RFC1271-MIB DEFINITIONS ::= BEGIN
IMPORTS
Counter FROM RFC1155-SMI
mib-2, DisplayString FROM RFC1213-MIB
OBJECT-TYPE FROM RFC-1212;
-- This MIB module uses the extended OBJECT-TYPE macro as
-- defined in [9].
-- Remote Network Monitoring MIB
rmon OBJECT IDENTIFIER ::= { mib-2 16 }
-- textual conventions
OwnerString ::= DisplayString
-- This data type is used to model an administratively
-- assigned name of the owner of a resource. This
-- information is taken from the NVT ASCII character set.
-- 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.
--
-- By convention, objects with this syntax are declared
-- as having
--
-- SIZE (0..127)
EntryStatus ::= INTEGER
{ valid(1),
createRequest(2),
underCreation(3),
invalid(4)
}
-- 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 to complete a conceptual
-- row in this table. Immediately after completing the
-- create operation, the agent must set this object to
-- underCreation(3).
--
-- 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.

-- The Statistics Group
--
-- Implementation of the Statistics group is optional.
--
-- The statistics group contains statistics measured by the

-- statistics take the form of free running counters that
-- start from zero when a valid entry is created.
--
-- This group currently has statistics defined only for
-- Ethernet interfaces. Each etherStatsEntry contains
-- statistics for one Ethernet interface. The probe must
-- create one etherStats entry for each monitored Ethernet
-- interface on the device.

-- The History Group
-- Implementation of the History group is optional.
--
-- The history group records periodic statistical samples from
-- a network and stores them for later retrieval. The
-- historyControl table stores configuration entries that each
-- define an interface, polling period, and other parameters.
-- Once samples are taken, their data is stored in an entry
-- in a media-specific table. Each such entry defines one
-- sample, and is associated with the historyControlEntry that
-- caused the sample to be taken. Currently the only media-
-- specific table defined is the etherHistoryTable, for
-- Ethernet networks.
--
-- If the probe keeps track of the time of day, it should
-- start the first sample of the history at a time such that
-- when the next hour of the day begins, a sample is
-- started at that instant. This tends to make more
-- user-friendly reports, and enables comparison of reports
-- from different probes that have relatively accurate time
-- of day.
--
-- The monitor is encouraged to add two history control entries
-- per monitored interface upon initialization that describe
-- a short term and a long term polling period. Suggested
-- parameters are 30 seconds for the short term polling
-- period and 30 minutes for the long term period.

SYNTAX INTEGER (1..65535)

DESCRIPTION
"The number of discrete sampling intervals
over which data shall be saved in the part of
the media-specific table associated with this
historyControl entry.
When the associated historyControlBucketsRequested
object is created or modified, the probe
should set this object as closely to the requested
value as is possible for the particular
probe implementation and available resources. The
probe must not lower this value except as a result
of a modification to the associated
historyControlBucketsRequested object.
There will be times when the actual number of
buckets associated with this entry is less than
the value of this object. In this case, at the
end of each sampling interval, a new bucket will
be added to the media-specific table.
When the number of buckets reaches the value of
this object and a new bucket is to be added to the
media-specific table, the oldest bucket associated
with this historyControlEntry shall be deleted by
the agent so that the new bucket can be added.
When the value of this object changes to a value less
than the current value, entries are deleted
from the media-specific table associated with this
historyControlEntry. Enough of the oldest of these
entries shall be deleted by the agent so that their
number remains less than or equal to the new value of
this object.
When the value of this object changes to a value
greater than the current value, the number of
associated media-specific entries may be allowed
to grow."

historyControlInterval OBJECT-TYPE
SYNTAX INTEGER (1..3600)
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The interval in seconds over which the data is
sampled for each bucket in the part of the
media-specific table associated with this
historyControl entry. This interval can
be set to any number of seconds between 1 and
3600 (1 hour).
Because the counters in a bucket may overflow at their
maximum value with no indication, a prudent manager
will take into account the possibility of overflow
in any of the associated counters. It is important
to consider the 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 typically most
important for the 'octets' counter in any
media-specific table. For example, on an Ethernet
network, the etherHistoryOctets counter could overflow
in about one hour at the Ethernet's maximum
utilization.
This object may not be modified if the associated
historyControlStatus object is equal to valid(1)."

-- The Alarm Group
-- Implementation of the Alarm group is optional.
--
-- The Alarm Group requires the implementation of the Event
-- group.
--
-- 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, Counter,
-- Gauge, 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.

