1. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the
current Internet-Standard Management Framework, please
refer to section 7 of RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information
store, termed the Management Information Base or MIB. MIB
objects are generally accessed through the Simple Network
Management Protocol (SNMP). Objects in the MIB are defined
using the mechanisms defined in the Structure of Management
Information (SMI). This memo specifies a MIB module that
is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58,
RFC 2580 [RFC2580].

Internet Draft Remote Network Monitoring MIB Oct 3, 2005
2. Overview
The RMON2 MIB defines objects that provide RMON analysis up to
the application layer.
Remote network monitoring devices, often called monitors or
probes, are instruments that exist for the purpose of managing
a network. Often these remote probes are stand-alone devices
and devote significant internal resources for the sole purpose
of managing a network. An organization may employ many of
these devices, one per network segment, to manage its
internet. In addition, these devices may be used for a
network management service provider to access a client
network, often geographically remote.
The objects defined in this document are intended as an
interface between an RMON agent and an RMON management
application and are not intended for direct manipulation by
humans. While some users may tolerate the direct display of
some of these objects, few will tolerate the complexity of
manually manipulating objects to accomplish row creation.
These functions should be handled by the management
application.
2.1. Remote Network Management Goals
o Offline Operation
There are sometimes conditions when a management
station will not be in constant contact with its
remote monitoring devices. This is sometimes by
design in an attempt to lower communications costs
(especially when communicating over a WAN or
dialup link), or by accident as network failures
affect the communications between the management
station and the probe.
For this reason, this MIB allows a probe to be
configured to perform diagnostics and to collect
statistics continuously, even when communication with
the management station may not be possible or
efficient. The probe may then attempt to notify
the management station when an exceptional condition
occurs. Thus, even in circumstances where
Steven Waldbusser Expires April 3, 2006 [Page 5]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
communication between management station and probe is
not continuous, fault, performance, and configuration
information may be continuously accumulated and
communicated to the management station conveniently
and efficiently.
o Proactive Monitoring
Given the resources available on the monitor, it
is potentially helpful for it continuously to run
diagnostics and to log network performance. The
monitor is always available at the onset of any
failure. It can notify the management station of the
failure and can store historical statistical
information about the failure. This historical
information can be played back by the management
station in an attempt to perform further diagnosis
into the cause of the problem.
o Problem Detection and Reporting
The monitor can be configured to recognize
conditions, most notably error conditions, and
continuously to check for them. When one of these
conditions occurs, the event may be logged, and
management stations may be notified in a number of
ways.
o Value Added Data
Because a remote monitoring device represents a
network resource dedicated exclusively to network
management functions, and because it is located
directly on the monitored portion of the network, the
remote network monitoring device has the opportunity
to add significant value to the data it collects.
For instance, by highlighting those hosts on the
network that generate the most traffic or errors, the
probe can give the management station precisely the
information it needs to solve a class of problems.
o Multiple Managers
An organization may have multiple management stations
for different units of the organization, for different
functions (e.g. engineering and operations), and in an
attempt to provide disaster recovery. Because
environments with multiple management stations are
Steven Waldbusser Expires April 3, 2006 [Page 6]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
common, the remote network monitoring device has to
deal with more than own management station,
potentially using its resources concurrently.
2.2. Structure of MIB
The objects are arranged into the following groups:
- protocol directory
- protocol distribution
- address mapping
- network layer host
- network layer matrix
- application layer host
- application layer matrix
- user history
- probe configuration
These groups are the basic units of conformance. If a remote
monitoring device implements a group, then it must implement
all objects in that group. For example, a managed agent that
implements the network layer matrix group must implement the
nlMatrixSDTable and the nlMatrixDSTable.
Implementations of this MIB must also implement the IF-MIB
[RFC2863].
These groups are defined to provide a means of assigning
object identifiers, and to provide a method for managed agents
to know which objects they must implement.
This document also contains enhancements to tables defined in
the RMON MIB [RFC2819]. These enhancements include:
1) Adding the DroppedFrames and LastCreateTime
Steven Waldbusser Expires April 3, 2006 [Page 7]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
conventions to each table defined in the RMON MIB.
2) Augmenting the RMON filter table with a mechanism
that allows filtering based on an offset from the
beginning of a particular protocol, even if the
protocol headers are variable length.
3) Augmenting the RMON filter and capture status bits
with additional bits for WAN media and generic media.
These bits are defined here as:
Bit Definition
6 For WAN media, this bit is set for packets
coming from one direction and cleared for
packets coming from the other direction.
It is an implementation specific matter
as to which bit is assigned to which
direction, but it must be consistent for
all packets received by the agent, and if
the agent knows which end of the link is
"local" and which end is "network", the bit
should be set for packets from the "local"
side and should be cleared for packets from
the "network" side.
7 For any media, this bit is set for any packet
with a physical layer error. This bit may be
set in addition to other media-specific bits
that denote the same condition.
8 For any media, this bit is set for any packet
that is too short for the media. This bit may
be set in addition to other media-specific
bits that denote the same condition.
9 For any media, this bit is set for any packet
that is too long for the media. This bit may
be set in addition to other media-specific bits
that denote the same condition.
These enhancements are implemented by RMON-2 probes that also
implement RMON and do not add any requirements to probes that
are compliant to just RMON.

