1. The SNMP Network Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [RFC2571].
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and is described in
STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC
1215 [RFC1215]. The second version, called SMIv2, is described in
STD 58, RFC 2578 [RFC2578], RFC 2579 [RFC2579] and RFC 2580
[RFC2580].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and is
described in STD 15, RFC 1157 [RFC1157]. A second version of the
SNMP message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and is described in RFC 1901 [RFC1901]
and RFC 1906 [RFC1906]. The third version of the message protocol
is called SNMPv3 and is described in RFC 1906 [RFC1906], RFC 2572
[RFC2572] and RFC 2574 [RFC2574].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC 1157 [RFC1157]. A second set of protocol
operations and associated PDU formats is described in RFC 1905
[RFC1905].
Bierman Standards Track [Page 2]
RFC 3287 DSMON MIB July 2002
o A set of fundamental applications described in RFC 2573 [RFC2573]
and the view-based access control mechanism described in RFC 2575
[RFC2575].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [RFC2570].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.
2. Overview
There is a need for a standardized way of monitoring the network
traffic usage of Differentiated Services (DS) [RFC2474] codepoint
values. Each DS codepoint (DSCP) value may be given a different
treatment by a forwarding device, and this affects which packets get
dropped or delayed during periods of network congestion.
The IETF DIFFSERV working group has redefined the semantics of the
Type of Service (TOS) octet in the IP header, which is now called the
'DS field'. The 6-bit Codepoint (DSCP) portion is contained in the
DS field, which provides for 64 different packet treatments for the
implementation of differentiated network services.
By polling DSCP usage counters, an NMS can determine the network
throughput for traffic associated with different DSCPs. This data
can then be analyzed in order to 'tune' DSCP 'allocations' within a
network, based on the Quality of Service (QoS) policies for that
network.
Remote monitoring agents are typically implemented as independent
software (and sometimes hardware) components, called 'RMON probes'.
Note that DSMON-capable RMON probes simply collect and aggregate
statistics, based on criteria (which includes the DSCP value) that
can be determined by inspecting the contents of monitored packets and
do not in any way monitor any aspect of a DS forwarding device's
internal statistics.
Bierman Standards Track [Page 3]
RFC 3287 DSMON MIB July 2002
2.1. Terms
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in BCP 14, RFC 2119.
[RFC2119]
This document uses some terms that need introduction:
DataSource
A source of data for monitoring purposes. This term is used
exactly as defined in the RMON-2 MIB [RFC2021].
protocol
A specific protocol encapsulation, as identified for monitoring
purposes. This term is used exactly as defined in the RMON
Protocol Identifiers document [RFC2074].
Counter Aggregation Group
A group of statistical counters that are being combined in the
agent to produce one aggregated counter. Refer to sections 3.1
and 3.2.1 for details on counter aggregation groups.
Counter Aggregation Profile
Also called 'profile'; A complete set of counter aggregation group
mappings for DSCP values (i.e., 64 mappings, for each DSCP values
0 to 63), which are applied to all monitored packets on a
particular data source and/or DSMON collection. Refer to sections
3.1 and 3.2.1 for details on counter aggregation profiles.
High Capacity Monitoring
The generic capability to collect and store statistics with an
internal range of 64 bits (e.g., Counter64). This term does not
refer to implementation of the High Capacity RMON MIB [RFC3273].
2.2. Relationship to Differentiated Services
The DSMON MIB is a product of the RMONMIB WG, not the DIFFSERV WG,
and it focuses on extending several existing RMON mechanisms to
support additional packet classification, based on DSCP values
observed in monitored packets. This document assumes the reader is
familiar with the DS Architecture [RFC2475].
It is expected that complex management applications will use the
counters in this MIB to help analyze DS-related throughput. It is
expected that other metrics, such as delay and jitter, will also be
analyzed, but support for other metrics is outside the scope of this
document.
