The SNMP Management Framework presently consists of five major components:
SNMP管理框架目前由五个主要组件组成：
o An overall architecture, described in RFC 2571 [1].
o RFC 2571[1]中描述的总体架构。
o Mechanisms for describing and naming objects and events for the purpose of management. The first version of this Structure of Management Information (SMI) is called SMIv1 and described in STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The second version, called SMIv2, is described in STD 58, RFC 2578 [5], STD 58, RFC 2579 [6] and STD 58, RFC 2580 [7].
o 为管理目的描述和命名对象和事件的机制。这种管理信息结构（SMI）的第一个版本称为SMIv1，并在STD 16、RFC 1155[2]、STD 16、RFC 1212[3]和RFC 1215[4]中进行了描述。第二个版本称为SMIv2，在STD 58、RFC 2578[5]、STD 58、RFC 2579[6]和STD 58、RFC 2580[7]中进行了描述。
o Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in STD 15, RFC 1157 [8]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [9] and RFC
o 用于传输管理信息的消息协议。SNMP消息协议的第一个版本称为SNMPv1，在STD 15、RFC 1157[8]中进行了描述。SNMP消息协议的第二个版本不是Internet标准跟踪协议，称为SNMPv2c，并在RFC 1901[9]和RFC中进行了描述
1906 [10]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [10], RFC 2572 [11] and RFC 2574 [12].
1906 [10]. 消息协议的第三个版本称为SNMPv3，在RFC 1906[10]、RFC 2572[11]和RFC 2574[12]中进行了描述。
o Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in STD 15, RFC 1157 [8]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [13].
o 访问管理信息的协议操作。STD 15、RFC 1157[8]中描述了第一组协议操作和相关PDU格式。RFC 1905[13]中描述了第二组协议操作和相关PDU格式。
o A set of fundamental applications described in RFC 2573 [14] and the view-based access control mechanism described in RFC 2575 [15].
o RFC 2573[14]中描述的一组基本应用程序和RFC 2575[15]中描述的基于视图的访问控制机制。
Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the mechanisms defined in the SMI.
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中的对象是使用SMI中定义的机制定义的。
This memo specifies a MIB module that is compliant to the SMIv2. A MIB conforming to the SMIv1 can be produced through the appropriate translations. The resulting translated MIB must be semantically equivalent, except where objects or events are omitted because no translation is possible (use of Counter64). Some machine readable information in SMIv2 will be converted into textual descriptions in SMIv1 during the translation process. However, this loss of machine readable information is not considered to change the semantics of the MIB.
此备忘录指定了符合SMIv2的MIB模块。通过适当的翻译，可以生成符合SMIv1的MIB。生成的已翻译MIB必须在语义上等效，除非由于无法翻译而省略了对象或事件（使用计数器64）。在翻译过程中，SMIv2中的一些机器可读信息将转换为SMIv1中的文本描述。但是，这种机器可读信息的丢失不被认为会改变MIB的语义。
The terms in this document are derived either from normal cable system usage, or from the documents associated with the Data Over Cable Service Interface Specification process.
本文档中的术语来源于正常的有线电视系统使用，或与有线电视数据服务接口规范流程相关的文档。
Originally "Community Antenna Television", now used to refer to any cable or hybrid fiber and cable system used to deliver video signals to a community.

2.3. CMTS Cable Modem Termination System.
2.3. CMTS电缆调制解调器终端系统。
A generic term covering a cable bridge or cable router in a head-end. A CMTS acts as the master station in a DOCSIS compliant cable data system. It is the only station that transmits downstream, and it controls the scheduling of upstream transmissions by its associated CMs.
涵盖前端电缆桥架或电缆路由器的通用术语。CMTS充当DOCSIS兼容电缆数据系统中的主站。它是唯一一个下行传输的站点，并且它通过其相关的CMs控制上行传输的调度。
"Data Over Cable Interface Specification". A term referring to the ITU-T J.112 Annex B standard for cable modem systems [20].