Internet Draft Remote Network Monitoring MIB Oct 3, 2005
3. Control of Remote Network Monitoring Devices
Due to the complex nature of the available functions in these
devices, the functions often need user configuration. In many
cases, the function requires parameters to be set up for a
data collection operation. The operation can proceed only
after these parameters are fully set up.
Many functional groups in this MIB have one or more tables in
which to set up control parameters, and one or more data
tables in which to place the results of the operation. The
control tables are typically read/write in nature, while the
data tables are typically read/only. Because the parameters
in the control table often describe resulting data in the data
table, many of the parameters can be modified only when the
control entry is not active. Thus, the method for modifying
these parameters is to de-activate the entry, perform the SNMP
Set operations to modify the entry, and then re-activate the
entry. Deleting the control entry causes the deletion of any
associated data entries, which also gives a convenient method
for reclaiming the resources used by the associated data.
Some objects in this MIB provide a mechanism to execute an
action on the remote monitoring device. These objects may
execute an action as a result of a change in the state of the
object. For those objects in this MIB, a request to set an
object to the same value as it currently holds would thus
cause no action to occur.
To facilitate control by multiple managers, resources have to
be shared among the managers. These resources are typically
the memory and computation resources that a function requires.
3.1. Resource Sharing Among Multiple Management Stations
When multiple management stations wish to use functions that
compete for a finite amount of resources on a device, a method
to facilitate this sharing of resources is required.
Potential conflicts include:
o Two management stations wish to simultaneously use
resources that together would exceed the capability of
the device.
Steven Waldbusser Expires April 3, 2006 [Page 9]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
o A management station uses a significant amount of
resources for a long period of time.
o A management station uses resources and then crashes,
forgetting to free the resources so others may
use them.
The OwnerString mechanism is provided for each management
station initiated function in this MIB to avoid these
conflicts and to help resolve them when they occur. Each
function has a label identifying the initiator (owner) of the
function. This label is set by the initiator to provide for
the following possibilities:
o A management station may recognize resources it owns
and no longer needs.
o A network operator can find the management station that
owns the resource and negotiate for it to be freed.
o A network operator may decide to unilaterally free
resources another network operator has reserved.
o Upon initialization, a management station may recognize
resources it had reserved in the past. With this
information it may free the resources if it no longer
needs them.
Management stations and probes should support any format of
the owner string dictated by the local policy of the
organization. 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. This
information will help users to share the resources more
effectively.
There is often default functionality that the device or the
administrator of the probe (often the network administrator)
wishes to set up. The resources associated with this
functionality are then owned by the device itself or by the
network administrator, and are intended to be long-lived. In
this case, the device or the administrator will set the
relevant owner object to a string starting with 'monitor'.
Indiscriminate modification of the monitor-owned configuration
by network management stations is discouraged. In fact, a
network management station should only modify these objects
under the direction of the administrator of the probe.
Steven Waldbusser Expires April 3, 2006 [Page 10]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
Resources on a probe are scarce and are typically allocated
when control rows are created by an application. Since many
applications may be using a probe simultaneously,
indiscriminate allocation of resources to particular
applications is very likely to cause resource shortages in the
probe.
When a network management station wishes to utilize a function
in a monitor, it is encouraged to first scan the control table
of that function to find an instance with similar parameters
to share. This is especially true for those instances owned
by the monitor, which can be assumed to change infrequently.
If a management station decides to share an instance owned by
another management station, it should understand that the
management station that owns the instance may indiscriminately
modify or delete it.
It should be noted that a management application should have
the most trust in a monitor-owned row because it should be
changed very infrequently. A row owned by the management
application is less long-lived because a network administrator
is more likely to re-assign resources from a row that is in
use by one user than from a monitor-owned row that is
potentially in use by many users. A row owned by another
application would be even less long-lived because the other
application may delete or modify that row completely at its
discretion.
3.2. Row Addition Among Multiple Management Stations
The addition of new rows is achieved using the RowStatus
Textual Convention [RFC2579]. In this MIB, rows are often
added to a table in order to configure a function. This
configuration usually involves parameters that control the
operation of the function. The agent must check these
parameters to make sure they are appropriate given
restrictions defined in this MIB as well as any implementation
specific restrictions such as lack of resources. The agent
implementor may be confused as to when to check these
parameters and when to signal to the management station that
the parameters are invalid. There are two opportunities:
o When the management station sets each parameter object.
Steven Waldbusser Expires April 3, 2006 [Page 11]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
o When the management station sets the row status object
to active.
If the latter is chosen, it would be unclear to the management
station which of the several parameters was invalid and caused
the badValue error to be emitted. Thus, wherever possible,
the implementor should choose the former as it will provide
more information to the management station.
A problem can arise when multiple management stations attempt
to set configuration information simultaneously using SNMP.
When this involves the addition of a new conceptual row in the
same control table, the managers may collide, attempting to
create the same entry. To guard against these collisions,
each such control entry contains a status object with special
semantics that help to arbitrate among the managers. If an
attempt is made with the row addition mechanism to create such
a status object and that object already exists, an error is
returned. When more than one manager simultaneously attempts
to create the same conceptual row, only the first will
succeed. The others will receive an error.
In the RMON MIB [RFC2819], the EntryStatus textual convention
was introduced to provide this mutual exclusion function.
Since then, this function was added to the SNMP framework as
the RowStatus textual convention. The RowStatus textual
convention is used for the definition of all new tables.
When a manager wishes to create a new control entry, it needs
to choose an index for that row. It may choose this index in
a variety of ways, hopefully minimizing the chances that the
index is in use by another manager. If the index is in use,
the mechanism mentioned previously will guard against
collisions. Examples of schemes to choose index values
include random selection or scanning the control table looking
for the first unused index. Because index values may be any
valid value in the range and they are chosen by the manager,
the agent must allow a row to be created with any unused index
value if it has the resources to create a new row.
Some tables in this MIB reference other tables within this
MIB. When creating or deleting entries in these tables, it is
generally allowable for dangling references to exist. There
is no defined order for creating or deleting entries in these
Steven Waldbusser Expires April 3, 2006 [Page 12]