Bierman Standards Track [Page 4]
RFC 3287 DSMON MIB July 2002
2.3. Relationship to the Remote Monitoring MIBs
This MIB is intended to be implemented in Remote Monitoring (RMON)
probes, which support the RMON-2 MIB [RFC2021]. Such probes may be
stand-alone devices, or may be co-located with other networking
devices (e.g., ethernet switches and repeaters).
The DSMON functions are intended to be implemented in conjunction
with the associated RMON functions, but the MIB is independent of all
other RMON data tables.
Several concepts and even MIB objects from the RMON MIBs are used in
the DSMON MIB:
Protocol Directory
The RMON-2 MIB [RFC2021] defines the protocolDirTable, which is a
directory of all the protocols that the RMON-2 agent is capable of
decoding and counting. The DSMON MIB utilizes this directory to
identify the protocols detected in monitored packets. The
protocolDirLocalIndex MIB object is used to identify protocol
encapsulations in all DSMON data tables which classify and
aggregate by protocol type in some manner. Note that the
protocolDirTable is used for protocol identification only,
independent of DSCP classification.
TimeFilter
The RMON-2 TimeFilter textual convention provides a mechanism to
retrieve only rows which have been created or modified since the
last polling interval (for a particular NMS). The DSMON MIB uses
this textual convention in the large data tables, in order to
minimize polling impact.
Zero-Based Counters
Since counters are instantiated by management action, as in the
RMON MIBs, the DSMON MIB uses zero-based counters in all data
collection tables. Specifically, the ZeroBasedCounter32 textual
convention from the RMON-2 MIB [RFC2021] and the
ZeroBasedCounter64 textual convention (defined in the HCNUM-TC MIB
[RFC2856]) are used to define counter objects in this MIB.
High Capacity Counters
The DSMON MIB uses the 'SNMPv1 coexistence' strategy adopted by
the RMONMIB WG. That is, where a 64-bit counter is provided, a
32-bit version of the counter, and a 32-bit overflow counter are
also provided.
Bierman Standards Track [Page 5]
RFC 3287 DSMON MIB July 2002
TopN Reports
The DSMON MIB uses the same TopN reporting MIB structure as the
RMON-2 MIB [RFC2021]. TopN reporting can greatly reduce the
polling overhead required to analyze DSCP usage patterns.
Some DESCRIPTION clauses for DSMON objects are very similar to those
for existing RMON-2 or HC-RMON objects. This is intentional, since
the semantics of the DSMON features are designed to be as close to
existing RMON feature as possible, to allow developers and users some
level of 'MIB re-use'.

Bierman Standards Track [Page 6]
RFC 3287 DSMON MIB July 2002
The DSMON MIB can divided into three functional components:
- DSMON Capabilities
Describes which DSMON object groups are supported by the agent on
at least one data source.
- Counter Aggregation Control
Controls how individual DIFFSERV codepoint counters are aggregated
in DSMON data collections.
- Data Collection
Controls how individual statistical collections are maintained by
the agent and reported to management applications. The individual
boxes within the Data Collection box represent the DSMON data
collections (described in section 3.2):
- Data Source Statistics
- Protocol Statistics
- Protocol Statistics TopN Reporting
- Network Protocol Host Statistics
- Network Protocol Host Statistics TopN Reporting
- Application Protocol Matrix Statistics
- Application Protocol Matrix Statistics TopN Reporting
3.1. DSCP Counter Aggregation
A mechanism to configure the agent to internally aggregate counters
is provided, based on DSCP values. This is desirable for several
reasons:
- agent data reduction
An agent implementation can potentially reduce the number of
counters maintained for a given DSMON collection.
- agent data collection limitations
Some implementation strategies might provide for a limited number
of high-speed (e.g., hardware-based) counters for either single or
aggregated codepoints.
- application data retrieval reduction
Applications that would otherwise aggregate counters for
individual codepoints can move that function to the agent in order
to reduce the polling overhead on the application, the network,
and the agent device.
- some unused codepoints at this time
Various DSCP values may be expected to remain unused on a given
network, and may be aggregated for counting purposes.
