DIFFSERV-MIB device MIB details by RFC
DIFFSERV-MIB file content
The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.
Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

The Conceptual Model of a Differentiated Services Router provides supporting information on how such a router is modeled." REVISION "200202070000Z" DESCRIPTION "Initial version, published as RFC 3289." ::= { mib-2 97 } diffServMIBObjects OBJECT IDENTIFIER ::= { diffServMib 1 } diffServMIBConformance OBJECT IDENTIFIER ::= { diffServMib 2 } diffServMIBAdmin OBJECT IDENTIFIER ::= { diffServMib 3 } IndexInteger ::= TEXTUAL-CONVENTION DISPLAY-HINT "d" STATUS current DESCRIPTION "An integer which may be used as a table index." SYNTAX Unsigned32 (1..4294967295) IndexIntegerNextFree ::= TEXTUAL-CONVENTION DISPLAY-HINT "d" STATUS current DESCRIPTION "An integer which may be used as a new Index in a table. The special value of 0 indicates that no more new entries can be created in the relevant table. When a MIB is used for configuration, an object with this SYNTAX always contains a legal value (if non-zero) for an index that is not currently used in the relevant table. The Command Generator (Network Management Application) reads this variable and uses the (non-zero) value read when creating a new row with an SNMP SET. When the SET is performed, the Command Responder (agent) must determine whether the value is indeed still unused; Two Network Management Applications may attempt to create a row (configuration entry) simultaneously and use the same value. If it is currently unused, the SET succeeds and the Command Responder (agent) changes the value of this object, according to an implementation-specific algorithm. If the value is in use, however, the SET fails. The Network Management Application must then re-read this variable to obtain a new usable value. An OBJECT-TYPE definition using this SYNTAX MUST specify the relevant table for which the object is providing this functionality."

These are associated with individual interfaces, logical or physical, and therefore are instantiated by ifIndex. Therefore, the interface index must have been assigned, according to the procedures applicable to that, before it can be meaningfully used. Generally, this means that the interface must exist.

The actual classification definitions are defined in diffServClfrElementTable entries belonging to each classifier. An entry in this table, pointed to by a RowPointer specifying an instance of diffServClfrStatus, is frequently used as the name for a set of classifier elements, which all use the index diffServClfrId. Per the semantics of the classifier element table, these entries constitute one or more unordered sets of tests which may be simultaneously applied to a message to classify it. The primary function of this table is to ensure that the value of diffServClfrId is unique before attempting to use it in creating a diffServClfrElementEntry. Therefore, the diffServClfrEntry must be created on the same SET as the diffServClfrElementEntry, or before the diffServClfrElementEntry is created." ::= { diffServClassifier 2 } diffServClfrEntry OBJECT-TYPE SYNTAX DiffServClfrEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "An entry in the classifier table describes a single classifier.

A classifier may use filter tables of different types together. One example of a filter table defined in this MIB is diffServMultiFieldClfrTable, for IP Multi-Field Classifiers (MFCs). Such an entry might identify anything from a single micro-flow (an identifiable sub-session packet stream directed from one sending transport to the receiving transport or transports), or aggregates of those such as the traffic from a host, traffic for an application, or traffic between two hosts using an application and a given DSCP.

Classifier elements with the same order must be unambiguous i.e. they must define non-overlapping patterns, and are considered to be applied simultaneously to the traffic stream. Classifier elements with different order may overlap in their filters: the classifier element with the highest order that matches is taken. On a given interface, there must be a complete classifier in place at all times in the ingress direction. This means one or more filters must match any possible pattern.
