1. 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].

It is the purpose of this document to define managed objects which
describe the behavior of an SNMP entity, as defined in the SNMP
architecture STD 62, [RFC3411].

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 BCP 14, RFC 2119
[RFC2119].

include the full name and version identification of
the system's hardware type, software operating-system,
and networking software."
::= { system 1 }

sysObjectID OBJECT-TYPE
SYNTAX OBJECT IDENTIFIER
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The vendor's authoritative identification of the
network management subsystem contained in the entity.
This value is allocated within the SMI enterprises
subtree (1.3.6.1.4.1) and provides an easy and
unambiguous means for determining `what kind of box' is
being managed. For example, if vendor `Flintstones,
Inc.' was assigned the subtree 1.3.6.1.4.1.424242,
it could assign the identifier 1.3.6.1.4.1.424242.1.1
to its `Fred Router'."

sysName OBJECT-TYPE
SYNTAX DisplayString (SIZE (0..255))
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"An administratively-assigned name for this managed

sysLocation OBJECT-TYPE
SYNTAX DisplayString (SIZE (0..255))

value is the zero-length string."
::= { system 6 }

sysServices OBJECT-TYPE
SYNTAX INTEGER (0..127)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"A value which indicates the set of services that this
entity may potentially offer. The value is a sum.

Presuhn, et al. Standards Track [Page 5]

RFC 3418 MIB for SNMP December 2002

This sum initially takes the value zero. Then, for
each layer, L, in the range 1 through 7, that this node
performs transactions for, 2 raised to (L - 1) is added
to the sum. For example, a node which performs only
routing functions would have a value of 4 (2^(3-1)).
In contrast, a node which is a host offering application
services would have a value of 72 (2^(4-1) + 2^(7-1)).
Note that in the context of the Internet suite of
protocols, values should be calculated accordingly:

layer functionality
1 physical (e.g., repeaters)
2 datalink/subnetwork (e.g., bridges)
3 internet (e.g., supports the IP)
4 end-to-end (e.g., supports the TCP)
7 applications (e.g., supports the SMTP)

For systems including OSI protocols, layers 5 and 6
may also be counted."

example, SNMPv1) delivered to the SNMP entity which
represented an SNMP operation that was not allowed for
the SNMP community named in the message. The precise
conditions under which this counter is incremented
(if at all) depend on how the SNMP entity implements
its access control mechanism and how its applications
interact with that access control mechanism. It is

5. Security Considerations

There are a number of management objects defined in this MIB that
have a MAX-ACCESS clause of read-write. 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.

SNMPv1 by itself is not a secure environment. 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) the objects in this MIB.

Presuhn, et al. Standards Track [Page 22]

RFC 3418 MIB for SNMP December 2002

It is recommended that the implementors consider the security
features as provided by the SNMPv3 framework. Specifically, the use
of the User-based Security Model STD 62, RFC 3414 [RFC3414] and the
View-based Access Control Model STD 62, RFC 3415 [RFC3415] is
recommended.

It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB is properly
configured to give access to the objects only to those principals
(users) that have legitimate rights to indeed GET or SET (change)
them.