"Multimedia Cable Network System". Generally replaced in usage by DOCSIS.
“多媒体有线网络系统”。通常使用DOCSIS替代。
Radio Frequency.
无线电频率
The direction from the subscriber towards the head-end.
从用户到前端的方向。
This MIB provides a set of objects required for the management of DOCSIS compliant Cable Modems (CM) and Cable Modem Termination Systems (CMTS). The specification is derived from the DOCSIS Radio Frequency Interface specification [16]. Please note that the DOCSIS 1.0 standard only requires Cable Modems to implement SNMPv1 and to
此MIB提供了管理符合DOCSIS的电缆调制解调器（CM）和电缆调制解调器终端系统（CMT）所需的一组对象。本规范源自DOCSIS射频接口规范[16]。请注意，DOCSIS 1.0标准仅要求电缆调制解调器来实现SNMPv1和
process IPv4 customer traffic. Design choices in this MIB reflect those requirements. Future versions of the DOCSIS standard are expected to require support for SNMPv3 and IPv6 as well.
处理IPv4客户流量。此MIB中的设计选择反映了这些需求。DOCSIS标准的未来版本预计也需要对SNMPv3和IPv6的支持。
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 [19].
本文件中的关键词“必须”、“不得”、“要求”、“应”、“不应”、“应”、“不应”、“建议”、“可”和“可选”应按照[19]中所述进行解释。
This MIB is structured into seven groups:
该MIB分为七组：
o The docsDevBase group extends the MIB-II 'system' group with objects needed for cable device system management.
o docsDevBase组使用电缆设备系统管理所需的对象扩展MIB-II“系统”组。
o The docsDevNmAccessGroup provides a minimum level of SNMP access security (see Section 3 of [18]).
o docsDevNmAccessGroup提供最低级别的SNMP访问安全性（见[18]第3节）。
o The docsDevSoftware group provides information for network-downloadable software upgrades. See "Handling of Software Upgrades" below..
o DOCSDEVSOFFTWARE组提供有关网络下载软件升级的信息。请参阅下面的“软件升级处理”。。
o The docsDevServer group provides information about the progress of the interaction between the CM or CMTS and various provisioning servers.
o docsDevServer组提供有关CM或CMT与各种供应服务器之间交互进度的信息。
o The docsDevEvent group provides control and logging for event reporting.
o DocsDevent组为事件报告提供控制和日志记录。
o The docsDevFilter group configures filters at link layer and IP layer for bridged data traffic. This group consists of a link-layer filter table, docsDevFilterLLCTable, which is used to manage the processing and forwarding of non-IP traffic; an IP packet classifier table, docsDevFilterIpTable, which is used to map classes of packets to specific policy actions; a policy table, docsDevFilterPolicyTable, which maps zero or more policy actions onto a specific packet classification, and one or more policy action tables.
o docsDevFilter组在链路层和IP层为桥接数据流量配置过滤器。该组由链路层筛选器表docsDevFilterLLCTable组成，用于管理非IP流量的处理和转发；IP数据包分类器表docsDevFilterIpTable，用于将数据包类映射到特定策略操作；策略表docsDevFilterPolicyTable（将零个或多个策略操作映射到特定数据包分类）和一个或多个策略操作表。
At this time, this MIB specifies only one policy action table, docsDevFilterTosTable, which allows the manipulation of the type of services bits in an IP packet based on matching some criteria. The working group may add additional policy types and action tables in the future, for example to allow QOS to modem service identifier assignment based on destination.
