Cisco NBAR Protocol Discovery MIB NBAR - Network Based Application Recognition is an intelligent classification engine that recognizes applications that are static (which use fixed TCP or UDP port numbers), and stateful (which dynamically assign TCP or UDP port numbers). Protocol Discovery - uses NBAR to show you the mix of applications currently running on the network. Key statistics are associated with each protocol. These statistics can be used to define traffic classes and QoS policies. Functionality: 1. To enable/disable Protocol Discovery per interface. 2. Display the protocols/applications which NBAR currently recognizes. 3. To display various Protocol Discovery statistics. 4. A configurable top N table which lists protocols using user defined criteria. 5. To configure notifications (traps) based on configurable statistic thresholds. 6. To maintain a history table of all notification events.

Added comment that cnpdStatusLastUpdateTime becomes
zero when PD disabled.
Added comment that during overflow in cnpdAllStatsTable,
the 32 bit counter not valid. There is no overflow
support for it. One should only use the HC (64 bit)
counters to get the stats in cnpdAllStatsTable
Default cnpdTopNConfigStatsSelect changed from
'bitRateSum' to 'byteCountSum'.
Added better rowStatus descriptions to TopNConfig and
ThresholdConfig tables.
Added comment to explain what TopNSampleTime really does -
i.e only changes sample time for bitrate on an interface.
Changed sizes of TopN and Threshold tables according to
memory requirements and recommendations from various
platforms.
Added following objects to cnpdThresholdHistoryTable:
cnpdThresholdHistoryValue
cnpdThresholdHistoryType
cnpdThresholdHistoryProtocol
cnpdThresholdHistoryStatsSelect
Changed reported objects in Notification Table to reflect
changes in cnpdThresholdHistoryTable.
