RMON2-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.

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 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." SYNTAX TimeStamp TimeFilter ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "To be used for the index to a table. Allows an application to download only those rows changed since a particular time. A row is considered changed if the value of any object in the row changes or if the row is created or deleted. When sysUpTime is equal to zero, this table shall be empty. One entry exists for each past value of sysUpTime, except that the whole table is purged should sysUpTime wrap. As this basic row is updated new conceptual rows are created (which still share the now updated object values with all other instances). The number of instances which are created is determined by the value of sysUpTime at which the basic row was last updated. One instance will exist for each value of sysUpTime at the last update time for the row. A new timeMark instance is created for each new sysUpTime value. Each new conceptual row will be associated with the timeMark instance which was created at the value of sysUpTime with which the conceptual row is to be associated. By definition all conceptual rows were updated at or after time zero and so at least one conceptual row (associated with timeMark.0) must exist for each underlying (basic) row. See the appendix for further discussion of this variable. Consider the following fooTable: fooTable ... INDEX { fooTimeMark, fooIndex } FooEntry { fooTimeMark TimeFilter fooIndex INTEGER, fooCounts Counter } Should there be two basic rows in this table (fooIndex == 1, fooIndex == 2) and row 1 was updated most recently at time 6, while row 2 was updated most recently at time 8, and both rows had been updated on several earlier occasions such that the current values were 5 and 9 respectively then the following fooCounts instances would exist. fooCounts.0.1 5 fooCounts.0.2 9 fooCounts.1.1 5 fooCounts.1.2 9 fooCounts.2.1 5 fooCounts.2.2 9 fooCounts.3.1 5 fooCounts.3.2 9 fooCounts.4.1 5 fooCounts.4.2 9 fooCounts.5.1 5 fooCounts.5.2 9 fooCounts.6.1 5 fooCounts.6.2 9 fooCounts.7.2 9 -- note that row 1 doesn't exist for fooCounts.8.2 9 -- times 7 and 8" SYNTAX TimeTicks DataSource ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "Identifies the source of the data that the associated function is configured to analyze.

There is one entry in this table for each such protocol. These protocols represent different network layer, transport layer, and higher-layer protocols. The agent should boot up with this table preconfigured with those protocols that it knows about and wishes to monitor. Implementations are strongly encouraged to support protocols higher than the network layer (at least for the protocol distribution group), even for implementations that don't support the application layer groups." ::= { protocolDir 2 } protocolDirEntry OBJECT-TYPE SYNTAX ProtocolDirEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "A conceptual row in the protocolDirTable. An example of the indexing of this entry is protocolDirLocalIndex.8.0.0.0.1.0.0.8.0.2.0.0, which is the encoding of a length of 8, followed by 8 subids encoding the protocolDirID of 1.2048, followed by a length of 2 and the 2 subids encoding zero-valued parameters."

Standard identifiers will be defined in a manner such that they can often be used as specifications for new protocols - i.e. a tree-structured assignment mechanism that matches the protocol encapsulation `tree' and which has algorithmic assignment mechanisms for certain subtrees. See RFC XXX for more details. Despite the algorithmic mechanism, the probe will only place entries in here for those protocols it chooses to collect. In other words, it need not populate this table with all of the possible ethernet protocol types, nor need it create them on the fly when it sees them. Whether or not it does these things is a matter of product definition (cost/benefit, usability), and is up to the designer of the product. If an entry is written to this table with a protocolDirID that the agent doesn't understand, either directly or algorithmically, the SET request will be rejected with an inconsistentName or badValue (for SNMPv1) error." ::= { protocolDirEntry 1 } protocolDirParameters OBJECT-TYPE SYNTAX OCTET STRING MAX-ACCESS not-accessible STATUS current DESCRIPTION "A set of parameters for the associated protocolDirID.

There will be one octet in this string for each sub-identifier in the protocolDirID, and the parameters will appear here in the same order as the associated sub-identifiers appear in the protocolDirID. Every node in the protocolDirID tree has a different, optional set of parameters defined (that is, the definition of parameters for a node is optional). The proper parameter value for each node is included in this string. Note that the inclusion of a parameter value in this string for each node is not optional - what is optional is that a node may have no parameters defined, in which case the parameter field for that node will be zero." ::= { protocolDirEntry 2 } protocolDirLocalIndex OBJECT-TYPE SYNTAX Integer32 (1..2147483647) MAX-ACCESS read-only STATUS current DESCRIPTION "The locally arbitrary, but unique identifier associated with this protocolDir entry. The value for each supported protocol must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization, except that if a protocol is deleted and re-created, it must be re-created with a new value that has not been used since the last re-initialization.