tables.
Steven Waldbusser Expires April 3, 2006 [Page 13]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
4. Conventions
The following conventions are used throughout the RMON MIB and
its companion documents.
Good Packets
Good packets are error-free packets that have a valid frame
length. For example, on Ethernet, good packets are error-free
packets that are between 64 octets long and 1518 octets long.
They follow the form defined in IEEE 802.3 section 3.2.all.
Bad Packets
Bad packets are packets that have proper framing and are
therefore recognized as packets, but contain errors within the
packet or have an invalid length. For example, on Ethernet,
bad packets have a valid preamble and SFD, but have a bad CRC,
or are either shorter than 64 octets or longer than 1518
octets.
Steven Waldbusser Expires April 3, 2006 [Page 14]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
5. RMON 2 Conventions
The following practices and conventions are introduced in the
RMON 2 MIB.
5.1. Usage of the term Application Level
There are many cases in this MIB where the term Application
Level is used to describe a class of protocols or a
capability. This does not typically mean a protocol that is
an OSI Layer 7 protocol. Rather, it is used to identify a
class of protocols that is not limited to MAC-layer and
network-layer protocols, but can also include transport,
session, presentation, and application-layer protocols.
5.2. Protocol Directory and Limited Extensibility
Every RMON 2 implementation will have the capability to parse
certain types of packets and identify their protocol type at
multiple levels. The protocol directory presents an inventory
of those protocol types the probe is capable of monitoring,
and allows the addition, deletion, and configuration of
protocol types in this list.
One concept deserves special attention: the "limited
extensibility" of the protocol directory table. The RMON 2
model is that protocols are detected by static software that
has been written at implementation time. Therefore, as a
matter of configuration, an implementation does not have the
ability to suddenly learn how to parse new packet types.
However, an implementation may be written such that the
software knows where the demultiplexing field is for a
particular protocol, and can be written in such a way that the
decoding of the next layer up is table-driven. This works
when the code has been written to accomodate it and can be
extended no more than one level higher. This extensibility is
called "limited extensibility" to highlight these limitations.
However, this can be a very useful tool.
For example, suppose that an implementation has C code that
understands how to decode IP packets on any of several
ethernet encapsulations, and also knows how to interpret the
Steven Waldbusser Expires April 3, 2006 [Page 15]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
IP protocol field to recognize UDP packets and how to decode
the UDP port number fields. That implementation may be table-
driven so that among the many different UDP port numbers
possible, it is configured to recognize 161 as SNMP, port 53
as DNS, and port 69 as TFTP. The limited extensibility of the
protocol directory table would allow an SNMP operation to
create an entry that would create an additional table mapping
for UDP that would recognize UDP port 123 as NTP and begin
counting such packets.
This limited extensibility is an option that an implementation
can choose to allow or disallow for any protocol that has
child protocols.
5.3. Errors in packets
Packets with link-level errors are not counted anywhere in
this MIB because most variables in this MIB requires the
decoding of the contents of the packet, which is meaningless
if there is a link-level error.
Packets in which protocol errors are detected are counted for
all protocols below the layer in which the error was
encountered. The implication of this is that packets in which
errors are detected at the network-layer are not counted
anywhere in this MIB, while packets with errors detected at
the transport layer may have network-layer statistics counted.

