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"

-- textual conventions
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."

STATUS current
DESCRIPTION
"This object identifies the source of the data that
this etherStats entry is configured to analyze. This
source can be any ethernet interface on this device.
In order to identify a particular interface, this object
shall identify the instance of the ifIndex object,
defined in RFC 2233 [17], for the desired interface.
For example, if an entry were to receive data from
interface #1, this object would be set to ifIndex.1.
The statistics in this group reflect all packets
on the local network segment attached to the identified
interface.
An agent may or may not be able to tell if fundamental
changes to the media of the interface have occurred and
necessitate an invalidation of this entry. For example, a
hot-pluggable ethernet card could be pulled out and replaced
by a token-ring card. In such a case, if the agent has such
knowledge of the change, it is recommended that it
invalidate this entry.

This object can be used as a reasonable estimate of
10-Megabit ethernet utilization. If greater precision is
desired, the etherStatsPkts and etherStatsOctets objects
should be sampled before and after a common interval. The
differences in the sampled values are Pkts and Octets,
respectively, and the number of seconds in the interval is
Interval. These values are used to calculate the Utilization
as follows:
Pkts * (9.6 + 6.4) + (Octets * .8)
Utilization = -------------------------------------
Interval * 10,000
The result of this equation is the value Utilization which
is the percent utilization of the ethernet segment on a

Note that this definition of jabber is different
than the definition in IEEE-802.3 section 8.2.1.5
(10BASE5) and section 10.3.1.4 (10BASE2). These
documents define jabber as the condition where any
packet exceeds 20 ms. The allowed range to detect
jabber is between 20 ms and 150 ms."
::= { etherStatsEntry 12 }
etherStatsCollisions OBJECT-TYPE
SYNTAX Counter32
UNITS "Collisions"
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The best estimate of the total number of collisions
on this Ethernet segment.
The value returned will depend on the location of the
RMON probe. Section 8.2.1.3 (10BASE-5) and section
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."

-- Once samples are taken, their data is stored in an entry

--
-- If the probe keeps track of the time of day, it should start

minimum time in which any counter could overflow on a
particular media type and set the historyControlInterval
object to a value less than this interval. This is

UNITS "Collisions"

DESCRIPTION
"The best estimate of the total number of collisions
on this Ethernet segment during this sampling

The value returned will depend on the location of the
RMON probe. Section 8.2.1.3 (10BASE-5) and section
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."

-- The Alarm Group
-- Implementation of the Alarm group is optional. The Alarm Group
-- requires the implementation of the Event group.
-- Consult the MODULE-COMPLIANCE macro for the authoritative
-- conformance information for this MIB.
--
-- The Alarm group periodically takes statistical samples from
-- variables in the probe and compares them to thresholds that have
-- been configured. The alarm table stores configuration
-- entries that each define a variable, polling period, and
-- threshold parameters. If a sample is found to cross the
-- threshold values, an event is generated. Only variables that
-- resolve to an ASN.1 primitive type of INTEGER (INTEGER, Integer32,
-- Counter32, Counter64, Gauge32, or TimeTicks) may be monitored in
-- this way.
--
-- This function has a hysteresis mechanism to limit the generation
-- of events. This mechanism generates one event as a threshold
-- is crossed in the appropriate direction. No more events are
-- generated for that threshold until the opposite threshold is
-- crossed.
--
-- In the case of a sampling a deltaValue, a probe may implement
-- this mechanism with more precision if it takes a delta sample
-- twice per period, each time comparing the sum of the latest two
-- samples to the threshold. This allows the detection of threshold
-- crossings that span the sampling boundary. Note that this does
-- not require any special configuration of the threshold value.
-- It is suggested that probes implement this more precise algorithm.

acceptable means of restricting the read access that
could be obtained through the alarm mechanism, the
probe must only grant write access to this object in
those views that have read access to all objects on
the probe.
During a set operation, if the supplied variable name is
not available in the selected MIB view, a badValue error
must be returned. If at any time the variable name of

-- The Host Group
-- Implementation of the Host group is optional.
-- Consult the MODULE-COMPLIANCE macro for the authoritative
-- conformance information for this MIB.
--
-- The host group discovers new hosts on the network by
-- keeping a list of source and destination MAC Addresses seen
-- in good packets. For each of these addresses, the host group
-- keeps a set of statistics. The hostControlTable controls
-- which interfaces this function is performed on, and contains
-- some information about the process. On behalf of each
-- hostControlEntry, data is collected on an interface and placed
-- in both the hostTable and the hostTimeTable. If the
-- 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.

-- The Host Top "N" Group
-- Implementation of the Host Top N group is optional. The Host Top N
-- group requires the implementation of the host group.
-- Consult the MODULE-COMPLIANCE macro for the authoritative
-- conformance information for this MIB.
--
-- The Host Top N group is used to prepare reports that describe
-- the hosts that top a list ordered by one of their statistics.
-- The available statistics are samples of one of their
-- base statistics, over an interval specified by the management
-- station. Thus, these statistics are rate based. The management
-- station also selects how many such hosts are reported.
-- The hostTopNControlTable is used to initiate the generation of
-- such a report. The management station may select the parameters
-- of such a report, such as which interface, which statistic,
-- how many hosts, and the start and stop times of the sampling.
-- When the report is prepared, entries are created in the
-- hostTopNTable associated with the relevant hostTopNControlEntry.
-- These entries are static for each report after it has been
-- prepared.
