-- File: RFC1757.MIB - CCD-RMON-MIB
-- Changes:
-- Changed IMPORT of DisplayString to RFC1213-MIB
-- from RFC1158-MIB.
-- Added import for TimeTicks from RFC1155-SMI.
-- dperkins@scruznet.com

mib-2 FROM RFC1213-MIB

-- 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 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 mutiple 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:
--
-- create under
-- To: valid Request Creation 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
-- excercise these additional state transitions.

SYNTAX OBJECT IDENTIFIER
ACCESS read-write
STATUS mandatory
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 1213 and RFC 1573 [4,6], 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.

DESCRIPTION
"The total number of octets of data (including
those in bad packets) received on the

FCS octets).
This object can be used as a reasonable estimate of
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

Check Sequence (FCS) with an integral number of
octets (FCS Error) or a bad FCS with a non-integral

Frame Check Sequence (FCS) with an integral number
of octets (FCS Error) or a bad FCS with a
non-integral number of octets (Alignment Error).
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."
::= { rEtherStatsEntry 12 }
rEtherStatsCollisions OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
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."

-- The History Control Group
-- Implementation of the History Control group is optional.
--
-- The history control group controls the periodic statistical
-- sampling of data from various types of networks. The
-- historyControlTable 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. Each counter in the
-- etherHistoryEntry counts the same event as its
-- similarly-named counterpart in the etherStatsEntry,
-- except that each value here is a cumulative sum during a
-- sampling period.
--
-- 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 probe 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.

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

"The interval in seconds over which the data is
sampled for each bucket in the part of the
media-specific table associated with this
historyControlEntry. 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.

it counts both runts (which are normal occurrences
due to collisions) and noise hits."

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

rEtherHistoryCollisions OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The best estimate of the total number of collisions
on this Ethernet segment during this sampling
interval.
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.
--
-- 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.

DESCRIPTION
"The interval in seconds over which the data is

should be taken in the case of deltaValue
sampling - the interval should be set short enough
that the sampled variable is very unlikely to

SYNTAX OBJECT IDENTIFIER
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 to
invalid(4).
This object may not be modified if the associated