此时，此MIB仅指定一个策略操作表docsDevFilterTosTable，该表允许基于匹配某些条件操纵IP数据包中的服务类型位。工作组将来可以添加额外的策略类型和操作表，例如，以允许基于目的地的QOS到调制解调器服务标识符分配。
o The docsDevCpe group provides control over which IP addresses may be used by customer premises equipment (e.g. PCs) serviced by a given cable modem. This provides anti-spoofing control at the point of origin for a large cable modem system. This group is separate from docsDevFilter primarily as this group is only implemented on the Cable Modem (CM) and MUST NOT be implemented on the Cable Modem Termination System (CMTS).
o docsDevCpe组控制由给定电缆调制解调器提供服务的客户场所设备（如PC）可以使用哪些IP地址。这为大型电缆调制解调器系统在原点提供了反欺骗控制。此组与docsDevFilter分开，主要是因为此组仅在电缆调制解调器（CM）上实现，不得在电缆调制解调器终端系统（CMTS）上实现。
The Cable Modem software upgrade process is documented in [16]. From a network management station, the operator:
[16]中记录了电缆调制解调器软件升级过程。从网络管理站，运营商：
o sets docsDevSwServer to the address of the TFTP server for software upgrades
o 将docsDevSwServer设置为用于软件升级的TFTP服务器的地址
o sets docsDevSwFilename to the file pathname of the software upgrade image
o 将docsDevSwFilename设置为软件升级映像的文件路径名
o sets docsDevSwAdminStatus to upgrade-from-mgt
o 将docsDevSwAdminStatus设置为从mgt升级
One reason for the SNMP-initiated upgrade is to allow loading of a temporary software image (e.g., special diagnostic software) that differs from the software normally used on that device without changing the provisioning database.
SNMP启动升级的一个原因是允许加载与该设备上通常使用的软件不同的临时软件映像（例如，特殊诊断软件），而无需更改配置数据库。
Note that software upgrades should not be accepted blindly by the cable device. The cable device may refuse an upgrade if:
请注意，电缆设备不应盲目接受软件升级。如果出现以下情况，电缆设备可能会拒绝升级：
o The download is incomplete.
o 下载不完整。
o The file contents are incomplete or damaged.
o 文件内容不完整或已损坏。
o The software is not intended for that hardware device (may include the case of a feature set that has not been purchased for this device).
o 软件不适用于该硬件设备（可能包括尚未为此设备购买的功能集的情况）。
This MIB provides control facilities for reporting events through syslog, traps, and non-volatile logging. If events are reported through traps, the specified conventions must be followed. Other means of event reporting are outside the scope of this document.
此MIB提供了通过系统日志、陷阱和非易失性日志记录报告事件的控制功能。如果通过陷阱报告事件，则必须遵循指定的约定。其他事件报告方式不在本文件范围内。
The definition and coding of events is vendor-specific. In deference to the network operator who must troubleshoot multi-vendor networks, the circumstances and meaning of each event should be reported as human-readable text. Vendors SHOULD provide time-of-day clocks in CMs to provide useful timestamping of events.
事件的定义和编码是特定于供应商的。与必须对多供应商网络进行故障排除的网络运营商不同，每个事件的情况和意义应以人类可读文本的形式报告。供应商应在CMs中提供时间时钟，以提供有用的事件时间戳。
For each vendor-specific event that is reportable via TRAP, the vendor must create an enterprise-specific trap definition. Trap definitions MUST include the event reason encoded as DisplayString and should be defined as:
对于每个可通过陷阱报告的特定于供应商的事件，供应商必须创建特定于企业的陷阱定义。陷阱定义必须包括编码为DisplayString的事件原因，并应定义为：
trapName NOTIFICATION-TYPE
OBJECTS {
ifIndex,
eventReason,
other useful objects
}
STATUS current
DESCRIPTION
"trap description"
::= Object Id
trapName NOTIFICATION-TYPE
OBJECTS {
ifIndex,
eventReason,
other useful objects
}
STATUS current
DESCRIPTION
"trap description"
::= Object Id
Note that ifIndex is only included if the event or trap is interface related.
