protected-mgmt-frames

Configures the WLAN's frame protection mode and SA (security association) query parameters

802.11w provides protection for both unicast management frames and broadcast/multicast management frames. The ‘robust management frames‘ are action, disassociation, and de-authentication frames. The standard provides one security protocol CCMP for protection of unicast robust management frames. The PMF (Protected management frames) protocol only applies to robust management frames after establishment of RSNA PTK (Robust Security Network association Pairwise Transient Key). Robust management frame protection is achieved by using CCMP for unicast management frames, broadcast/multicast integrity protocol for broadcast/multicast management frames and SA query protocol for protection against (re)association attacks.

Supported on the following devices:

Syntax

protected-mgmt-frames [mandatory|optional|sa-query [attempts <1-10>|timeout <100-1000>]

Parameters

protected-mgmt-frames [mandatory|optional|sa-query [attempts <1-10>|timeout <100-1000>]
protected-mgmt-frames Enables and configures WLAN's frame protection mode and SA query parameters. Use this command to specify whether management frames are continually or optionally protected. Frame protection mode is disabled by default.
mandatory Enforces PMF on this WLAN (management frames are continually optionally protected)
optional Provides PMF only for those clients that support PMF (management frames are optionally protected)
sa-query [attempts <1-10>| timeout <100-1000>] Configures the following SA parameters:
  • attempts <1-10> – Configures the number of SA query attempts from 1 - 10. The default is 5.
  • timeout <100-1000> – Configures the interval, in milliseconds, used to timeout association requests that exceed the defined interval. Specify a value from 100 - 1000 milliseconds. The default value is 201 milliseconds.