new enumerations support the creation of high capacity topN
reports in the High Capacity RMON MIB [RFC3273].
Additionally, the following objects have been deprecated as
they have not had enough independent implementations to

type.
Further, the SerialConfigEntry SEQUENCE definition included
sub-typing information that is not allowed in SMIv2. This
information has been deleted. Ranges were added to a number of
objects and textual-conventions to constrain their maximum
(and sometimes minimum) sizes. The addition of these ranges
documents existing practice for these objects. These objects
are:

performed by an application that is not aware of the special
TimeFilter semantics."

-- Textual Conventions
ZeroBasedCounter32 ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"This TC describes an object which counts events with the
following semantics: objects of this type will be set to
zero(0) on creation and will thereafter count appropriate
events, wrapping back to zero(0) when the value 2^32 is
reached.
Provided that an application discovers the new object within
the minimum time to wrap it can use the initial value as a
delta since it last polled the table of which this object is
part. It is important for a management station to be aware of
this minimum time and the actual time between polls, and to
discard data if the actual time is too long or there is no
defined minimum time.
Typically this TC is used in tables where the INDEX space is
constantly changing and/or the TimeFilter mechanism is in use."
SYNTAX Gauge32
LastCreateTime ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"This TC describes an object that stores the value of the
sysUpTime object at the last time its entry was created.
This can be used for polling applications to determine that an
entry has been deleted and re-created between polls, causing
an otherwise undetectable discontinuity in the data.
If sysUpTime is reset to zero as a result of a re-
initialization of the network management (sub)system, then
the values of all LastCreateTime objects are also reset.
However, after approximately 497 days without a re-
initialization, the sysUpTime object will reach 2^^32-1 and
then increment around to zero; in this case, existing values
of TimeStamp objects do not change. This can lead to
ambiguities in the value of TimeStamp objects."

