Internet Draft Service Location Protocol MIB 27 February 2003
1. Introduction
The SLP MIB supports minimal passive monitoring of SLPv2 agents for
network management purposes. The SLP MIB also supports (optional)
passive monitoring of configured or discovered SLPv2 DA/SA network
addresses and SLPv2 DA/SA attributes.
This document is structured as follows:
- Section 2 briefly describes the SNMP network management framework.
- Section 3 enumerates design requirements for the SLP MIB.
- Section 4 provides an overview of the SLP MIB, including
conformance terminology and SLP-specific terminology.
- Section 5 specifies the SLP MIB in SMIv2 [RFC2578], including the
conformance requirements for SNMP Command Responders that claim
conformance to this document.
- Sections 6, 7, 8, and 9 specify IANA, intellectual property,
internationalization, and security considerations.
- Sections 10, 11, 12, 13, and 14 list acknowledgements, normative
references, informative references, authors' addresses, and full
IETF copyright statement.
2. 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].

Internet Draft Service Location Protocol MIB 27 February 2003
3. Design Requirements for SLP MIB
The SLP MIB design requirements listed below are _not_ conformance
requirements on _implementations_ of the SLP MIB. Therefore the
words must, should, and may are used below in lowercase (informative
per [RFC2119] conventions).
(1) The SLP MIB must provide an SNMP interface to monitor SLPv2
[RFC2608] directory agents (DAs), service agents (SAs), and user
agents (UAs).
(2) The SLP MIB must be organized so that access can be controlled
effectively by using the User-based Security Model [RFC2574] and
the View-based Access Control Model [RFC2575] from the SNMPv3
framework.
(3) The SLP MIB must not compromise native security in SLPv2
[RFC2608] by exposing private keys or other confidential
information via SNMP.
(4) The SLP MIB must define a core set of mandatory object groups
that support minimal passive monitoring requirements.
(5) The SLP MIB must use UTF-8 [2279] for all human-readable text
strings per [RFC2277] for internationalization support.
4. Overview of SLP MIB
The SLP MIB can be used to monitor SLPv2 [RFC2608] directory agents
(DAs), service agents (SAs), and user agents (UAs). The SLP MIB
makes no assumptions about the particular system topology of the
managed SLP agents (for example, they may be distributed across
several rack-mounted processors in a router).
4.1. Conformance Terminology
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].
Bakke, McDonald Expires 27 August 2003 [Page 4]
Internet Draft Service Location Protocol MIB 27 February 2003
4.2. SLP Terminology
The SLP MIB uses the following definitions from SLPv2 [RFC2608]:
- "User Agent (UA)"
A process working on the user's behalf to establish contact with
some service. The UA retrieves service information from the
Service Agents or Directory Agents.
- "Service Agent (SA)"
A process working on the behalf of one or more services to
advertise the services.
- "Directory Agent (DA)"
A process which collects service advertisements. There can only be
one DA present per given host.
- "Scope"
A set of services, typically making up a logical administrative
group.
4.3. Abstract Model of SLP MIB
The Agent group is the principal object group in the abstract model
defined in the SLP MIB.
The Scope, Address, and Attribute tables (all subordinate to
"slpAgentTable") each use a high-order index of "slpAgentIndex" for
linkage to the "slpAgentTable".

|
| (Optional)
| 0..* |===========|
|.............| Attribute | (One row per DA/SA attr)
|===========|
INDEX { slpAgentIndex,
slpAttributeIndex }
4.4. Relationship to SNMP Framework MIB (RFC 3411)
The SLP MIB defines all text strings with a syntax of
'SnmpAdminString' [RFC3411] which supports human-readable information
in UTF-8 [RFC2279].
4.5. Relationship to Host Resources MIB (RFC 2790)
The SLP MIB supports specification of the SLP agent software for each
managed SLP agent via a pointer to the 'hrSWInstalledTable' in the
Host Resources MIB [RFC2790] in the following object:
- "slpAgentSWInstalledIndexOrZero" - a value for "hrSWInstalledIndex"
in the Host Resources MIB for this SLP agent's software

6. IANA Considerations
IANA should assign a base arc in the 'mgmt' (standards track) OID
tree for the 'slpMIB' MODULE-IDENTITY defined in the SLP MIB.
The following definitions in the SLP MIB depend on IANA
registrations:
- "slpAgentMessageTypesSupported" contains an array of the binary
values assigned by SLPv2 [RFC2608] or assigned by IANA for the
Function-ID in SLPv2 messages.
- "slpAgentExtensionsSupported" contains an array of the binary
values assigned by SLPv2 [RFC2608] or assigned by IANA for the
Extension ID in SLPv2 messages.
There are no other IANA considerations associated with the SLP MIB.
7. Intellectual Property
The IETF takes no position regarding the validity or scope of any
intellectual property or other rights that might be claimed to
pertain to the implementation or use of the technology described in
this document or the extent to which any license under such rights
might or might not be available; neither does it represent that it
has made any effort to identify any such rights. Information on the
IETF's procedures with respect to rights in standards-track and
standards-related documentation can be found in RFC 2028. Copies of
claims of rights made available for publication and any assurances of
licenses to be made available, or the result of an attempt made to
obtain a general license or permission for the use of such
proprietary rights by implementors or users of this specification can
be obtained from the IETF Secretariat.
The IETF invites any interested party to bring to its attention any
copyrights, patents or patent applications, or other proprietary
rights which may cover technology that may be required to practice
this standard. Please address the information to the IETF Executive
Director.
8. Internationalization Considerations
The SLP MIB defines all text strings with a syntax of
'SnmpAdminString' [RFC3411] which supports human-readable information
in UTF-8 [RFC2279]. The SLP MIB is therefore in full conformance
Bakke, McDonald Expires 27 August 2003 [Page 19]
Internet Draft Service Location Protocol MIB 27 February 2003
with the best practices in "IETF Policy on Character Sets and
Languages" [RFC2277].
9. Security Considerations
There are no management objects defined in this MIB module that have
a MAX-ACCESS clause of read-write and/or read-create. So, if this
MIB module is implemented correctly, then there is no risk that an
intruder can alter or create any management objects of this MIB
module via direct SNMP SET operations.
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. These are the tables and objects and their
sensitivity/vulnerability:
slpAgentTable:
slpAgentSWInstalledIndexOrZero - possible configuration data loss
slpAgentName - possible configuration data loss
slpAgentType - possible configuration data loss
slpAgentIsBroadcastOnly - possible configuration data loss
slpAgentActiveDADiscovery - possible configuration data loss
slpAgentPassiveDADiscovery - possible configuration data loss
slpAgentMessageTypesSupported - possible configuration data loss
slpAgentExtensionsSupported - possible configuration data loss
slpScopeTable:
slpScopeSource - possible configuration data loss
slpScopeValue - possible configuration data loss
slpAddressTable:
slpAddressAgentType - possible configuration data loss
slpAddressSource - possible configuration data loss
slpAddressOrName - possible configuration data loss
slpAttributeTable:
slpAttributeName - possible configuration data loss
slpAttributeType - possible configuration data loss
slpAttributeValue - possible configuration data loss
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.
Bakke, McDonald Expires 27 August 2003 [Page 20]
Internet Draft Service Location Protocol MIB 27 February 2003
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.