请注意，仅当事件或陷阱与接口相关时，才包括ifIndex。
An example (fake) vendor defined trap might be:
供应商定义的陷阱示例（假）可能是：
xyzVendorModemDropout NOTIFICATION-TYPE
OBJECTS {
eventReason,
xyzModemHighWatermarkCount
}
STATUS current
DESCRIPTION
"Sent by a CMTS when a configurable number of modems
(xyzModemHysteresis) de-register or become unreachable during
the sampling period (5 minutes). Used to warn a management
station about a catastrophic cable plant outage."
::= { xyzTraps 23 }
xyzVendorModemDropout NOTIFICATION-TYPE
OBJECTS {
eventReason,
xyzModemHighWatermarkCount
}
STATUS current
DESCRIPTION
"Sent by a CMTS when a configurable number of modems
(xyzModemHysteresis) de-register or become unreachable during
the sampling period (5 minutes). Used to warn a management
station about a catastrophic cable plant outage."
::= { xyzTraps 23 }
In this example eventReason is a DisplayString providing a human readable error message, and xyzModemHighWatermarkCount is a Gauge32 which indicates the maximum number of modems during the epoch.
在本例中，eventReason是一个显示字符串，提供了一条人类可读的错误消息，而xyzModemHighWatermarkCount是一个仪表32，它指示了历元期间调制解调器的最大数量。
The last digit of the trap OID for enterprise-specific traps must match docsDevEvId. For SNMPv1-capable Network Management systems, this is necessary to correlate the event type to the trap type. Many Network Management systems are only capable of trap filtering on an enterprise and single-last-digit basis.
企业特定陷阱的陷阱OID的最后一位数字必须与docsDevEvId匹配。对于支持SNMPv1的网络管理系统，有必要将事件类型与陷阱类型关联起来。许多网络管理系统只能对企业和最后一位数进行陷阱过滤。
The CM and CMTS MUST provide support for trap message throttling as described below. The network operator can employ message rate throttling or trap limiting by manipulating the appropriate MIB variables.
CM和CMT必须提供对陷阱消息限制的支持，如下所述。网络运营商可以通过操纵适当的MIB变量来采用消息速率限制或陷阱限制。
Network operators may employ either of two rate control methods. In the first method, the device ceases to send traps when the rate exceeds the specified maximum message rate. It resumes sending traps only if reactivated by a network management station request.
网络运营商可采用两种速率控制方法之一。在第一种方法中，当速率超过指定的最大消息速率时，设备停止发送陷阱。仅当网络管理站请求重新激活时，它才恢复发送陷阱。
In the second method, the device resumes sending traps when the rate falls below the specified maximum message rate.
在第二种方法中，当速率低于指定的最大消息速率时，设备恢复发送陷阱。
The network operator configures the specified maximum message rate by setting the measurement interval (in seconds), and the maximum number of traps to be transmitted within the measurement interval. The operator can query the operational throttling state (to determine whether traps are enabled or blocked by throttling) of the device, as well as query and set the administrative throttling state (to manage the rate control method) of the device.
网络运营商通过设置测量间隔（以秒为单位）和测量间隔内要传输的陷阱的最大数量来配置指定的最大消息速率。操作员可以查询设备的操作节流状态（确定是否通过节流启用或阻止陷阱），以及查询和设置设备的管理节流状态（管理速率控制方法）。
Network operators may wish to limit the number of traps sent by a device over a specified time period. The device ceases to send traps when the number of traps exceeds the specified threshold. It resumes sending traps only when the measurement interval has passed.
网络运营商可能希望限制设备在指定时间段内发送的陷阱数量。当陷阱数量超过指定阈值时，设备停止发送陷阱。仅当测量间隔已过时，它才恢复发送陷阱。
The network operator defines the maximum number of traps he is willing to handle and sets the measurement interval to a large number (in hundredths of a second). For this case, the administrative throttling state is set to stop at threshold which is the maximum number of traps.
