/*							-- DO NOT EDIT --
 * Generated by smidump version 0.4.3:
 *   smidump -f scli \
 *     --scli-include='historyControlEntry' RMON-MIB
 *
 * Derived from RMON-MIB:
 *   Remote network monitoring devices, often called
 *   monitors or probes, are instruments that exist for
 *   the purpose of managing a network. This MIB defines
 *   objects for managing remote network monitoring devices.
 *
 * Revision 2000-05-11 00:00:
 *   Reformatted into SMIv2 format.
 *   
 *   This version published as RFC 2819.
 *
 * Revision 1995-02-01 00:00:
 *   Bug fixes, clarifications and minor changes based on
 *   implementation experience, published as RFC1757 [18].
 *   
 *   Two changes were made to object definitions:
 *   
 *   1) A new status bit has been defined for the
 *   captureBufferPacketStatus object, indicating that the
 *   packet order within the capture buffer may not be identical to
 *   the packet order as received off the wire.  This bit may only
 *   be used for packets transmitted by the probe.  Older NMS
 *   applications can safely ignore this status bit, which might be
 *   used by newer agents.
 *   
 *   2) The packetMatch trap has been removed.  This trap was never
 *   actually 'approved' and was not added to this document along
 *   with the risingAlarm and fallingAlarm traps. The packetMatch
 *   trap could not be throttled, which could cause disruption of
 *   normal network traffic under some circumstances. An NMS should
 *   configure a risingAlarm threshold on the appropriate
 *   channelMatches instance if a trap is desired for a packetMatch
 *   event. Note that logging of packetMatch events is still
 *   supported--only trap generation for such events has been
 *   removed.
 *   
 *   In addition, several clarifications to individual object
 *   definitions have been added to assist agent and NMS
 *   implementors:
 *   
 *   - global definition of 'good packets' and 'bad packets'
 *   
 *   - more detailed text governing conceptual row creation and
 *     modification
 *   
 *   - instructions for probes relating to interface changes and
 *     disruptions
 *   
 *   - clarification of some ethernet counter definitions
 *   
 *   - recommended formula for calculating network utilization
 *   
 *   - clarification of channel and captureBuffer behavior for some
 *     unusual conditions
 *   
 *   - examples of proper instance naming for each table
 *
 * Revision 1991-11-01 00:00:
 *   The original version of this MIB, published as RFC1271.
