1. The SNMP Network Management Framework
-
The SNMP Management Framework presently consists of five major components:
- 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].
- 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].
- 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].
- 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.
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.
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.
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'.

- 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.
- 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.
- 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.
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).
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.
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.
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.

-
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 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.

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.
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");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");
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.2.2 = createAndGo(4), dsmonAggGroupDescr.2.2 = "CS2"); SET(dsmonAggGroupStatus.2.3 = createAndGo(4), dsmonAggGroupDescr.2.3 = "CS3"); SET(dsmonAggGroupStatus.2.4 = createAndGo(4), dsmonAggGroupDescr.2.4 = "CS4"); SET(dsmonAggGroupStatus.2.5 = createAndGo(4), dsmonAggGroupDescr.2.5 = "CS5"); 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), dsmonAggGroupDescr.2.13 = "AF22"); SET(dsmonAggGroupStatus.2.14 = createAndGo(4), dsmonAggGroupDescr.2.14 = "AF23"); SET(dsmonAggGroupStatus.2.15 = createAndGo(4), dsmonAggGroupDescr.2.15 = "AF31"); SET(dsmonAggGroupStatus.2.16 = createAndGo(4), dsmonAggGroupDescr.2.16 = "AF32"); SET(dsmonAggGroupStatus.2.17 = createAndGo(4), dsmonAggGroupDescr.2.17 = "AF33"); SET(dsmonAggGroupStatus.2.18 = createAndGo(4), dsmonAggGroupDescr.2.18 = "AF41"); 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");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.

5.7. Step 7: Lock the Counter Aggregation Configuration
-
Before any existing collections can be activated by the agent, the counter aggregation configuration must be locked, by setting the dsmonAggControlLocked scalar to 'true'.
SET(dsmonAggControlLocked.0 = true(1));

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.
