Open Issues/TODOs o Align MIB with other drafts, esp. the Sampling Techniques one. o Is the selecting all method mandatory for all implementations? o Describe row status objects to writable tables. o Elaborate conformance statements. o Add option template id to each parameter set for exporting option data. o Check data type for "microseconds", protocol type, port, template id and maybe some others. o Need to achieve a common layout and naming on the different MIB parts. o Elaborate security considerations, particularly concerning SET operations. 2. Introduction 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 RFC 2119 [RFC2119]. This document is a product of the Packet Sampling (PSAMP) working group. Its purpose is to define standards-based MIB modules for monitoring and configuring PSAMP devices performing packet selection by sampling, filtering and hashing. It is assumed that packet sampling is performed according to the framework defined in [I-D.ietf-psamp-framework]. Packet selection methods considered in the MIB module are specified in [I-D.ietf- psamp-sample-tech]. Configuration of the export of packet samples to a collector is modeled according to [I-D.ietf-psamp-protocol]. The exporter uses the IPFIX protocol as specified in [I-D.ietf-ipfix- protocol]. The MIB presented here is a module of the IPFIX MIB [I-D.dietz-ipfix- mib]. It starts at an Object ID in the IPFIX MIB and imports the textual conventions defined there. 3. PSAMP Documents Overview PSAMP Framework: [I-D.ietf-psamp-framework] "A Framework for Packet Selection and Reporting" The document describes the PSAMP framework for network elements to select subsets of packets by statistical and other methods, and to export a stream of reports on the selected packets to a collector. Definitions of terminology and the use of the terms "must", "should" and "may" in this document are informational only. Dietz & Claise draft-ietf-psamp-mib-06.txt [Page 3] Internet-Draft PSAMP MIB June 2006 PSAMP Sampling Techniques: [I-D.ietf-psamp-sample-tech] "Sampling and Filtering Techniques for IP Packet Selection", describes the set of packet selection techniques supported by PSAMP. PSAMP MIB: "Definitions of Managed Objects for Packet Sampling" (this document) describes the PSAMP Management Information Base. PSAMP Protocol: [I-D.ietf-psamp-protocol] "Packet Sampling (PSAMP) Protocol Specifications" specifies the export of packet information from a PSAMP Exporting Process to a PSAMP Colleting Process. PSAMP Information Model: [I-D.ietf-psamp-info] "Information Model for Packet Sampling Exports" defines an information and data model for PSAMP. Section 5 describes the structure of the PSAMP MIB module and section 6 contains the formal definition. Security issues are finally discussed in section 7. 4. 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]. 5. Structure of the PSAMP MIB module The PSAMP MIB module is structure according to the sample techniques document [I-D.ietf-psamp-sample-tech]. The main structure follows the building blocks of the PSAMP framework [I-D.ietf-psamp- framework], describing sampling/filtering at an observation point then exporting the collected information to one or more collectors. The objects needed for exporting the information and describing and configuring the selection methods used in the metering process are Dietz & Claise draft-ietf-psamp-mib-06.txt [Page 4] Internet-Draft PSAMP MIB June 2006 already defined in the IPFIX MIB Exporter Module [I-D.dietz-ipfix- mib]. The PSAMP MIB Module contains parameter sets for the sampling and filtering methods described in [I-D.ietf-psamp-sample-tech]. The sampling and filtering methods and their parameter sets are controlled by three groups of objects: The sampling group, the filtering group and the hash functions group. The sampling group and the filtering group define the parameters for the sampling and filtering methods. The hash functions group defines the available hash functions for hash based filtering. Finally we have the statistics group that represent all objects collecting the optional statistical values like packets observed by a hash function or reports sent to a collector. In the next sections we will briefly describe every object group and its usage. 