网络运营商定义他愿意处理的陷阱的最大数量，并将测量间隔设置为一个较大的数字（百分之一秒）。对于这种情况，管理节流状态设置为在阈值停止，阈值是陷阱的最大数量。

The Cable Device MIB provides objects for both LLC and IP protocol filters. The LLC protocol filter entries can be used to limit CM forwarding to a restricted set of network-layer protocols (such as IP, IPX, NetBIOS, and Appletalk).
电缆设备MIB为LLC和IP协议筛选器提供对象。LLC协议筛选器条目可用于将CM转发限制为一组受限的网络层协议（如IP、IPX、NetBIOS和Appletalk）。
The IP protocol filter entries can be used to restrict upstream or downstream traffic based on source and destination IP addresses, transport-layer protocols (such as TCP, UDP, and ICMP), and source and destination TCP/UDP port numbers.
IP协议筛选器条目可用于根据源和目标IP地址、传输层协议（如TCP、UDP和ICMP）以及源和目标TCP/UDP端口号限制上游或下游流量。
In general, a cable modem applies filters (or more properly, classifiers) in an order appropriate to the layering model. Specifically, the inbound MAC (or LLC) layer filters are applied first, then the "special" filters, then the IP layer inbound filters, then the IP layer outbound filters, then any final LLC outbound filters. Since the cable modem does not generally do any IP processing (other than that specified by the filters) the processing of the IP in filters and IP out filters can usually be combined into a single step.
通常，电缆调制解调器按照适合分层模型的顺序应用过滤器（或者更恰当地说，分类器）。具体来说，首先应用入站MAC（或LLC）层过滤器，然后是“特殊”过滤器，然后是IP层入站过滤器，然后是IP层出站过滤器，然后是任何最终的LLC出站过滤器。由于电缆调制解调器通常不进行任何IP处理（由过滤器指定的除外），因此IP in过滤器和IP out过滤器的处理通常可以组合到单个步骤中。

The inbound LLC (or MAC or level-2) filters are contained in the docsDevFilterLLCTable and are applied to level-2 frames entering the cable modem from either the RF MAC interface or from one of the CPE (ethernet or other) interfaces. These filters are used to prohibit the processing and forwarding of certain types of level-2 traffic that may be disruptive to the network. The filters, as currently specified, can be set to cause the modem to either drop frames which match at least one filter, or to process a frame which matches at least filter. Some examples of possible configurations would be to only permit IP (and ARP) traffic, or to drop NETBUEI traffic.
入站LLC（或MAC或2级）过滤器包含在DOCSDEVFILTERLLCC表中，并应用于从RF MAC接口或其中一个CPE（以太网或其他）接口进入电缆调制解调器的2级帧。这些筛选器用于禁止处理和转发可能中断网络的某些类型的2级流量。当前指定的筛选器可以设置为使调制解调器丢弃至少与一个筛选器匹配的帧，或处理至少与一个筛选器匹配的帧。一些可能的配置示例是只允许IP（和ARP）流量，或丢弃NETBUEI流量。
Special filters are applied after the packet is accepted from the MAC layer by the IP module, but before any other processing is done. They are filters that apply only to a very specific class of traffic.
在IP模块从MAC层接受数据包之后，但在完成任何其他处理之前，应用特殊过滤器。它们是仅适用于非常特定类别流量的过滤器。
IP spoofing filters are applied to packets entering the modem from one of the CPE interfaces and are intended to prevent a subscriber from stealing or mis-using IP addresses that were not assigned to the subscriber. If the filters are active (enabled), the source address of the IP packet must match at least one IP address in this table or it is discarded without further processing.
IP欺骗过滤器应用于从CPE接口之一进入调制解调器的数据包，旨在防止订户窃取或误用未分配给订户的IP地址。如果筛选器处于活动状态（已启用），则IP数据包的源地址必须至少与此表中的一个IP地址匹配，否则将被丢弃，而无需进一步处理。
The table can be automatically populated where the first N different IP addresses seen from the CPE side of the cable modem are used to automatically populate the table. The spoofing filters are specified in the docsDevCpeTable and the policy for automatically creating filters in that table is controlled by docsDevCpeEnroll and docsDevCpeMax as well as the network management agent.