An entry is considered changed if the value of any object in the
entry changes, if the row is created, or if any object in the
entry is created or deleted. Note that deleted entries cannot
be detected or downloaded.
A time-filtered conceptual table is created by inserting a
single object of SYNTAX TimeFilter as the first INDEX component
in a copy of an existing basic conceptual table (i.e., any
SEQUENCE without a TimeFilter INDEX component). Thus, for
each conceptual entry 'I' in the basic table, there exists N
conceptual entries in the time-filtered version, (indexed N.I)
where 'N' is equal to the value of sysUpTime.
When an application retrieves conceptual instances from a
time-filtered table, and an INDEX value is provided for the
TimeFilter INDEX component 'N', the agent will only consider
returning basic conceptual entries (e.g., 'fooColumn.N.I') if
any column within the basic conceptual entry has changed since
sysUpTime equals 'N'. If not, the basic conceptual entry will
be ignored for the particular retrieval operation.
When sysUpTime is equal to zero, this table shall be empty.
One conceptual entry exists for each past value of sysUpTime,
except that the whole table is purged should sysUpTime wrap.
As an entry in a time-filtered table is updated (i.e., one of
the columns in the basic conceptual table is changed), new
conceptual entries are also created in the time-filtered version
(which still share the now updated object values with all other
instances). The number of unique time-filtered instances which
are created is determined by the value of sysUpTime at which the
basic entry was last updated. One unique instance will exist
for each value of sysUpTime at the last update time for the row.
However, a new TimeFilter index instance is created for each new
sysUpTime value. The TimeFilter index values not associated
Steven Waldbusser Expires April 3, 2006 [Page 22]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
with entry updates are called duplicate time-filtered instances.
After some deployment experience, it has been determined that
a time-filtered table is more efficient to use if the agent
stops a 'MIB walk' operation by skipping over rows with a
TimeFilter index value higher than the value in the received
GetNext/GetBulk request. That is, instead of incrementing a
TimeFilter index value, the agent will continue to the next
object or table. As a consequence, GetNext or GetBulk
operations will provide only one pass through a time-filtered
table.
It is suggested for an agent to implement a time-filtered table
in this manner to improve performance and avoid a 'MIB walk'
getting stuck in time-filtered tables. It is, however, still
acceptable for an agent to implement a time-filtered table in
the traditional manner (i.e., every conceptual time-filtered
instance is returned in GetNext and GetBulk PDU responses) and
management applications must be able to deal with such
traditional implementations.
See the appendix for further discussion of this textual
convention.
The following example is provided to demonstrate TimeFilter
behavior:
Consider the following basic conceptual table basicFooTable
(Note that the basic version of a time-filtered table may not
actually be defined.)
basicFooTable:
basicFooTable ...
INDEX { fooIndex }
BasicFooEntry {
fooIndex Integer32,
fooCounts Counter32
}
For this example, the basicFooTable contains two static
conceptual entries (fooIndex equals '1' and '2'), created at
time zero. It also contains one dynamic conceptual entry
Steven Waldbusser Expires April 3, 2006 [Page 23]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
(fooIndex equals '3'), which is created at time '3' and deleted
at time '7'.
The time-filtered version of the basicFooTable could be defined
as follows:
FooTable:
fooTable ...
INDEX { fooTimeMark, fooIndex }
FooEntry {
fooTimeMark TimeFilter,
fooIndex Integer32,
fooCounts Counter32
}
Note that entries exist in the time-filtered conceptual table
only if they actually exist in the underlying (basic) table.
For this example, the fooTable will have three underlying
basic entries (fooIndex == 1, 2, and 3), with the following
activity (for sysUpTime equal 0 to 9):
- fooEntry.N.1 is created at time '0', and most recently
updated at time '6' to the value '5'.
- fooEntry.N.2 is created at time '0', and most recently
updated at time '8' to the value '9'.
- fooEntry.N.3 is created at time '3', updated at time '5'
to the value '17', and deleted at time '7'.
The following tables show the values that would be returned for
'MIB walk' operations with various TimeFilter values, done at
different times. An application issues a retrieval request at
time 'T', with a TimeFilter value 'N' (typically set to a lower
value, such as the value of sysUpTime at the last polling cycle).
The following values would be returned in a MIB walk of
fooCounts.N if T equals '0' and N equals '0':
fooCounts.N.I Value
==========================
fooCounts.0.1 0
Steven Waldbusser Expires April 3, 2006 [Page 24]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
fooCounts.0.2 0
Note there is nothing returned for fooCounts.0.3 since that
entry does not exist at sysUpTime equals '0'.
The following values would be returned in a full (traditional) MIB
walk of fooCounts.N if T equals '3' and N equals '0':
fooCounts.N.I Value
=======================
fooCounts.0.1 0
fooCounts.0.2 0
fooCounts.0.3 0
fooCounts.1.3 0
fooCounts.2.3 0
fooCounts.3.3 0
Note that there are no instances for T equals 1 or 2, for the
first two values of N, since these entries did not change
since they were created at time '0'.
Note that the current value for 'fooCounts.N.3' is returned
here, even for values of N less than '3' (when the entry was
created). The agent only considers the current existence of an
entry in the TimeFilter algorithm, not the time when the entry
was created.
Note that the instances 'fooCounts.0.3', 'fooCounts.1.3'
and 'fooCounts.2.3' are duplicates and can be suppressed by the
agent in a MIB walk.
The following values would be returned in a full (traditional)
MIB walk of fooCounts.N if T equals '6' and N equals '3':
fooCounts.N.I Value
=======================
fooCounts.3.1 5
fooCounts.3.3 17
fooCounts.4.1 5
fooCounts.4.3 17

fooCounts.5.3 17
fooCounts.6.1 5
Steven Waldbusser Expires April 3, 2006 [Page 25]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
Note that no instances for entry 'fooCounts.N.2' are returned
since it has not changed since time '3'.
Note that all instances except 'fooCounts.5.3' and
'fooCounts.6.1' are duplicates and can be suppressed by the
agent in a MIB walk.
The following values would be returned in a full (traditional)
MIB walk of fooCounts.N if T equals '9' and N equals '6':
fooCounts.N.I Value
=======================
fooCounts.6.1 5
fooCounts.6.2 9
fooCounts.7.2 9

Note that no instances for entry 'fooCounts.N.3' are returned

"This object describes 2 attributes of this protocol
directory entry.
The presence or absence of the `extensible' bit describes
whether or not this protocol directory entry can be extended
by the user by creating protocol directory entries which are
children of this protocol.
An example of an entry that will often allow extensibility is
`ip.udp'. The probe may automatically populate some children
of this node such as `ip.udp.snmp' and `ip.udp.dns'.
A probe administrator or user may also populate additional
children via remote SNMP requests that create entries in this

table. When a child node is added for a protocol for which the
probe has no built in support, extending a parent node (for
which the probe does have built in support),
that child node is not extendible. This is termed `limited
extensibility'.
When a child node is added through this extensibility
mechanism, the values of protocolDirLocalIndex and
protocolDirType shall be assigned by the agent.
The other objects in the entry will be assigned by the
manager who is creating the new entry.
This object also describes whether or not this agent can
recognize addresses for this protocol, should it be a network
level protocol. That is, while a probe may be able to
recognize packets of a particular network layer protocol and
count them, it takes additional logic to be able to recognize
the addresses in this protocol and to populate network layer
or application layer tables with the addresses in this
protocol. If this bit is set, the agent will recognize
network layer addresses for this protoocl and populate the
network and application layer host and matrix tables with
these protocols.
Note that when an entry is created, the agent will supply
values for the bits that match the capabilities of the agent
with respect to this protocol. Note that since row creations
usually exercise the limited extensibility feature, these
bits will usually be set to zero."