This object may not be modified if the associated protocolDirStatus object is equal to active(1)." ::= { protocolDirEntry 4 } protocolDirType OBJECT-TYPE SYNTAX BITS { extensible(0), addressRecognitionCapable(1) } MAX-ACCESS read-only STATUS current DESCRIPTION "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." ::= { protocolDirEntry 5 } protocolDirAddressMapConfig OBJECT-TYPE SYNTAX INTEGER { notSupported(1), supportedOff(2), supportedOn(3) } MAX-ACCESS read-create STATUS current DESCRIPTION "This object describes and configures the probe's support for address mapping for this protocol. When the probe creates entries in this table for all protocols that it understands, it will set the entry to notSupported(1) if it doesn't have the capability to perform address mapping for the protocol or if this protocol is not a network-layer protocol. When an entry is created in this table by a management operation as part of the limited extensibility feature, the probe must set this value to notSupported(1), because limited extensibility of the protocolDirTable does not extend to interpreting addresses of the extended protocols. If the value of this object is notSupported(1), the probe will not perform address mapping for this protocol and shall not allow this object to be changed to any other value. If the value of this object is supportedOn(3), the probe supports address mapping for this protocol and is configured to perform address mapping for this protocol for all addressMappingControlEntries and all interfaces. If the value of this object is supportedOff(2), the probe supports address mapping for this protocol but is configured to not perform address mapping for this protocol for any addressMappingControlEntries and all interfaces. Whenever this value changes from supportedOn(3) to supportedOff(2), the probe shall delete all related entries in the addressMappingTable." ::= { protocolDirEntry 6 } protocolDirHostConfig OBJECT-TYPE SYNTAX INTEGER { notSupported(1), supportedOff(2), supportedOn(3) } MAX-ACCESS read-create STATUS current DESCRIPTION "This object describes and configures the probe's support for the network layer and application layer host tables for this protocol. When the probe creates entries in this table for all protocols that it understands, it will set the entry to notSupported(1) if it doesn't have the capability to track the nlHostTable for this protocol or if the alHostTable is implemented but doesn't have the capability to track this protocol. Note that if the alHostTable is implemented, the probe may only support a protocol if it is supported in both the nlHostTable and the alHostTable. If the associated protocolDirType object has the addressRecognitionCapable bit set, then this is a network layer protocol for which the probe recognizes addresses, and thus the probe will populate the nlHostTable and alHostTable with addresses it discovers for this protocol. If the value of this object is notSupported(1), the probe will not track the nlHostTable or alHostTable for this protocol and shall not allow this object to be changed to any other value. If the value of this object is supportedOn(3), the probe supports tracking of the nlHostTable and alHostTable for this protocol and is configured to track both tables for this protocol for all control entries and all interfaces. If the value of this object is supportedOff(2), the probe supports tracking of the nlHostTable and alHostTable for this protocol but is configured to not track these tables for any control entries or interfaces. Whenever this value changes from supportedOn(3) to supportedOff(2), the probe shall delete all related entries in the nlHostTable and alHostTable. Note that since each alHostEntry references 2 protocol directory entries, one for the network address and one for the type of the highest protocol recognized, that an entry will only be created in that table if this value is supportedOn(3) for both protocols." ::= { protocolDirEntry 7 } protocolDirMatrixConfig OBJECT-TYPE SYNTAX INTEGER { notSupported(1), supportedOff(2), supportedOn(3) } MAX-ACCESS read-create STATUS current DESCRIPTION "This object describes and configures the probe's support for the network layer and application layer matrix tables for this protocol. When the probe creates entries in this table for all protocols that it understands, it will set the entry to notSupported(1) if it doesn't have the capability to track the nlMatrixTables for this protocol or if the alMatrixTables are implemented but don't have the capability to track this protocol. Note that if the alMatrix tables are implemented, the probe may only support a protocol if it is supported in the the both of the nlMatrixTables and both of the alMatrixTables. If the associated protocolDirType object has the addressRecognitionCapable bit set, then this is a network layer protocol for which the probe recognizes addresses, and thus the probe will populate both of the nlMatrixTables and both of the alMatrixTables with addresses it discovers for this protocol. If the value of this object is notSupported(1), the probe will not track either of the nlMatrixTables or the alMatrixTables for this protocol and shall not allow this object to be changed to any other value.