当从电缆调制解调器的CPE侧看到的前N个不同IP地址用于自动填充表格时，可以自动填充表格。欺骗筛选器在docsDevCpeTable中指定，自动在该表中创建筛选器的策略由DocsdevcPetroll和docsDevCpeMax以及网络管理代理控制。
The SNMP access filters are applied to SNMP packets entering from any interface and destined for the cable modem. If the packets enter from a CPE interface, the SNMP filters are applied after the IP spoofing filters. The filters only apply to SNMPv1 or SNMPv2c traffic, and are not consulted for SNMPv3 traffic (and need not be implemented by a v3 only agent). SNMPv3 access control is specified in the User Security Model MIB in [12].
SNMP访问筛选器应用于从任何接口进入并发送到电缆调制解调器的SNMP数据包。如果数据包从CPE接口进入，则在IP欺骗过滤器之后应用SNMP过滤器。这些过滤器仅适用于SNMPv1或SNMPv2c流量，不适用于SNMPv3流量（并且不需要仅由v3代理实现）。SNMPv3访问控制在[12]中的用户安全模型MIB中指定。
The IP Filtering table acts as a classifier table. Each row in the table describes a template against which IP packets are compared. The template includes source and destination addresses (and their associated masks), upper level protocol (e.g. TCP, UDP), source and destination port ranges, TOS and TOS mask. A row also contains interface and traffic direction match values which have to be considered in combination. All columns of a particular row must match the appropriate fields in the packet, and must match the interface and direction items for the packet to result in a match to the packet.
IP筛选表充当分类器表。表中的每一行都描述了一个用于比较IP数据包的模板。该模板包括源和目标地址（及其相关掩码）、上层协议（如TCP、UDP）、源和目标端口范围、TOS和TOS掩码。行还包含必须结合考虑的接口和交通方向匹配值。特定行的所有列必须与数据包中的相应字段匹配，并且必须与数据包的接口和方向项匹配，才能与数据包匹配。
When classifying a packet, the table is scanned beginning with the lowest number filter. If the agent finds a match, it applies the group of policies specified. If the matched filter has the continue bit set, the agent continues the scan possibly matching additional filters and applying additional policies. This allows the agent to take one set of actions for the 24.0.16/255.255.255.0 group and one set of actions for telnet packets to/from 24.0.16.30 and these sets of actions may not be mutually exclusive.
对数据包进行分类时，将从数字最少的筛选器开始扫描表。如果代理找到匹配项，它将应用指定的策略组。如果匹配的筛选器设置了continue位，则代理将继续扫描，可能会匹配其他筛选器并应用其他策略。这允许代理为24.0.16/255.255.255.0组执行一组操作，并为从24.0.16.30到24.0.16.30的telnet数据包执行一组操作，并且这些操作不能相互排斥。
Once a packet is matched, one of three actions happen based on the setting of docsDevFilterIpControl in the row. The packet may be dropped, in which case no further processing is required. The packet may be accepted and processing of the packet continues. Lastly, the packet may have a set of policy actions applied to it. If docsDevFilterIpContinue is set to true, scanning of the table continues and additional matches may result.
匹配数据包后，将根据行中docsDevFilterIpControl的设置执行三个操作之一。包可能被丢弃，在这种情况下，不需要进一步处理。可以接受分组，并且分组的处理继续。最后，数据包可以应用一组策略操作。如果docsDevFilterIpContinue设置为true，则表的扫描将继续，并可能导致其他匹配。
When a packet matches, and docsDevFilterIpControl in the filter matched is set to 'policy', the value of docsDevFilterIpPolicyId is used as a selector into the docsDevFilterPolicyTable. The first level of indirection may result in zero or more actions being taken based on the match. The docsDevFilterPolicyTable is scanned in row order and all rows where docsDevFilterPolicyId equals docsDevFilterIpPolicyId have the action specified by docsDevFilterPolicyValue 'executed'. For example, a value pointing to an entry in the docsDevFilterTosTable may result in the re-writing of the TOS bits in the IP packet which was matched. Another possibility may be to assign an output packet to a specific output upstream queue. An even more complex action might be to re-write the TOS value, assign the packet to an upstream service ID, and drop it into a particular IPSEC tunnel.
