Internet-Draft draft-fu-softwire-4rd-mib-00.txt February 2012
1. Introduction
4rd [I-D.murakami-softwire-4rd], [I-D.despres-softwire-4rd] is a
stateless mechanism for running IPv4 over IPv6-only infrastructure.
It provides an automatic tunnelling mechanism for providing IPv4
connectivity service to end users over a service provider's IPv6
network.
This document defines a portion of the Management Information Base
(MIB) for use with network management protocols in the Internet
community. This MIB module may be used for monitoring the devices in
the 4rd scenario.
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
[RFC3410].
Managed objects are accessed via a virtual information store, termed
the 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
[RFC2578], [RFC2579] and [RFC2580].
3. 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 [RFC2119].
4. Structure of the MIB Module
The 4rd MIB provides a way to configure and manage the devices in 4rd
scenario through SNMP.
4rd MIB is configurable on a per-interface basis. It depends on
several parts of the IF-MIB [RFC2863] and tunnel MIB [RFC4087].
4.1. The fourRdTunnel Subtree
The fourRdTunnel subtree describes managed objects used for managing
tunnels in the 4rd scenario. Because the tunnel MIB supports the
Fu, et al. Expires August 4, 2012 [Page 3]
Internet-Draft draft-fu-softwire-4rd-mib-00.txt February 2012
tunnel management function in 4rd, we may reuse it in 4rd MIB.
However, a 4rd BR is considered to be a collection of 4rd tunnel
endpoints which is distinguished by different mapping rules. It needs
to extend the tunnel MIB by some parameters of mapping rule ID to
distinguish the different tunnels.
4.2. The fourRdStatisticInfo Subtree
The fourRdStatisticInfo subtree provides state and statistical
information for 4rd BRs or 4rd tunnel endpoints.
4.3. The fourRdTrap Subtree
The fourRdTrap Subtree provides trap information in 4rd instance.
4.4. The fourRdConformance Subtree
The Subtree provides conformance information of MIB objects.
5. MIB modules required for IMPORTS
This MIB module IMPORTs objects from [RFC4087], [RFC2580], [RFC2578],
[RFC2863], [RFC4001], [RFC3411].

7. IANA Considerations
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
fourRd-MIB { transmission XXX }
8. Security Considerations
The 4rd MIB module can be used for configuration of certain objects,
and anything that can be configured can be incorrectly configured,
with potentially disastrous results. Because this MIB module reuses
the IP tunnel MIB, the security considerations for these MIBs are
also applicable to the 4rd MIB.
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 principles (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