Bierman Standards Track [Page 7]
RFC 3287 DSMON MIB July 2002
- some DSCP values are mapped to the same packet treatment
A network administrator may align the counter aggregation
configuration of the monitoring device with the DS configuration,
and aggregate statistics for DSCP values which are expected to
receive the same treatment by the forwarding devices.
3.1.1. Counter Aggregation Configuration
The configuration of DSCP counter to counter aggregation group
mappings is managed in a global manner, so that these settings can be
shared across several DSMON collections and/or data sources. One
complete set of DSCP counter mappings is called a counter aggregation
profile. The DSMON control tables are very similar to existing
RMON-2 control tables, except they contain an extra parameter to
identify the counter aggregation profile the agent should use for the
collection.
The appropriate granularity for counter aggregation profile
assignment may be the data source, but in order to reduce MIB
complexity (by avoiding an extra layer of tables), an instance of the
counter aggregation profile parameter exists for each collection. An
agent MAY choose to restrict configurations such that all DSMON data
collections for the same data source must use the same counter
aggregation profile.
The DSMON MIB supports the configuration of an arbitrary number of
counter aggregation profiles. There is a top-level counter
aggregation control table, which contains one entry for each counter
aggregation profile. A subordinate counter aggregation profile table
provides information about each DSCP counter to counter aggregation
group mapping in each profile. An auxiliary counter aggregation
group table also provides descriptive information about each counter
aggregation group in each profile. Refer to section 3.2.1 for
details on these MIB objects.
3.2. MIB Group Overview
The DSMON MIB contains six groups of MIB objects:
- dsmonAggregateControl group
Controls the configuration of counter aggregation groups for the
purpose of reducing the total number of counters maintained by the
agent.
- dsmonStatsObjects group
Report per counter aggregation group distribution statistics for a
particular RMON dataSource.
Bierman Standards Track [Page 8]
RFC 3287 DSMON MIB July 2002
- dsmonPdistObjects group
Report per counter aggregation group distribution statistics for
each application protocol detected on a particular RMON
dataSource.
- dsmonHostObjects group
Report host address distribution statistics for each counter
aggregation group, detected on a particular RMON dataSource.
- dsmonCapsObjects group
Report the static DSMON MIB functional capabilities of the agent
implementation.
- dsmonMatrixObjects group
Report host address pair distribution statistics for each counter
aggregation group, detected on a particular RMON dataSource.
3.2.1. DSCP Counter Aggregation Control Group
This group contains 4 scalar objects and three tables, and is used by
a management station to configure counter aggregation profiles.
The dsmonMaxAggGroups scalar is a read-only integer which indicates
the maximum number of counter aggregation groups that the agent will
allow to be configured into a single aggregation profile. This value
SHOULD be equal to 64 (the number of codepoints), but an agent MAY
limit the number of counter aggregation groups because of resource
limitations (e.g., small number of hardware-based counters). At
least one counter aggregation profile containing at least two counter
aggregation groups SHOULD be supported by the agent. (Note that
classifying all DSCP counters into the same statistical 'bucket' may
yield a redundant data collection, which can be achieved more easily
with an HC-RMON or RMON-2 collection instead.)
The dsmonAggControlLocked scalar is used as a top level switch,
controlling most write access to the dsmonAggControlTable,
dsmonAggProfileTable, and dsmonAggGroupTable. (The
dsmonAggControlOwner object is the only exception.) All active DSMON
collection data is deleted, and collection suspended, while this
object is equal to 'false', since the meaning of one or more counter
aggregation control tables may change when it is set back to 'true'.
The dsmonAggControlChanges counter and dsmonAggControlLastChangeTime
timestamp can be used by a management station to detect that the
codepoint to counter aggregation group mappings may have changed
between polls.
Bierman Standards Track [Page 9]
RFC 3287 DSMON MIB July 2002
The dsmonAggControlTable is a read-create table which contains one
entry for each counter aggregation profile configured on the agent.