当数据包匹配且匹配的筛选器中的docsDevFilterIpControl设置为“策略”时，docsDevFilterIpPolicyId的值将用作docsDevFilterPolicyTable中的选择器。第一级间接寻址可能导致根据匹配执行零个或多个操作。docsDevFilterPolicyTable按行顺序扫描，docsDevFilterPolicyId等于docsDevFilterIpPolicyId的所有行都具有docsDevFilterPolicyValue“已执行”指定的操作。例如，指向docsDevFilterTosTable中的条目的值可能导致在匹配的IP分组中重新写入TOS位。另一种可能是将输出分组分配给特定的输出上游队列。更复杂的操作可能是重新写入TOS值，将数据包分配给上游服务ID，并将其放入特定的IPSEC隧道。

This table describes some special processing for packets originating from either the first or second CPE device which results in their queuing on to special upstream traffic queues and for the "gold" service results in having the packets marked with a TOS of 5. The 10, 20, 60 and 65 entries are generic entries that would generally be applied to all traffic to this CM. The 30, 40 and 45 entries are specific to a particular CPE's service assignments. The ordering here is a bit contrived, but is close to what may actually be required by the operator to control various classes of customers.
该表描述了对源自第一或第二CPE设备的数据包的一些特殊处理，这些数据包导致它们排队到特殊的上游业务队列，而对于“黄金”服务，这些数据包的TOS标记为5。10、20、60和65项为一般性项，通常适用于该CM的所有流量。30、40和45条目特定于特定CPE的服务分配。这里的订购有点做作，但接近运营商控制各类客户的实际要求。
Lastly, any outbound LLC filters are applied to the packet just prior to it being emitted on the appropriate interface. This MIB does not specify any outbound LLC filters, but it is anticipated that the QOS additions to the DOCSIS standard may include some outbound LLC filtering requirements. If so, those filters would be applied as described here.
最后，任何出站LLC筛选器都将在数据包在适当接口上发出之前应用于该数据包。该MIB未指定任何出站LLC过滤器，但预计DOCSIS标准中增加的QOS可能包括一些出站LLC过滤要求。如果是这样，这些过滤器将按此处所述应用。

Any IP packet can theoretically match multiple rows of

If the packet matches that filter (which means that it matches ALL criteria for that row), actions appropriate to docsDevFilterIpControl and docsDevFilterPolicyId are taken. If the packet was discarded processing is complete. If docsDevFilterIpContinue is set to true, the filter comparison continues with the next row in the table looking for additional matches.
这张桌子。当考虑数据包时，表按行索引顺序扫描（例如，在过滤器20之前检查过滤器10）。如果数据包与该筛选器匹配（这意味着它与该行的所有条件匹配），则将采取适用于docsDevFilterIpControl和docsDevFilterPolicyId的操作。如果数据包被丢弃，则处理完成。如果docsDevFilterIpContinue设置为true，则过滤器比较将继续进行，并在表中的下一行中查找其他匹配项。
If the packet matches no filter in the table, the packet is accepted or dropped for further processing based on the setting of docsDevFilterIpDefault. If the packet is accepted, the actions specified by policy group 0 (e.g. the rows in docsDevFilterPolicyTable which have a value of 0 for docsDevFilterPolicyId) are taken if that policy group exists.
