5.2.12.1 Platform Event Filtering (PEF)
The mBMC monitors platform health and logs failure events into the SEL. The Platform Event
Filtering feature provides a configurable mechanism to allow events to trigger alert actions. PEF
provides a flexible, general mechanism that enables the mBMC to perform selectable actions
triggered by a configurable set of platform events. The mBMC supports the following IPMI PEF
actions:
• Power-down
• Soft shut-down
• Power cycle
• Reset
• Diagnostic Interrupt
• Alert
The mBMC maintains an Event Filter table with 30 entries that is used to select the actions to
perform. Also maintained is a fixed/read-only Alert Policy Table entry. No alert strings are
supported.
Note: All Fault/Status LED and ID LED behaviors are driven off of PEF. PEF should not be
disabled and the as shipped entry configuration should not be modified or those behaviors will
be changed.
Each time the PEF module receives either an externally or internally generated event message,
it compares the event data against the entries in the event filter table. The mBMC scans all
entries in the table and determines a set of actions to be performed. If a combination of actions
is identified, such as power down, power cycle, and/or reset actions, the action are performed
according to PEF Action Priorities. Action priorities are outlined in the table below.
Note: An action that has changed from delayed to non-delayed, or an action whose delay time
has been reduced has a higher priority. Each generated event is logged by SEL.