Each entry is identified by a dsmonAggControlIndex value, which is
also used as the major index into the dsmonAggProfileTable and
dsmonAggGroupTable. The DSMON control tables with DataSource objects
select a counter aggregation profile by referencing this index value.
The dsmonAggProfileTable is a read-write table which contains 64 rows
for each associated entry in the dsmonAggControlTable, which MUST be
indexed from 0 to 63. The agent creates this set of 64 instances
when the associated dsmonAggControlEntry is activated, and deletes
them when that dsmonAggControlEntry is deactivated. Each of the 64
rows represents a conceptual DSCP counter, identified by the same
dsmonAggProfileDSCP value, and contains the DSCP counter to counter
aggregation group mapping for that DSCP counter, in the indicated
profile. The agent SHOULD use the value zero as the initial counter
aggregation group assignment for each entry in this table.
The dsmonAggGroupTable contains an administratively assigned
descriptive label for each configured counter aggregation group.
This table is not required to be fully configured in order for data
collection to occur, since collections are identified by the agent
with integer indices. It is provided to allow the agent to store a
descriptive string for each configured counter aggregation group.
There is no attempt made to convey any real semantics for each
counter aggregation group. A management station MAY choose not to
configure entries in this table.
3.2.2. DS Statistics Group
This group contains two tables, the dsmonStatsControlTable and the
dsmonStatsTable, and supports counter aggregation group distribution
statistics for half and full-duplex, low and high speed interfaces.
Packet and octets distributions are maintained in the dsmonStatsTable
for each active control row in the dsmonStatsControlTable.
This group provides the lowest statistics granularity in the DSMON
MIB. It is expected that a management application will analyze
certain DS deployment or performance problems by first examining the
counter aggregation group distribution for an entire data source with
this group.
3.2.3. DS Protocol Distribution Group
This group contains two tables for statistics collection,
(dsmonPdistCtlTable and dsmonPdistStatsTable), and two tables for a
'Top N' reporting function for the collected statistics
(dsmonPdistTopNCtlTable and dsmonPdistTopNTable).
Bierman Standards Track [Page 10]
RFC 3287 DSMON MIB July 2002
The dsmonPdistCtlTable and dsmonPdistStatsTable tables provide
counter aggregation group distribution statistics for each selected
protocol encapsulation in packets monitored on a particular
dataSource. Packet and octets distributions (per counter aggregation
group per protocol) are maintained in the dsmonPdistStatsTable for
each active control row in the dsmonPdistCtlTable.
Due to the potentially large number of entries, the DS Protocol
Distribution is different from the RMON-2 protocol distribution group
in several ways:
- maximum desired entries parameter added to the control table
- inserts and deletes counters added to the control table
- support for LRU garbage collection in the dsmonPdistStatsTable
- TimeFilter index added to the dsmonPdistStatsTable
- the selection of protocols is not configurable. Rather than
select individual protocols to monitor, (e.g., via a
'supportedOn/Off' extension to the protocolDirTable [RFC 2021]), a
simplified configuration mechanism is provided. Since DSCP usage
statistics are most interesting at the application layer, the
dsmonPdistStatsTable is 'hardwired' to select only application
layer (i.e., 'terminal') protocols for statistical analysis.
The TopN feature requires two additional tables: the
dsmonPdistTopNCtlTable and the dsmonPdistTopNTable, and supports
periodic usage reporting for the statistics maintained in the
dsmonPdistStatsTable. This feature allows for simple periodic
retrieval of the most used application/counter aggregation group
combinations.
3.2.4. DS Host Distribution Group
This group contains two tables for statistics collection,
(dsmonHostCtlTable and dsmonHostTable), and two tables for a 'Top N'
reporting function for the collected statistics
(dsmonHostTopNCtlTable and dsmonHostTopNTable).
The dsmonHostCtlTable and dsmonHostTables provide host distribution
statistics for each counter aggregation group detected in packets
monitored on a particular dataSource. The DSMON Host collection is
similar to the RMON-2 network layer host collection (nlHostTable).
