+ DESCRIPTION
+ "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 "200005110000Z" -- 11 May, 2000
+ DESCRIPTION
+ "Reformatted into SMIv2 format.
+
+ This version published as RFC 2819."
+
+ REVISION "199502010000Z" -- 1 Feb, 1995
+ DESCRIPTION
+ "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"

+OwnerString ::= TEXTUAL-CONVENTION
+ STATUS current
+ DESCRIPTION
+ "This data type is used to model an administratively
+ assigned name of the owner of a resource. Implementations
+ must accept values composed of well-formed NVT ASCII
+ sequences. In addition, implementations should accept
+ values composed of well-formed UTF-8 sequences.
+
+ It is suggested that this name contain one or more of
+ the following: IP address, management station name,
+ network manager's name, location, or phone number.
+ In some cases the agent itself will be the owner of
+ an entry. In these cases, this string shall be set
+ to a string starting with 'monitor'.
+
+ SNMP access control is articulated entirely in terms
+ of the contents of MIB views; access to a particular
+ SNMP object instance depends only upon its presence
+ or absence in a particular MIB view and never upon
+ its value or the value of related object instances.
+ Thus, objects of this type afford resolution of
+ resource contention only among cooperating
+ managers; they realize no access control function
+ with respect to uncooperative parties."
+ SYNTAX OCTET STRING (SIZE (0..127))
+
+EntryStatus ::= TEXTUAL-CONVENTION
+ STATUS current
+ DESCRIPTION
+ "The status of a table entry.
+
+ Setting this object to the value invalid(4) has the
+ effect of invalidating the corresponding entry.
+ That is, it effectively disassociates the mapping
+ identified with said entry.
+ It is an implementation-specific matter as to whether
+ the agent removes an invalidated entry from the table.
+ Accordingly, management stations must be prepared to
+ receive tabular information from agents that corresponds
+ to entries currently not in use. Proper
+ interpretation of such entries requires examination
+ of the relevant EntryStatus object.
+
+ An existing instance of this object cannot be set to
+ createRequest(2). This object may only be set to
+ createRequest(2) when this instance is created. When
+ this object is created, the agent may wish to create
+ supplemental object instances with default values
+ to complete a conceptual row in this table. Because the
+
+ creation of these default objects is entirely at the option
+ of the agent, the manager must not assume that any will be
+ created, but may make use of any that are created.
+ Immediately after completing the create operation, the agent
+ must set this object to underCreation(3).
+
+ When in the underCreation(3) state, an entry is allowed to
+ exist in a possibly incomplete, possibly inconsistent state,
+ usually to allow it to be modified in multiple PDUs. When in
+ this state, an entry is not fully active.
+ Entries shall exist in the underCreation(3) state until
+ the management station is finished configuring the entry
+ and sets this object to valid(1) or aborts, setting this
+ object to invalid(4). If the agent determines that an
+ entry has been in the underCreation(3) state for an
+ abnormally long time, it may decide that the management
+ station has crashed. If the agent makes this decision,
+ it may set this object to invalid(4) to reclaim the
+ entry. A prudent agent will understand that the
+ management station may need to wait for human input
+ and will allow for that possibility in its
+ determination of this abnormally long period.
+
+ An entry in the valid(1) state is fully configured and
+ consistent and fully represents the configuration or
+ operation such a row is intended to represent. For
+ example, it could be a statistical function that is
+ configured and active, or a filter that is available
+ in the list of filters processed by the packet capture
+ process.
+
+ A manager is restricted to changing the state of an entry in
+ the following ways:
+
+ To: valid createRequest underCreation invalid
+ From:
+ valid OK NO OK OK
+ createRequest N/A N/A N/A N/A
+ underCreation OK NO OK OK
+ invalid NO NO NO OK
+ nonExistent NO OK NO OK
+
+ In the table above, it is not applicable to move the state
+ from the createRequest state to any other state because the
+ manager will never find the variable in that state. The
+ nonExistent state is not a value of the enumeration, rather
+ it means that the entryStatus variable does not exist at all.
+
+ An agent may allow an entryStatus variable to change state in
+ additional ways, so long as the semantics of the states are
+ followed. This allowance is made to ease the implementation of
+ the agent and is made despite the fact that managers should
+ never exercise these additional state transitions."

