Abstract

   This memo defines managed objects for sampling and filtering
   techniques for IP packet selection.  These objects provide
   information about managed nodes supporting packet sampling, including
   packet sampling capabilities and configuration.  They also allow to
   configure packet sampling concerning the IP interface at which
   packets are sampled and the packet selections methods used for
   sampling.

Internet-Draft                  PSAMP MIB                      June 2006


1.  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.

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

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).

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.

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.

7.  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.  IANA Considerations

   This document requires no assignment to be made by IANA.
