The Packet Forwarding Engine technology are Cisco developed Network Processors, which accelerates certain features in order to provide better network performance.
An agent uses this MIB to monitor the performance history on any active PFE pipeline listed in the ENTITY-MIB (RFC 2737) entPhysicalTable. This monitoring is via measurement periods of actual, 1-minute, 5-minutes and 15-minutes.
For the 1-minute and 5-minute measurement periods, perfor- mance statistics are calculated and displayed based on pre- vious 1 minute and 5 minute respectively.
For the 15-minute period, the performance statistics are accumulated in fifteen minute intervals. At any one time, an agent maintains one current (incomplete) interval and up to 96 completed intervals (24 hours worth). Fewer than 96 intervals of data will be available if the agent has been restarted within the last 24 hours. In addition, there is a rolling 24-hour total of each performance statistic.
There is no requirement for an agent to ensure fixed rela- tionship between the start of a fifteen minute interval and any wall clock; however some agents may align the fifteen minute intervals with quarter hours.
EventType1 = none2 = log3 = notify4 = logAndNotifyType of action to execute when an event occurs.
'none' Neither log an entry in the cePfeHistTable, nor
sent out an SNMP notification.
'log' Create a cePfeHistTable entry, but do not sent out
an SNMP notification.
'notify' Sent out an SNMP notification, but do not create a
log entry in the cePfeHistTable.
'logAndNotify' Both create a log entry in the cePfeHistTable and sent out an SNMP notification. · Integer32
This object indicates what type of action should be taken by the agent when a event is generated.
cePfeHistTableSize
1.3.6.1.4.1.9.9.265.1.2.2
Unsigned32 (0..500)
This object specifies the number of entries that the cePfeHistTable can contain. When a event is generated, and the capacity of the cePfeHistTable has reached the value specified by this object, then the agent deletes the oldest entity in order to accommodate the new entry. A value of '0' prevents any history from being retained.
cePfeHistTableLastIndex
1.3.6.1.4.1.9.9.265.1.2.3
Unsigned32
This object specifies the value of the cePfeHistIndex object corresponding to the last entry added to the table by the agent. It will return zero if there are no entries in the table.
If the management client uses the notifications defined by this module, then it can poll this object to determine whether it has missed a notification sent by the agent.

To summarize RFC 854, the NVT ASCII repertoire specifies:
- the use of character codes 0-127 (decimal)
- the graphics characters (32-126) are interpreted as US ASCII
- NUL, LF, CR, BEL, BS, HT, VT and FF have the special meanings specified in RFC 854
- the other 25 codes have no standard interpretation
- the sequence 'CR LF' means newline
- the sequence 'CR NUL' means carriage-return
- an 'LF' not preceded by a 'CR' means moving to the same column on the next line.
- the sequence 'CR x' for any x other than LF or NUL is illegal. (Note that this also means that a string may end with either 'CR LF' or 'CR NUL', but not with CR.)

TimeStampThe value of the sysUpTime object at which a specific occurrence happened. The specific occurrence must be
defined in the description of any object defined using this type.
If sysUpTime is reset to zero as a result of a re- initialization of the network management (sub)system, then the values of all TimeStamp objects are also reset. However, after approximately 497 days without a re- initialization, the sysUpTime object will reach 2^^32-1 and then increment around to zero; in this case, existing values of TimeStamp objects do not change. This can lead to ambiguities in the value of TimeStamp objects. · TimeTicks
This object specifies the value of the sysUpTime object at the time the event was generated.