如果数据包与表中的任何筛选器都不匹配，则会根据docsDevFilterIpDefault的设置接受或丢弃该数据包以进行进一步处理。如果数据包被接受，则在策略组0（例如docsDevFilterPolicyTable中docsDevFilterPolicyId值为0的行）存在的情况下，将执行该策略组0指定的操作。

This MIB relates to a system which will provide metropolitan public internet access. As such, improper manipulation of the objects represented by this MIB may result in denial of service to a large number of end-users. In addition, manipulation of the
该MIB涉及一个提供大都市公共互联网接入的系统。因此，对该MIB表示的对象的不当操作可能会导致大量最终用户拒绝服务。此外，操纵
docsDevNmAccessTable, docsDevFilterLLCTable, docsDevFilterIpTable and the elements of the docsDevCpe group may allow an end-user to increase their service levels, spoof their IP addresses, change the permitted management stations, or affect other end-users in either a positive or negative manner.
docsdevnmaccestable、docsDevFilterLLCTable、docsdevfilterptable和docsDevCpe组的元素可允许最终用户增加其服务级别、欺骗其IP地址、更改允许的管理站，或以积极或消极的方式影响其他最终用户。
There are a number of management objects defined in this MIB that have 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. In addition to those mentioned above:
此MIB中定义了许多管理对象，它们的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。除上述内容外：
o The use of docsDevNmAccessTable to specify management stations is considered to be only limited protection and does not protect against attacks which spoof the management station's IP address. The use of stronger mechanisms such as SNMPv3 security should be considered where possible. Specifically, SNMPv3 VACM and USM MUST be used with any v3 agent which implements this MIB. Administrators may also wish to consider whether even read access to docsDevNmAccessTable may be undesirable under certain circumstances.
o 使用docsdevnmaccestable指定管理站被认为只是有限的保护，不能防止欺骗管理站IP地址的攻击。在可能的情况下，应考虑使用更强的机制，如SNMPv3安全性。具体来说，SNMPv3 VACM和USM必须与实现此MIB的任何v3代理一起使用。管理员还可以考虑在某些情况下是否对DOCSsDeMnAccess稳定的读取访问可能是不可取的。
o The CM may have its software changed by the actions of the management system. An improper software load may result in substantial vulnerabilities and the loss of the ability of the management system to control the cable modem.
o CM可能会因管理系统的行为而更改其软件。不正确的软件加载可能会导致严重的漏洞，并使管理系统失去控制电缆调制解调器的能力。
o The device may be reset by setting docsDevResetNow = true(1). This causes the device to reload its configuration files as well as eliminating all previous non-persistent network management settings. As such, this may provide a vector for attacking the system.
o 可通过设置DOCSDVRESETNOW=true（1）重置设备。这会导致设备重新加载其配置文件，并消除所有以前的非持久性网络管理设置。因此，这可能提供攻击系统的向量。
o Setting docsDevEvThrottleAdminStatus = unconstrained(1) (which is also the DEFVAL) may cause flooding of traps, which can disrupt network service.
o 设置docsDevEvThrottleAdminStatus=unconstraint（1）（这也是deffal）可能会导致陷阱泛滥，从而中断网络服务。
This MIB does not affect confidentiality of services on a cable modem system. [20] specifies the implementation of the DOCSIS Baseline privacy mechanism. The working group expects to issue a MIB for the management of this mechanism at a later time.
此MIB不会影响电缆调制解调器系统上服务的机密性。[20] 指定DOCSIS基线隐私机制的实现。工作组预计将在稍后发布一份管理这一机制的MIB。
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/create/delete) the objects in this MIB.
SNMPv1本身不是一个安全的环境。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中的对象。
It is recommended that the implementers consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model [12] and the View-based Access Control Model [15] is recommended.
建议实施者考虑SNMPv3框架提供的安全特性。具体而言，建议使用基于用户的安全模型[12]和基于视图的访问控制模型[15]。
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/create/delete) them.
然后，客户/用户有责任确保授予对此MIB实例访问权限的SNMP实体被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）对对象的访问权限。