There is no DSMON application host table defined at this time.
Bierman Standards Track [Page 11]
RFC 3287 DSMON MIB July 2002
It is expected that a management application will analyze certain DS
deployment or performance problems by first determining the high
priority DSCP values to examine (beyond the scope of this document)
and then examining the dsmonHostTable or dsmonHostTopNTable
statistics to determine which hosts are using the selected counter
aggregation groups.
Packet and octets distributions (in and out, per counter aggregation
group per host) are maintained in the dsmonHostTable for each active
control row in the dsmonHostCtlTable.
The DS Host Distribution is different from the RMON-2 network layer
host group in two ways:
- the protocolDirLocalIndex in the INDEX clause MUST identify a
network protocol encapsulation which contains a DS field (e.g.,
IPv4 or IPv6). If a protocol encapsulation with multiple network
layers is specified, then associated entries in this table refer
to the innermost network protocol layer.
- the dsmonHostCtlTable supports limited IPv4 and IPv6 prefix
aggregation by allowing the number of 'monitored address bits' in
each address to be configured for each collection. The agent will
zero out the selected number of rightmost address bits for
counting purposes. This configuration parameter can dramatically
reduce the number of entries which must be maintained by the
agent, which should reduce CPU and memory resource requirements on
the agent, and reduce polling overhead on the network and the
management station. However, only one mask can be configured for
each address type, rather than multiple different length masks for
each address type, based on prefix value.
The TopN feature requires two additional tables: the
dsmonHostTopNCtlTable and the dsmonHostTopNTable, and supports
periodic usage reporting for the statistics maintained in the
dsmonHostTable. This feature allows for simple periodic retrieval of
the most used IP-host/DSCP combinations.
3.2.5. DSMON Capabilities Group
This group contains a single read-only scalar object,
dsmonCapabilities, which provides an indication of the MIB groups
within this MIB that the agent supports.
Bierman Standards Track [Page 12]
RFC 3287 DSMON MIB July 2002
3.2.6. DS Matrix Distribution Group
This group contains three tables for statistics collection,
(dsmonMatrixCtlTable, dsmonMatrixSDTable, and dsmonMatrixDSTable),
and two tables for a 'Top N' reporting function for the collected
statistics (dsmonMatrixTopNCtlTable and dsmonMatrixTopNTable).
The dsmonMatrixCtlTable, dsmonMatrixSDTable, and dsmonMatrixDSTable
provide host-pair distribution statistics for each counter
aggregation group detected in packets monitored on a particular
dataSource. The DSMON Matrix collection is similar to the RMON-2
application layer matrix collection (alMatrixSDTable and
alMatrixDSTable). There is no DSMON network layer matrix table
defined at this time.
It is expected that a management application will analyze certain DS
deployment or performance problems by first determining the high
priority DSCP values to examine (beyond the scope of this document)
and then examining the dsmonMatrixSDTable, dsmonMatrixDSTable, and/or
dsmonMatrixTopNTable statistics to determine which host-pairs are
using the selected counter aggregation groups.
Packet and octets distributions (source to destination, per counter
aggregation group per host-pair) are maintained in the
dsmonMatrixSDTable and dsmonMatrixDSTable for each active control row
in the dsmonMatrixCtlTable.
The TopN feature requires two additional tables: the
dsmonMatrixTopNCtlTable and the dsmonMatrixTopNTable, and supports
periodic usage reporting for the statistics maintained in the
dsmonMatrixSDTable. This feature allows for simple periodic
retrieval of the most used IP-host-pair/DSCP combinations.
3.3. RMON vs. DSMON Indexing Structure
The DSMON-MIB control and data tables are very similar in structure
and look-and-feel to existing RMON-2 and HC-RMON control tables for
the comparable feature, in order to maintain consistent agent
behavior and functionality across RMON MIBs. The DSMON data tables
are indexed as closely as possible to the comparable RMON-2 or HC-
RMON tables, with the addition of an index component for DSCP-based
classification (i.e. dsmonAggGroup). Refer to Table 1 for a
comparison of DSMON indexing structure with similar existing RMON
features.