5.1. The Sampling Group The first group of objects contains information about sampling methods. Each sampling method is covered by an individual sub-tree of this group. The following objects are defined for each method except the first: a sub-group of objects indicating specific capabilities and limits of the method that may be empty if no capabilities or limits are available, and a sub-group specifying sets of parameters in a table. Each row in the parameter set table uniquely specifies all parameters of a packet sampling instance of the method. Also all parameters sets contain a row status. Methods and parameters of methods are specified in [I-D.ietf-psamp- sample-tech]. The PSAMP MIB document specifies all methods defined in the sample tech document. If some object need further specification then OBJECT IDENTIFIERS are used as pointers to functions or parameters that are out of the scope of this document. They can be implemented in a vendor specific way or may be documented in another document or a later version of this document. An implementer may specify e.g., one or more functions used for non- uniform probabilistic sampling. The seven methods specified in this document are selecting all, systematic count-based sampling, systematic time-based sampling, random n-out-of-N sampling, uniform probabilistic sampling, non-uniform probabilistic sampling and flow state sampling. 5.1.1. Selecting All Packets This trivial packet selection method is alway available. If it is applied, all packets will be selected. Dietz & Claise draft-ietf-psamp-mib-06.txt [Page 5] Internet-Draft PSAMP MIB June 2006 5.1.2. Systematic Count-based Sampling The systematic count-based sampling method has two capability objects: The psampSampCountBasedMaxInterval object indicates the maximum sampling interval in packets supported by the implementation, whereas psampSampCountBasedMaxSpacing indicates the maximum spacing in packets supported by the implementation. Finally the psampSampCountBasedParamSetTable contains two parameters: the sampling interval length and the spacing specified in numbers of packets. 5.1.3. Systematic Time-based Sampling The systematic time-based sampling method has two capability objects: psampSampTimeBasedMaxInterval indicates the maximum sampling interval in microseconds supported by the implementation, whereas psampSampTimeBasedMaxSpacing indicates the maximum spacing in microseconds supported by the implementation. Finally the psampSampTimeBasedParamSetTable contains two parameters: the sampling interval length and the spacing specified in microseconds. 5.1.4. Random n-out-of-N Sampling The random n-out-of-N sampling method has two capability objects: psampSampRandOutOfNMaxPopulation specifying the maximum population N, and psampSampRandOutOfNMaxSample the maximum size of n supported by the implementation. The random n-out-of-N sampling method has also two parameter objects in the psampSampRandOutOfNParamSetTable. The first one is psampSampRandOutOfNPopulation and gives the number of elements N in the parent population. The second psampSampRandOutOfNSample gives the number of elements n taken from the parent population N. With these two parameters you sample n packets out of N. 5.1.5. Uniform Probabilistic Sampling The uniform probabilistic sampling method has no capabilities and only one parameter in the psampSampUniProbParamSetTable, the psampSampUniProbProbability. This object gives the probability that a packet is sampled. The probability is equal for every packet. The given value must be divided by 4294967295 (=2^32-1), so a value of 0 means no packet is sampled (probability is 0) and a value of 4294967295 means every packet is sampled (probability is 1). Dietz & Claise draft-ietf-psamp-mib-06.txt [Page 6] Internet-Draft PSAMP MIB June 2006 5.1.6. Non-Uniform Probabilistic Sampling The non-uniform probabilistic sampling method has also no capabilities defined. The psampSampNonUniProbParamSetTable contains two parameters, the psampSampNonUniProbFunction and the psampSampNonUniProbFuncParam. Those two objects point to the function that computes the probability that a packet is sampled and the parameters used for that function. The definition of the function and its parameters is implementation dependent and beyond the scope of this document. 5.1.7. Flow State Sampling The capabilities and parameter set of the flow state sampling method are equal to those of the non-uniform probabilistic sampling method. There are no capabilities defined and the psampSampFlowStateParamSetTable hold two parameters pointing to the flow state function and the parameters used by the flow state function (psampSampFlowStateFunction and psampSampFlowStateFuncParam). Again the function and its parameters are implementation dependent and beyond the scope of this document. 5.2. The Filtering Methods Group The second group contains information about the filtering methods. This group is build up similarly to the sampling methods group. It currently contains three filtering methods, the match filtering, the hash filtering and the router state filtering. 