As login failures accumulate from a specific IP address, they are "aged" by an internal counter.
When the login failures reach the maximum age of the internal counter window, they are deleted
(or forgiven). When a valid login occurs from an IP address that is not penalized (the excessive
login failures are being held in cfgRacTuneIpBlkPenaltyTime), all previous login failures for the IP
address are deleted. The failure history cannot be cleared except by a valid login attempt.
When the excessive failures are detected, login will be blocked for a pre-selected time span.
However, this feature can be disabled to allow login from the targeted IP address.
Dell strongly recommends using the IP blocking feature and setting the limit on invalid login
attempts to your environment requirements.