"This TC describes a data type which identifies a DSMON
counter aggregation group, which is an arbitrary grouping of
conceptual counters, for monitoring purposes only. The
range for this data type begins with zero (instead of
one), to allow for a direct mapping between counter
indexing schemes that start at zero (e.g. DSCP values in
packets) and counter aggregation group values."

SYNTAX TruthValue
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"Controls the setup of counter aggregation groups for this
agent.
If this object contains the value 'true', then write access
to the objects in the dsmonAggControlTable (except the
dsmonAggControlOwner object), dsmonAggProfileTable, and
dsmonAggGroupTable is not permitted, and data collection is
possible. This object only controls write access to these
MIB objects. The DSMON data collection control tables
(e.g., dsmonHostCtlTable) can be configured at any time,
regardless of the value of this object.
If this object contains the value 'false', write access to
the objects in the dsmonAggControlTable,
dsmonAggProfileTable, and dsmonAggGroupTable is permitted,
and data collection is not possible. In addition, all
objects in all DSMON data tables (e.g., dsmonStatsTable)
shall be deleted.
An agent is not required to process SNMP Set Requests for
this object in conjunction with other objects from this MIB.
This is intended to simplify the processing of Set Requests
for tables such as the dsmonAggProfileTable, by eliminating
the possibility that a single Set PDU will contain multiple
varbinds which are in conflict, such as a PDU which both
modifies the dsmonAggProfileTable and locks the
Bierman Standards Track [Page 19]
RFC 3287 DSMON MIB July 2002
dsmonAggProfileTable at the same time.
Note that the agent is not required to validate the entire
counter aggregation configuration when an attempt is made to
transition an instance of this object from 'true' to
'false'. That validation is done if and when a DSMON data
collection is activated.
An agent is required to reactivate any suspended data
collections when this object transitions to 'true', Each
active data control entry (e.g., dsmonStatsControlEntry),
will be validated with respect to the new counter
aggregation configuration. If the counter aggregation
profile referenced in the data collection is valid, then
that collection will be restarted. Otherwise, the RowStatus
object (e.g., dsmonStatsControlStatus) will be set to
'notReady' for that collection control entry."

A management application SHOULD create a counter aggregation
profile by first creating and activating an entry in this

dsmonAggProfileEntries on behalf of this control entry. An
application can then set the individual counter aggregation
group assignments for each of the 64 DSCP values,
This table MUST NOT be modified if the dsmonAggControlLocked
object is equal to 'true'.
Note that an agent MAY choose to limit the actual number of
entries which may be created in this table, and
(independently) the number of counter aggregation profiles
which may be applied to a particular data source. In this
case, the agent SHOULD return an error-status of
'resourceUnavailable(13)', as per section 4.2.5 of the
'Protocol Operations for SNMPv2' specification [RFC1905].
The agent SHOULD support non-volatile configuration of this

DESCRIPTION
"The number of seconds left in the report currently being

station, a new collection is started, possibly aborting a
currently running report. The new value is used as the
requested duration of this report, and is immediately loaded
into the associated dsmonMatrixTopNCtlDuration object.
When the report finishes, the probe will automatically start
another collection with the same initial value of
dsmonMatrixTopNCtlTimeRemaining. Thus the management
station may simply read the resulting reports repeatedly,
checking the startTime and duration each time to ensure that
a report was not missed or that the report parameters were
not changed.
While the value of this object is non-zero, it decrements by
one per second until it reaches zero. At the time that this
object decrements to zero, the report is made accessible in
the dsmonMatrixTopNTable, overwriting any report that may be
there.
When this object is modified by the management station, any

5. Counter Aggregation Configuration Usage Examples
This section contains an example of the steps that may be followed by
a management station to configure the objects in the
dsmonCounterAggControlGroup.
