Abstract

 Reliable Server Pooling (RSerPool) is a framework to provide reliable
 server pooling.  The RSerPool framework consists of two protocols:
 ASAP (Aggregate Server Access Protocol) and ENRP (Endpoint
 Handlespace Redundancy Protocol).  This document defines an SMIv2-
 compliant (Structure of Management Information Version 2) Management
 Information Base (MIB) module providing access to managed objects in
 an RSerPool implementation.

1. Introduction

 This memo defines a Management Information Base (MIB) module that
 describes managed objects for RSerPool implementations.

2. The Reliable Server Pooling (RSerPool) Framework

 For a detailed overview of the documents that describe the current
 Reliable Server Pooling (RSerPool) framework, please refer to
 [RFC3237], [RFC5351], [RFC5352], [RFC5353], [RFC5354], [RFC5355], and
 [RFC5356].  A more informal introduction can be found at
 [RSerPoolPage] as well as in [Dre2006], [LCN2005], and [IJHIT2008].

3. Conventions

 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 [RFC2119].

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).

Dreibholz & Mulik Experimental [Page 2] RFC 5525 RSerPool MIB Module April 2009

 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].  The textual conventions are compliant to RFC 4001
 [RFC4001].

 As the figure shows, the MIB consists of three main branches:
 "rserpoolENRPServers", "rserpoolPoolElements", and
 "rserpoolPoolUsers".  The first branch, "rserpoolENRPServers", is
 used to access managed objects in the set of ENRP servers running on
 a given host.  While it is assumed that it does not make much sense
 to run multiple ENRP servers for the same operation scope on one
 host, running multiple ENRP servers for different operation scopes is
 very likely when the ENRP server processes run on routers.
 Therefore, the MIB has to be able to manage multiple ENRP servers on
 the same host.
 "rserpoolPoolElements" is used to access managed objects in the set
 of pool elements that are running on a given host.
 The third branch, "rserpoolPoolUsers", is used to access managed
 objects in the set of pool users that are running on a given host.
 Note: "rserpoolENRPServers" is filled on hosts running ENRP server
 instances, "rserpoolPoolElements" is filled on hosts running pool
 element instances, and "rserpoolPoolUsers" is filled on hosts running
 pool user instances.  Of course, multiple different components may
 run on the same host, which leads to filling of multiple different
 branches.
 In fact, the structure of the three branches is very similar.
 Because the other two branches are so similar, we describe only the
 first branch in detail, and provide a summary description of the
 second and third branch.  We now proceed with a description of the
 branches.

Dreibholz & Mulik Experimental [Page 9] RFC 5525 RSerPool MIB Module April 2009

5.1. Access to Managed Objects on ENRP Servers

 The first branch describes managed objects at a set of ENRP servers.
 Any given ENRP server of this set will, at a certain moment in time,
 have registration information for a set of active pools.  Each of
 these pools in turn may have a list of pool elements that are
 registered under that pool.  To allow this information to be
 retrieved via SNMP, the ERNP server branch of the RSerPool MIB uses
 the table-in-table technique described in [SNMPMIBS].
 Specifically, the ENRP servers branch creates four levels of nesting,
 as indicated in the following diagram:
 Nesting of the ENRP Server Branch
 Nesting Structure:
  Level 1: rserpoolENRPTable
  Level 2:    rserpoolENRPPoolTable
  Level 3:       rserpoolENRPPoolElementTable
  Level 4:          rserpoolENRPASAPAddrTable
                    rserpoolENRPUserAddrTable
  Level 2:    rserpoolENRPENRPAddrTable
  Level 2:    rserpoolENRPPeerTable
  Level 3:       rserpoolENRPPeerAddrTable

5.2. Access to Managed Objects on Pool Elements

 The construction of the Pool Elements branch is very similar to the
 pool elements table of the ENRP servers branch.  But instead of
 grouping the pool elements into pools (which does not make sense
 here), the pool elements table is the top of the hierarchy, and each
 pool element entry specifies its operation scope and pool handle.
 That is, the nesting structure is as follows:
 Nesting of the Pool Elements Branch
  Level 1:    rserpoolPETable
  Level 2:       rserpoolPEASAPAddrTable
                 rserpoolPEUserAddrTable

Dreibholz & Mulik Experimental [Page 10] RFC 5525 RSerPool MIB Module April 2009

5.3. Access to Managed Objects on Pool Users

 For the Pool Users branch, it is only necessary to list the pool user
 instances, including their operation scope and pool handle.

5.4. Persistency Behavior

 Upon changes of writable objects, an implementation SHOULD store the
 new values in a persistent manner if it has the capability to do
 this.  An implementation SHOULD use these stored values upon reset or
 reinitialization.

7. Operational Considerations

 The RSerPool MIB is an Experimental track MIB module, since the
 RSerPool documents are Experimental RFCs.

8. 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.  These are the tables and objects and their
 sensitivity/vulnerability:
    rserpoolENRPDescription (textual description change)
    rserpoolPEPoolHandle (pool handle of pool element change, similar
    to ASAP)
    rserpoolPEDescription (textual description change)
    rserpoolPEPolicyID (pool element ID change, similar to ASAP)
    rserpoolPEPolicyDescription (textual description change)
    rserpoolPEPolicyWeight (policy weight change, similar to ASAP)
    rserpoolPEPolicyLoadDeg (policy load degradation change, similar
    to ASAP)
    rserpoolPERegistrationLife (registration lifetime change, similar
    to ASAP)
    rserpoolPUPoolHandle (pool handle of accessed pool change, similar
    to ASAP)
    rserpoolPUDescription (textual description change)
 The security implications of changing these items are similar to
 changes via ASAP; the corresponding security implications are
 described in the threats document [RFC5355].  Modifying the textual
 descriptions of components may result in wrong administrator
 decisions upon malicious information.

Dreibholz & Mulik Experimental [Page 42] RFC 5525 RSerPool MIB Module April 2009

 Some of the readable objects in this MIB module (i.e., objects with a
 MAX-ACCESS other than not-accessible) may be considered sensitive or
 vulnerable in some network environments.  It is thus important to
 control even GET and/or NOTIFY access to these objects and possibly
 to even encrypt the values of these objects when sending them over
 the network via SNMP.  Read access reveals the same information which
 is also available by ASAP and ENRP access.  The security implications
 of these two protocols are explained in detail by the threats
 document [RFC5355].
 SNMP versions prior to SNMPv3 did not include adequate security.
 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 module.
 It is RECOMMENDED that implementers consider the security features as
 provided by the SNMPv3 framework (see [RFC3410], section 8),
 including full support for the SNMPv3 cryptographic mechanisms (for
 authentication and privacy).
 Further, deployment of SNMP versions prior to SNMPv3 is NOT
 RECOMMENDED.  Instead, it is RECOMMENDED to deploy SNMPv3 and to
 enable cryptographic security.  It is then a customer/operator
 responsibility to ensure that the SNMP entity giving access to an
 instance of this MIB module 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.

9. IANA Considerations

 The MIB module in this document uses the following IANA-assigned
 OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