5.2.1. Match Filtering The match filtering method has no capabilities defined and contains four parameters in the psampFilterMatchParamSetTable: The psampFilterMatchFieldId contain the PSAMP or IPFIX field id defined in the information model as reference what to match. The psampFilterMatchStartValue and psampFilterMatchStopValue contain the start and stop value to match the content against. In this way you can match e.g., a range x-z of transport protocol ports by specifying the field id that represents the transport protocol port and giving x as start value and y as stop value. If a single value should be matched than start and stop value must be equal. A mask psampFilterMatchMask can be applied if it is applicable for the field id. The encoding of the values is dependent on the field id and has to be done according to the PSAMP protocol document. 5.2.2. Hash Filtering Capabilities are not specified for the hash filtering method. But Dietz & Claise draft-ietf-psamp-mib-06.txt [Page 7] Internet-Draft PSAMP MIB June 2006 according to the sample tech document [I-D.ietf-psamp-sample-tech] ten parameters are defined in the psampFilterHashParamSetTable. The psampFilterHashAddrType specifies the address type to hash - either IPv4 or IPv6. Then psampFilterHashHeaderBits specifies a bit mask applied to the packet header selecting the bits to hash from the packet header. Then psampFilterHashPayloadBytes gives the number of payload bytes that should be included in the hashing. The final bits that are selected from the payload bytes are masked with the psampFilterHashPayloadBits. The above parameters specified what gets feed into the hash function. The following parameters specify the hash function itself. The psampFilterHashFunction points to a hash function and psampFilterHashFuncParam point to a function specific parameter set for the hashing function. The number of input and output bits for the hash function is specified with psampFilterHashInputBits and psampFilterHashOutputBits. Finally the output may be masked with the psampFilterHashOutputMask. The results gained by applying all those parameters are then compared with the psampFilterHashSelection. The psampFilterHashSelection contains the hash value ranges or single hash values that get selected. The psampFilterHashSelection is a human readable string containing only the ASCII characters 0-9, a-f, comma(,) and dash(-). The ASCII string is defined as follows: selections := selection | selections,selection selection := range | value range := value-value value := 0x[0-9,a-f]* | [1-9][0-9]* The two hash functions given in the sample tech document can be referenced within this parameter set table and are also contained in this PSAMP MIB document. 5.2.3. Router State Filtering The router state filtering does also not specify any capabilities. The parameter table psampFilterRStateParamSetTable contains six parameters to specify the router state to filter against. The first object psampFilterRStateFunction defines one of nine functions that may be used as router state. other: an other router state function that is not defined here. Then psampFilterRStateVendorFunc points to the implementation specific function that is used. Dietz & Claise draft-ietf-psamp-mib-06.txt [Page 8] Internet-Draft PSAMP MIB June 2006 ingressIf: packets that enter the probe at the interface specified by psampFilterRStateIfIndex are matched. egressIf: packets that leave the probe at the interface specified by psampFilterRStateIfIndex are matched. aclViolation: packets that violate the access control list are matched. rpfFailure: packets for that the reverse path forwarding fails are matched. noResources: packets for that not enough resources are allocated will be matched. noRoute: packets that could not be routed further are matched. originAS: packets that originate in an autonomous system specified by the range of psampFilterRStateStartAS and psampFilterRStateStopAS are matched. destAS: packets whose destination is in an autonomous system specified by the range of psampFilterRStateStartAS and psampFilterRStateStopAS are matched. The parameter psampFilterRStateIfIndex defaults to 0 if not used. The parameters psampFilterRStateStartAS and psampFilterRStateStopAS default to 0 if they are not used. If a single autonomous system number should be matched psampFilterRStateStopAS remains 0. 5.3. The Hash Functions Group The hash function group specifies the two hash functions defined in the sample tech document [I-D.ietf-psamp-sample-tech]. The hash functions are defined here so that they can be referenced by the hash filter above. The design of the hash function part of the MIB SHOULD be taken as a guideline for vendor specific hash function definitions. The two hash functions IPSX and Bob have both an empty parameter set table since they both take now additional parameters than those specified in the hash filter method. Other hash functions of course could specify additional parameters. Dietz & Claise draft-ietf-psamp-mib-06.txt [Page 9] Internet-Draft PSAMP MIB June 2006 6.

Security Considerations There are a number of management objects defined in this MIB module with 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. 8.