A note about these examples:
- they do not define a standard
- an agent is not obligated to support them
- a management application is not constrained by them
- the SET(object = value [, ...]) notation is only conceptual, and
is not meant to represent an actual SNMP Set PDU.
Bierman Standards Track [Page 108]
RFC 3287 DSMON MIB July 2002
5.1. Step 1: Unlock the Counter Aggregation Configuration
Before any write operations to the tabular objects in this group can
be made, the counter aggregation configuration must be unlocked by
setting the dsmonAggControlLocked scalar to false:
SET(dsmonAggControlLocked.0 = false(2));
5.2. Step 2: Check the Maximum number of Counter Aggregation Groups
Make sure the desired counter aggregation groups have a chance of
being configured on the agent.
maxGroups = GET(dsmonAggMaxAggGroups.0);
For this example, maxGroups is greater or equal to 64.
5.3. Step 3: Check if the counter aggregation profiles already exist
Make sure the desired counter aggregation profiles have not already
been configured, or perhaps recreated after an agent restart. The
following example is oversimplified, in that the entire counter
aggregation configuration should actually be verified.
profile1Descr = GET(dsmonAggControlDescr.1);
profile1Owner = GET(dsmonAggControlOwner.1);
profile1Status = GET(dsmonAggControlStatus.1);
For this example, none of the counter aggregation profiles already
exist.
5.4. Step 4: Create the Counter Aggregation Control Entries
The management station should create one entry in the
dsmonAggControlTable for each counter aggregation profile to be
configured on the agent.
Steps 4, 5, and 6 are repeated for each counter aggregation profile
to be configured on the agent. There are 3 example counter
aggregation profiles shown in each of these steps.
Example 1: Each DSCP in its own counter aggregation group.
SET(dsmonAggControlStatus.1 = createAndGo(4),
dsmonAggControlOwner.1 = "Example App 1",
dsmonAggControlDescr.1 = "1 DSCP Per Group");
Bierman Standards Track [Page 109]
RFC 3287 DSMON MIB July 2002
Example 2: a collection of DIFFSERV PHBs.
SET(dsmonAggControlStatus.2 = createAndGo(4),
dsmonAggControlOwner.2 = "Example App 2",
dsmonAggControlDescr.2 = "June 2000 DIFFSERV PHBs");
Example 3: an aggregated collection of DIFFSERV PHBs.
SET(dsmonAggControlStatus.3 = createAndGo(4),
dsmonAggControlOwner.3 = "Example App 3",
dsmonAggControlDescr.3 = "Limited June 2000 PHBs");
5.5. Step 5: Create the Counter Aggregation Group Descriptions
Example 1: Each DSCP in its own counter aggregation group. One group
is created for each codepoint, for a total of 64 rows.
SET(dsmonAggGroupStatus.1.0 = createAndGo(4),
dsmonAggGroupDescr.1.0 = "DSCP 0");
SET(dsmonAggGroupStatus.1.1 = createAndGo(4),
dsmonAggGroupDescr.1.1 = "DSCP 1");
SET(dsmonAggGroupStatus.1.2 = createAndGo(4),
dsmonAggGroupDescr.1.2 = "DSCP 2");
SET(dsmonAggGroupStatus.1.3 = createAndGo(4),
dsmonAggGroupDescr.1.3 = "DSCP 3");
...
SET(dsmonAggGroupStatus.1.63 = createAndGo(4),
dsmonAggGroupDescr.1.63 = "DSCP 63");
Bierman Standards Track [Page 110]
RFC 3287 DSMON MIB July 2002
Example 2: a collection of current DIFFSERV PHBs. One group is
created for each PHB to be monitored.