-- User History Collection Group (usrHistory)
--
-- The usrHistory group combines mechanisms seen in the alarm and
-- history groups to provide user-specified history collection,
-- utilizing two additional control tables and one additional data
-- table. This function has traditionally been done by NMS
-- applications, via periodic polling. The usrHistory group allows
-- this task to be offloaded to an RMON probe.
--
-- Data (an ASN.1 INTEGER based object) is collected in the same
-- manner as any history data table (e.g. etherHistoryTable) except
-- that the user specifies the MIB instances to be collected. Objects
-- are collected in bucket-groups, with the intent that all MIB
-- instances in the same bucket-group are collected as atomically as
-- possible by the RMON probe.
--
-- The usrHistoryControlTable is a one-dimensional read-create table.
-- Each row configures a collection of user history buckets, much
-- the same as a historyControlEntry, except that the creation of a
-- row in this table will cause one or more associated instances in
-- the usrHistoryObjectTable to be created. The user specifies the
-- number of bucket elements (rows in the usrHistoryObjectTable)
-- requested, as well as the number of buckets requested.
--
-- The usrHistoryObjectTable is a 2-d read-write table.
-- Each row configures a single MIB instance to be collected.
-- All rows with the same major index constitute a bucket-group.
--
-- The usrHistoryTable is a 3-d read-only table containing
-- the data of associated usrHistoryControlEntries. Each
-- entry represents the value of a single MIB instance
-- during a specific sampling interval (or the rate of
-- change during the interval).
--
-- A sample value is stored in two objects - an absolute value and
-- a status object. This allows numbers from -(2G-1) to +4G to be
-- stored. The status object also indicates whether a sample is
-- valid. This allows data collection to continue if periodic

-- retrieval of a particular instance fails for any reason.
--
-- Row Creation Order Relationships
--
-- The static nature of the usrHistoryObjectTable creates
-- some row creation/modification issues. The rows in this
-- table need to be set before the associated
-- usrHistoryControlEntry can be activated.
--
-- Note that the usrHistoryObject entries associated with a
-- particular usrHistoryControlEntry are not required to
-- be active before the control entry is activated. However,
-- the usrHistory data entries associated with an inactive
-- usrHistoryObject entry will be inactive (i.e.

mechanism, the probe must only grant write access to this

the probe. See USM [RFC3414] and VACM [RFC3415] for more

^c Delay for the number of seconds that follows. Toss
out any data received rather than storing it in a

by a smaller serialTimeout configured for the

^w Wait for the reply string that follows which is
terminated by the next command or the end of string.
Partial and case insensitive matching is applied, ie.
if the reply string (any case combination) is found
anywhere in the received string, then the a match is
found. If the current timeout elapses without a match,
then the remaining control string is ignored.
^! The ^ character.
^d Delay the number of seconds specified by the decimal
digits that follow.
^b Send break for the number of milliseconds specified by
the decimal digits that follow. If no digits follow,
break will be enforced for 250 milliseconds by default.
The following ASCII control characters may be inserted into
the `^s' send string or the `^w' reply string:

^M 0x0D

^Z 0x1A
^[ 0x1B
^ 0x1C

Binary data may also be inserted into the data stream. The
control sequence for each byte of binary data is ^0x##, where
## is the hexadecimal representation of the data byte. Two
ASCII characters (0-9, a-f, A-F) must follow the `^0x'