ACCESS read-write
STATUS mandatory
DESCRIPTION
"The object identifier of the particular variable to
be sampled. Only variables that resolve to an ASN.1
primitive type of INTEGER (INTEGER, Counter, Gauge,
or TimeTicks) may be sampled.
Because SNMP access control is articulated entirely
in terms of the contents of MIB views, no access
control mechanism exists that can restrict the value of
this object to identify only those objects that exist
in a particular MIB view. Because there is thus no
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 an established alarmEntry is
no longer available in the selected MIB view, the
probe must change the status of this alarmEntry

-- The Host Group
-- Implementation of the Host group is optional.
--
-- 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 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 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.

DESCRIPTION
"The status that is to be matched with the input

The following two rules are then applied to every
packet:
(1) For each relevant bit from the packet status
with the corresponding filterPktStatusNotMask
bit set to zero, if the bit from the packet
status is not equal to the corresponding bit
from the filterPktStatus, then the packet will
fail this status match.
(2) If for every relevant bit from the packet status
with the corresponding filterPktStatusNotMask
bit set to one, the bit from the packet status
is equal to the corresponding bit from the
filterPktStatus, then the packet will fail
this status match.
Any packets that have not failed either of the two
matches above have passed this status match.
The value of the packet status is a sum. This sum
initially takes the value zero. Then, for each
error, E, that has been discovered in this packet,
2 raised to a value representing E is added to the sum.
The errors and the bits that represent them are
dependent on the media type of the interface that
this channel is receiving packets from.
The errors defined for a packet captured off of an
Ethernet interface are as follows:
bit # Error
0 Packet is longer than 1518 octets
1 Packet is shorter than 64 octets
2 Packet experienced a CRC or Alignment
error
For example, an Ethernet fragment would have a
value of 6 (2^1 + 2^2).
As this MIB is expanded to new media types, this
object will have other media-specific errors defined.
For the purposes of this status matching algorithm, if
the packet status is longer than this

extended with '0' bits until it reaches the size of
the packet status.

this packet is associated."
::= { captureBufferEntry 1 }
captureBufferIndex OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"An index that uniquely identifies an entry
in the captureBuffer table associated with a
particular bufferControlEntry. This index will
start at 1 and increase by one for each new packet
added with the same captureBufferControlIndex."
::= { captureBufferEntry 2 }
captureBufferPacketID OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"An index that describes the order of packets
that are received on a particular interface.
The packetID of a packet captured on an
interface is defined to be greater than the
packetID's of all packets captured previously on
the same interface. As the captureBufferPacketID
object has a maximum positive value of 2^31 - 1,
any captureBufferPacketID object shall have the
value of the associated packet's packetID mod 2^31."
::= { captureBufferEntry 3 }
captureBufferPacketData OBJECT-TYPE
SYNTAX OCTET STRING
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The data inside the packet, starting at the beginning
of the packet plus any offset specified in the
associated bufferControlDownloadOffset, including any
link level headers. The length of the data in this
object is the minimum of the length of the captured
packet minus the offset, the length of the associated
bufferControlCaptureSliceSize minus the offset, and the
associated bufferControlDownloadSliceSize. If this
minimum is less than zero, this object shall have a
length of zero."

DESCRIPTION
"The number of milliseconds that had passed since
this capture buffer was first turned on when this
packet was captured."
::= { captureBufferEntry 6 }
captureBufferPacketStatus OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"A value which indicates the error status of this
packet.
The value of this object is defined in the same way as
filterPacketStatus. The value is a sum. This sum
initially takes the value zero. Then, for each
error, E, that has been discovered in this packet,
2 raised to a value representing E is added to the sum.
The errors defined for a packet captured off of an
Ethernet interface are as follows:
bit # Error
0 Packet is longer than 1518 octets
1 Packet is shorter than 64 octets
2 Packet experienced a CRC or Alignment
error
3 First packet in this capture buffer after
it was detected that some packets were
not processed correctly.
For example, an Ethernet fragment would have a
value of 6 (2^1 + 2^2).
As this MIB is expanded to new media types, this object
will have other media-specific errors defined."

-- The Event Group
-- Implementation of the Event group is optional.
--
-- The Event group controls the generation and notification
-- of events from this device. Each entry in the eventTable
-- describes the parameters of the event that can be triggered.
-- Each event entry is fired by an associated condition located
-- elsewhere in the MIB. An event entry may also be associated
-- with a function elsewhere in the MIB that will be executed
-- when the event is generated. For example, a channel may
-- be turned on or off by the firing of an event.
--
-- 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
-- occur by way of SNMP trap messages. In this case, the
-- community for the trap message is given in the associated
-- eventCommunity object. The enterprise and specific trap
-- fields of the trap are determined by the condition that
-- triggered the event. Three traps are defined in a companion
-- document: risingAlarm, fallingAlarm, and packetMatch.
-- If the eventTable is triggered by a condition specified
-- elsewhere, the enterprise and specific trap fields
-- must be specified for traps generated for that condition.