SET(dsmonAggGroupStatus.2.0 = createAndGo(4),
dsmonAggGroupDescr.2.0 = "CS0");
SET(dsmonAggGroupStatus.2.1 = createAndGo(4),
dsmonAggGroupDescr.2.1 = "CS1");

SET(dsmonAggGroupStatus.2.6 = createAndGo(4),
dsmonAggGroupDescr.2.6 = "CS6");
SET(dsmonAggGroupStatus.2.7 = createAndGo(4),
dsmonAggGroupDescr.2.7 = "CS7");
SET(dsmonAggGroupStatus.2.8 = createAndGo(4),
dsmonAggGroupDescr.2.8 = "EF");
SET(dsmonAggGroupStatus.2.9 = createAndGo(4),
dsmonAggGroupDescr.2.9 = "AF11");
SET(dsmonAggGroupStatus.2.10 = createAndGo(4),
dsmonAggGroupDescr.2.10 = "AF12");
SET(dsmonAggGroupStatus.2.11 = createAndGo(4),
dsmonAggGroupDescr.2.11 = "AF13");
SET(dsmonAggGroupStatus.2.12 = createAndGo(4),
dsmonAggGroupDescr.2.12 = "AF21");
SET(dsmonAggGroupStatus.2.13 = createAndGo(4),

SET(dsmonAggGroupStatus.2.19 = createAndGo(4),
dsmonAggGroupDescr.2.19 = "AF42");
SET(dsmonAggGroupStatus.2.20 = createAndGo(4),
dsmonAggGroupDescr.2.20 = "AF43");
SET(dsmonAggGroupStatus.2.21 = createAndGo(4),
dsmonAggGroupDescr.2.21 = "Nonzero Default");
Bierman Standards Track [Page 111]
RFC 3287 DSMON MIB July 2002
Example 3: an aggregated representation of current DIFFSERV PHBs.
One group is created for each counter aggregation to be monitored (8
rows in this example).
SET(dsmonAggGroupStatus.3.0 = createAndGo(4),
dsmonAggGroupDescr.3.0 = "Zero CS");
SET(dsmonAggGroupStatus.3.1 = createAndGo(4),
dsmonAggGroupDescr.3.1 = "Nonzero CS");
SET(dsmonAggGroupStatus.3.2 = createAndGo(4),
dsmonAggGroupDescr.3.2 = "EF");
SET(dsmonAggGroupStatus.3.3 = createAndGo(4),
dsmonAggGroupDescr.3.3 = "AF1");
SET(dsmonAggGroupStatus.3.4 = createAndGo(4),
dsmonAggGroupDescr.3.4 = "AF2");
SET(dsmonAggGroupStatus.3.5 = createAndGo(4),
dsmonAggGroupDescr.3.5 = "AF3");
SET(dsmonAggGroupStatus.3.6 = createAndGo(4),
dsmonAggGroupDescr.3.6 = "AF4");
SET(dsmonAggGroupStatus.3.7 = createAndGo(4),
dsmonAggGroupDescr.3.7 = "Nonzero Default");
5.6. Step 6: Create the Counter Aggregation Profile Mappings
After the dsmonAggControlEntries are activated, the associated read-
write dsmonAggProfileEntries will be created. The management station
must create 64 entries in the dsmonAggProfileTable for each counter
aggregation profile configured in the dsmonAggControlTable.
Example 1: Each DSCP in its own counter aggregation group
SET(dsmonAggGroupIndex.1.0 = 0,
dsmonAggGroupIndex.1.1 = 1,
dsmonAggGroupIndex.1.2 = 2,
dsmonAggGroupIndex.1.3 = 3,
...
dsmonAggGroupIndex.1.63 = 63);
Example 2: a collection of current DIFFSERV PHBs.
SET(dsmonAggGroupIndex.2.0 = 0, -- CS0
dsmonAggGroupIndex.2.1 = 21, -- Nonzero Default
dsmonAggGroupIndex.2.2 = 21,

9. 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.
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.
SNMPv1 by itself is not a secure environment. 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.
It is recommended that the implementors consider the security
features as provided by the SNMPv3 framework. Specifically, the use
of the User-based Security Model RFC 2574 [RFC2574] and the View-
based Access Control Model RFC 2575 [RFC2575] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, 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.