7. Security Considerations
In order to implement this MIB, a probe must capture all
packets on the locally-attached network, including packets
between third parties. These packets are analyzed to collect
network addresses, protocol usage information, and
conversation statistics. Data of this nature may be considered
sensitive in some environments. In such environments the
administrator may wish to restrict SNMP access to the probe.
The usrHistoryGroup periodically samples the values of user-
specified variables on the probe and stores them in another
table. Since the access-control specified for stored snapshot
may be different than the access-control for the sampled
variable, the agent MUST ensure that usrHistoryObjectVariable
is not writable in MIB views that don't already have read
access to the entire agent. Because the access control
configuration can change over time, information could later be
deemed sensitive that would still be accessible to this
function. For this reason, an agent SHOULD check the access
control on every sample. If an agent doesn't implement the
latter check, there is a potential for sensitive information
to be revealed.
A probe implementing this MIB is likely to also implement RMON
[RFC2819], which includes functions for returning the contents
of captured packets, potentially including sensitive user data
or passwords. It is recommended that SNMP access to these
functions be restricted.
There are a number of management objects defined in this MIB
that have a MAX-ACCESS clause of read-write and/or read-
create. Such objects may be considered sensitive or
vulnerable in some network environments. The support for SET
operations in a non-secure environment without proper
protection can have a negative effect on network operations.
Some of the readable objects in this MIB module (i.e., objects
with a MAX-ACCESS other than not-accessible) may be considered
sensitive or vulnerable in some network environments. It is
thus important to control even GET and/or NOTIFY access to
these objects and possibly to even encrypt the values of these
objects when sending them over the network via SNMP.
Steven Waldbusser Expires April 3, 2006 [Page 149]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
SNMP versions prior to SNMPv3 did not include adequate
security. Even if the network itself is secure (for example
by using IPSec), even then, there is no control as to who on
the secure network is allowed to access and GET/SET
(read/change/create/delete) the objects in this MIB module.
It is RECOMMENDED that implementers consider the security
features as provided by the SNMPv3 framework (see [RFC3410],
section 8), including full support for the SNMPv3
cryptographic mechanisms (for authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and
to enable cryptographic security. It is then a
customer/operator responsibility to ensure that the SNMP
entity giving access to an instance of this MIB module is
properly configured to give access to the objects only to
those principals (users) that have legitimate rights to indeed
GET or SET (change/create/delete) them.
8. IANA Considerations
No IANA actions are necessary.

Internet Draft Remote Network Monitoring MIB Oct 3, 2005
9. Appendix - TimeFilter Implementation Notes
1) Theory of Operation
The TimeFilter mechanism allows an NMS to reduce the number of
SNMP transactions required for a 'table-update' operation, by
retrieving only the rows that have changed since a specified
time (usually the last poll time). Polling of tables that
incorporate a 'TimeFilter' INDEX can be reduced to a
theoretical minimum (if used correctly). It can be easily
implemented by an agent in a way independent of the number of
NMS applications using the same time-filtered table.
Although the name 'TimeFilter' may imply that a history of
change events is maintained by the agent, this is not the
case. A time-filtered-value represents the current value of
the object instance, not the 'saved' value at the time
indicated by the TimeFilter INDEX value. Note that TimeFilter
objects only appear in INDEX clauses (always not-accessible),
so their value is never retrieved. By design, the actual value
of a TimeFilter instance is not in itself meaningful (it's not
a 'last-change-timestamp').
The TimeFilter is a boolean filtering function applied in
internal Get* PDU processing. If the 'last-change-time' of the
specified instance is less than the particular TimeFilter
INDEX value, then the instance is considered 'not-present',
and it is skipped for GetNext and GetBulk PDUs, or a
'noSuchInstance' exception is returned for Get PDUs.
For TimeFilter purposes:
- a row is created when an accessible column is created
within
the row.
- a column that is created or deleted causes the TimeFilter
to
to update the time-stamp, only because the value of the
column
is changing (non-existent <-> some value).
- a row is deleted when all accessible columns are deleted.
This
event is not detectable with TimeFilter, and deleted rows
are
not retrievable with SNMP.

