Parameter Description
Transmit MFP Frames When enabled, the access point protects the management frames it transmits by adding a
message integrity check information element (MIC IE) to each frame. Any attempt to copy,
alter, or replay the frame invalidates the MIC, causing any receiving access point configured to
detect MFP frames to report the discrepancy. An access point must be a member of a WDS to
transmit MFP frames. If it is not, a warning message appears on this page.
Detect MFP Frames When MFP detection is enabled, the access point validates every management frame that it
receives from other access points in the network. It ensures that the MIC IE is present (when
the originator is configured to transmit MFP frames) and matches the content of the
management frame.
If it receives any frame that does not contain a valid MIC IE from a BSSID belonging to an
access point that is configured to transmit MFP frames, it reports the discrepancy to the
network management system (WLSE). The access point must be a member of a WDS to
detect MFP frames. If it is not, a warning message appears on this page.
Distribute Keys At least one WDS in the network must be configured to distribute signature keys to the MFP
generators (protectors) and MFP detectors (validators) in the network. These are required by
the generators to create MIC IEs and by the detectors to validate MIC IEs.
A device that is configured to distribute keys creates error reports also from data received
from the detecting access points and forwards them to the WLSE.This check box is not
present if the access point cannot be a WDS.