+ DESCRIPTION
+ "The best estimate of the total number of collisions

+ 10.3.1.3 (10BASE-2) of IEEE standard 802.3 states that a
+ station must detect a collision, in the receive mode, if
+ three or more stations are transmitting simultaneously. A
+ repeater port must detect a collision when two or more
+
+ stations are transmitting simultaneously. Thus a probe
+ placed on a repeater port could record more collisions
+ than a probe connected to a station on the same segment
+ would.
+
+ Probe location plays a much smaller role when considering
+ 10BASE-T. 14.2.1.4 (10BASE-T) of IEEE standard 802.3
+ defines a collision as the simultaneous presence of signals
+ on the DO and RD circuits (transmitting and receiving
+ at the same time). A 10BASE-T station can only detect
+ collisions when it is transmitting. Thus probes placed on
+ a station and a repeater, should report the same number of
+ collisions.
+
+ Note also that an RMON probe inside a repeater should
+ ideally report collisions between the repeater and one or
+ more other hosts (transmit collisions as defined by IEEE
+ 802.3k) plus receiver collisions observed on any coax
+ segments to which the repeater is connected."

+-- monitoring device finds itself short of resources, it may
+-- delete entries as needed. It is suggested that the device
+-- delete the least recently used entries first.
+
+-- The hostTable contains entries for each address discovered on
+-- a particular interface. Each entry contains statistical
+-- data about that host. This table is indexed by the
+-- MAC address of the host, through which a random access
+-- may be achieved.
+
+-- The hostTimeTable contains data in the same format as the
+-- hostTable, and must contain the same set of hosts, but is
+-- indexed using hostTimeCreationOrder rather than hostAddress.
+-- The hostTimeCreationOrder is an integer which reflects
+-- the relative order in which a particular entry was discovered
+-- and thus inserted into the table. As this order, and thus
+-- the index, is among those entries currently in the table,
+-- the index for a particular entry may change if an
+-- (earlier) entry is deleted. Thus the association between
+-- hostTimeCreationOrder and hostTimeEntry may be broken at
+-- any time.
+
+-- The hostTimeTable has two important uses. The first is the
+-- fast download of this potentially large table. Because the
+-- index of this table runs from 1 to the size of the table,
+-- inclusive, its values are predictable. This allows very
+-- efficient packing of variables into SNMP PDU's and allows
+-- a table transfer to have multiple packets outstanding.
+-- These benefits increase transfer rates tremendously.
+
+-- The second use of the hostTimeTable is the efficient discovery
+-- by the management station of new entries added to the table.
+-- After the management station has downloaded the entire table,
+-- it knows that new entries will be added immediately after the
+-- end of the current table. It can thus detect new entries there
+-- and retrieve them easily.
+
+-- Because the association between hostTimeCreationOrder and
+-- hostTimeEntry may be broken at any time, the management
+-- station must monitor the related hostControlLastDeleteTime
+-- object. When the management station thus detects a deletion,
+-- it must assume that any such associations have been broken,
+-- and invalidate any it has stored locally. This includes
+
+-- restarting any download of the hostTimeTable that may have been
+-- in progress, as well as rediscovering the end of the
+-- hostTimeTable so that it may detect new entries. If the
+-- management station does not detect the broken association,
+-- it may continue to refer to a particular host by its
+-- creationOrder while unwittingly retrieving the data associated
+-- with another host entirely. If this happens while downloading
+-- the host table, the management station may fail to download
+-- all of the entries in the table.

+-- Each event entry is fired by an associated condition located

+-- Each eventEntry may optionally specify that a log entry
+-- be created on its behalf whenever the event occurs.
+-- Each entry may also specify that notification should