Internet Draft Remote Network Monitoring MIB Oct 3, 2005
1.1) Agent Implementation of a Time-Filtered Table
In implementation, the time-filtered rows (one for each tick
of sysUpTime) are only conceptual. The agent simply filters a
real table based on:
* the current value of sysUpTime
* the TimeFilter value passed in the varbind
* the last-update timestamp of each requested row
(agent implementation requirement)
For example, to implement a time-filtered table row (e.g., set
of counters), an agent maintains a timestamp in a 32-bit
storage location, initialized to zero. This is in addition to
whatever instrumentation is needed for the set of counters.
Each time one of the counters is updated, the current value of
sysUpTime is recorded in the associated timestamp. If this is
not possible or practical, then a background polling process
must 'refresh' the timestamp by sampling counter values and
comparing them to recorded samples. The timestamp update must
occur within 5 seconds of the actual change event.
When an agent receives a Get, GetNext, or GetBulk PDU
requesting a time-filtered instance, after the agent has
determined that the instance is within the specified MIB view,
the following conceptual test is applied to determine if the
object is returned or filtered:
/* return TRUE if the object is present */
boolean time_filter_test (
TimeFilter last_modified_timestamp,
TimeFilter index_value_in_pdu )
{
if (last_modified_timestamp < index_value_in_pdu)
return FALSE;
else
return TRUE;
}
The agent applies this function regardless of the
lastActivationTime of the conceptual row in question. In other
words, counter discontinuities are ignored (i.e. conceptual
row deleted and then re-created later). An agent should
consider a object instance 'changed' when it is created
Steven Waldbusser Expires April 3, 2006 [Page 152]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
(either at restart time for scalars and static objects, or
row-creation-time for dynamic tables).
Note that using a timeFilter INDEX value of zero removes the
filtering functionality, as the instance will always be
'present' according to the test above.
After some deployment experience, it has been determined that
a time-filtered table is more efficient to use if the agent
stops a "MIB walk" operation after one time-filtered entry.
That is, a GetNext or GetBulk operation will provide one pass
through a given table, i.e., the agent will continue to the
next object or table, instead of incrementing a TimeMark INDEX
value, even if there exists higher TimeMark values which are
valid for the same conceptual row.
It is acceptable for an agent to implement a time-filtered
table in this manner or in the traditional manner (i.e., every
conceptual time-filtered instance is returned in GetNext and
GetBulk PDU responses).
1.2) NMS Implementation of a Time-Filtered Table
The particular TimeFilter INDEX values used by an NMS reflect
the polling interval of the NMS, relative to the particular
agent's notion of sysUpTime.
An NMS needs to maintain one timestamp variable per agent
(initialized to zero) for an arbitrary group of time-filtered
MIB objects that are gathered together in the same PDU. Each
time the Get* PDU is sent, a request for sysUpTime is
included. The retrieved sysUpTime value is used as the
timeFilter value in the next polling cycle. If a polling sweep
of a time-filtered group of objects requires more than one
SNMP transaction, then the sysUpTime value retrieved in the
first GetResponse PDU of the polling sweep is saved as the
next timeFilter value.
The actual last-update time of a given object is not indicated
in the returned GetResponse instance identifier, but rather
the timeFilter value passed in the Get*Request PDU is
returned.
A "time-filtered get-next/bulk-sweep", done once per polling
Steven Waldbusser Expires April 3, 2006 [Page 153]
Internet Draft Remote Network Monitoring MIB Oct 3, 2005
cycle, is a series of GetNext or GetBulk transactions, and is
over when one of the following events occurs:
1) the TimeFilter index value returned in the GetResponse is
different than the TimeFilter index value passed in the
GetNext or GetBulk request. Counter values will still be
returned beyond this point (until the last-change-time is
reached), but most likely the same values will be
returned.
2) the return PDU includes instances lexigraphically greater
than the objects expected (i.e. same GetNext semantics as
if the TimeFilter wasn't there)
3) a noSuchName or other exception/error is returned.
Note that the use of a time-filtered table in combination with
a GetRequest PDU neutralizes any optimization that otherwise
might be achieved with the TimeFilter. Either the current
time-filtered object-value is returned, or, if there is no
time-filtered object-value instance, then a 'noSuchInstance'
exception (SNMPv2c or SNMPv3) or 'noSuchName' error (SNMPv1)
is returned.
2) TimeFilter Example
The following example demonstrates how an NMS and Agent might
use a table with a TimeFilter object in the INDEX. A static
table is assumed to keep the example simple, but dynamic
tables can also be supported.
2.1) General Assumptions
fooEntry INDEX { fooTimeMark, fooIfIndex }
FooEntry = SEQUENCE {
fooTimeMark TimeFilter,
fooIfIndex Integer32,
fooCounts Counter32
}
The NMS polls the fooTable every 15 seconds and the
baseline poll occurs when the agent has been up for
6 seconds, and the NMS has been up for 10 seconds.
There are 2 static rows in this table at system
initialization (fooCounts.0.1 and fooCounts.0.2).

10. Changes since RFC 2021
This version updates the proposed-standard version of the
RMON2 MIB (published as RFC 2021) by adding 2 new enumerations
to the nlMatrixTopNControlRateBase object and 4 new
enumerations to the alMatrixTopNControlRateBase object. These
new enumerations support the creation of high capacity topN
reports in the High Capacity RMON MIB [RFC3273].
Additionally, the following objects have been deprecated as

they have not had enough independent implementations to
demonstrate interoperability to meet the requirements of a

In addition, two corrections were made. The LastCreateTime
Textual Convention had been defined with a base type of
another textual convention which isn't allowed in SMIv2. The
definition has been modified to use TimeTicks as the base
type.
Further, the SerialConfigEntry SEQUENCE definition included
sub-typing information that is not allowed in SMIv2. This
information has been deleted. Ranges were added to a number of
objects and textual-conventions to constrain their maximum
(and sometimes minimum) sizes. The addition of these ranges
documents existing practice for
these objects. These objects are:
ControlString
protocolDirID
protocolDirParameters
addressMapNetworkAddress
nlHostAddress
nlMatrixSDSourceAddress
nlMatrixSDDestAddress
nlMatrixDSSourceAddress
nlMatrixDSDestAddress
nlMatrixTopNSourceAddress
nlMatrixTopNDestAddress
alHostEntry
alMatrixSDEntry
alMatrixDSEntry
alMatrixTopNSourceAddress
alMatrixTopNDestAddress
Finally, the TimeFilter TC has been updated to encourage agent
implementations that allow a MIB walk to behave well even when
performed by an application that is not aware of the special
TimeFilter semantics.
