有关描述当前互联网标准管理框架的文件的详细概述,请参阅RFC 3410[RFC3410]第7节。

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].

托管对象通过虚拟信息存储(称为管理信息库或MIB)进行访问。MIB对象通常通过简单网络管理协议(SNMP)进行访问。MIB中的对象是使用管理信息结构(SMI)中定义的机制定义的。本备忘录规定了符合SMIv2的MIB模块,如STD 58、RFC 2578[RFC2578]、STD 58、RFC 2579[RFC2579]和STD 58、RFC 2580[RFC2580]所述。

2. Overview
2. 概述

This memo defines an SMIv2 MIB module for managing the Rapid Spanning Tree (RSTP) capability defined by the IEEE P802.1t [802.1t] and P802.1w [802.1w] amendments to IEEE Std 802.1D-1998 [802.1D-1998] for bridging between Local Area Network (LAN) segments. The objects in this MIB are defined to apply both to transparent bridging and to bridges connected by subnetworks other than LAN segments.

本备忘录定义了一个SMIv2 MIB模块,用于管理由IEEE标准802.1D-1998[802.1D-1998]的IEEE P802.1t[802.1t]和P802.1w[802.1w]修正案定义的快速生成树(RSTP)能力,用于局域网(LAN)网段之间的桥接。此MIB中的对象定义为既适用于透明桥接,也适用于由除LAN段以外的子网连接的桥接。

There are concerns that there may be changes made in the 802.1D-2004 edition that would lead to non-backward-compatible SMI changes for 802.1t and 802.1w managed objects in the MIB modules. The Bridge MIB working group decided to 'freeze' the technical content of the MIB modules at a level that is compatible with the 802.1t and 802.1w

有人担心,802.1D-2004版中的更改可能会导致MIB模块中802.1t和802.1w受管对象的SMI更改不向后兼容。桥接MIB工作组决定“冻结”MIB模块的技术内容,使其与802.1t和802.1w兼容

4. Relation to the BRIDGE-MIB
4. 与BRIDGE-MIB的关系

The objects in the RSTP-MIB supplement those defined in the Bridge MIB [RFC4188].

RSTP-MIB中的对象补充了桥接MIB[RFC4188]中定义的对象。

The Original BRIDGE-MIB [RFC1493] has been updated in an SMIv2- compliant version [RFC4188]. Conformance statements have been added and some description and reference clauses have been updated. The interpretations of some objects were changed to accommodate IEEE 802.1t and 802.1w amendments.

原来的BRIDGE-MIB[RFC1493]已更新为符合SMIv2的版本[RFC4188]。添加了一致性声明,并更新了一些说明和参考条款。对某些对象的解释进行了更改,以适应IEEE 802.1t和802.1w修正案。

The object dot1dStpPortPathCost32 was added to support IEEE 802.1t, and the permissible values of dot1dStpPriority and dot1dStpPortPriority have been clarified for bridges supporting IEEE 802.1t or IEEE 802.1w. The interpretation of dot1dStpTimeSinceTopologyChange has been clarified for bridges supporting the RSTP.

添加了对象Dot1DSTPortPathCost32以支持IEEE 802.1t,并澄清了支持IEEE 802.1t或IEEE 802.1w的网桥的Dot1DSTPortPriority和Dot1DSTPortPriority的允许值。对于支持RSTP的桥梁,dot1dStpTimeSinceTopologyChange的解释已得到澄清。

8. Security Considerations
8. 安全考虑

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:

此MIB模块中定义了许多管理对象,其MAX-ACCESS子句为read-write和/或read-create。在某些网络环境中,此类对象可能被视为敏感或易受攻击。在没有适当保护的非安全环境中支持SET操作可能会对网络操作产生负面影响。以下是表和对象及其敏感度/漏洞:

Writable objects that could be misused to cause network delays and spanning tree instabilities include dot1dStpVersion, dot1dStpTxHoldCount, dot1dStpPortProtocolMigration, dot1dStpPortAdminEdgePort, and dot1dStpPortAdminPathCost.

可能被误用以导致网络延迟和生成树不稳定的可写对象包括dot1dStpVersion、dot1dStpTxHoldCount、dot1dstportprotocolmigration、dot1dstportadminedgeport和dot1dstportadminpathcost。

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:

在某些网络环境中,此MIB模块中的某些可读对象(即具有MAX-ACCESS而非not ACCESS的对象)可能被视为敏感或易受攻击。因此,在通过SNMP通过网络发送这些对象时,控制甚至获取和/或通知对这些对象的访问,甚至可能加密这些对象的值,这一点非常重要。以下是表和对象及其敏感度/漏洞:

dot1dStpVersion could be read by an attacker to identify environments containing applications or protocols that are potentially sensitive to RSTP mode.

攻击者可以读取dot1dStpVersion以识别包含对RSTP模式可能敏感的应用程序或协议的环境。

dot1dStpPortAdminPointToPoint could be used to mislead an access control protocol, such as 802.1x, to believe that only one other system is attached to a LAN segment and to enable network access based on that assumption. This situation could permit potential man-in-the-middle attacks.

Dot1DSTPortAdminPointPointPointPoint可用于误导访问控制协议(如802.1x),以为只有一个其他系统连接到LAN网段,并基于该假设启用网络访问。这种情况可能允许潜在的中间人攻击。

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.

SNMPv3之前的SNMP版本未包含足够的安全性。即使网络本身是安全的(例如通过使用IPsec),即使如此,也无法控制安全网络上的谁可以访问和获取/设置(读取/更改/创建/删除)此MIB模块中的对象。

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).

建议实施者考虑SNMPv3框架所提供的安全特性(参见[RCFC310],第8节),包括对SNMPv3加密机制的完全支持(用于身份验证和隐私)。

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.

此外,不建议部署SNMPv3之前的SNMP版本。相反,建议部署SNMPv3并启用加密安全性。然后,客户/运营商应负责确保授予访问此MIB模块实例权限的SNMP实体已正确配置为仅授予那些拥有确实获取或设置(更改/创建/删除)对象的合法权限的主体(用户)访问对象。
