN-E, AP7050DE, AP4050DN, AP4051DN, AP4151DN, AP4050DN-S, AP4051DN-S, AP8050DN, AP8150DN, AP8050DN-S, AP1050DN-S, AP4051TN, AP6052DN, AP7052DN, AP7152DN, AP7052DE, AP8050TN-HD, AP8082DN, AP8182DN.
