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].
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RFC 2119[RFC2119]中所述进行解释。
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 [RFC2571].
o RFC 2571[RFC2571]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 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC 1215 [RFC1215]. The second version, called SMIv2, is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580].
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[RFC1155]、STD 16、RFC 1212[RFC1212]和RFC 1215[RFC1215]中进行了描述。第二个版本称为SMIv2，在STD 58、RFC 2578[RFC2578]、STD 58、RFC 2579[RFC2579]和STD 58、RFC 2580[RFC2580]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 [RFC1157]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [RFC1901] and RFC 1906 [RFC1906]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [RFC1906], RFC 2572 [RFC2572] and RFC 2574 [RFC2574].
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[RFC1157]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，在RFC 1901[RFC1901]和RFC 1906[RFC1906]中进行了描述。消息协议的第三个版本称为SNMPv3，在RFC 1906[RFC1906]、RFC 2572[RFC2572]和RFC 2574[RFC2574]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 [RFC1157]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [RFC1905].
o 访问管理信息的协议操作。STD 15、RFC 1157[RFC1157]中描述了第一组协议操作和相关PDU格式。RFC 1905[RFC1905]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 [RFC2573] and the view-based access control mechanism described in RFC 2575 [RFC2575].
o RFC 2573[RFC2573]中描述的一组基本应用程序和RFC 2575[RFC2575]中描述的基于视图的访问控制机制。
A more detailed introduction to the current SNMP Management Framework can be found in RFC 2570 [RFC2570].
有关当前SNMP管理框架的更详细介绍，请参见RFC 2570[RFC2570]。
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 MIB defined in this memo provides the scheduling of actions periodically or at specified dates and times. The actions can be used to realize on-duty / off-duty schedules or to trigger management functions in a distributed management application.
本备忘录中定义的MIB定期或在指定日期和时间提供行动计划。这些操作可用于实现值班/下班计划，或触发分布式管理应用程序中的管理功能。
Schedules can be enabled or disabled by modifying a control object. This allows for pre-configured schedules which are activated or deactivated by some other management functions.
可以通过修改控件对象来启用或禁用明细表。这允许通过一些其他管理功能激活或停用预先配置的计划。
The term `scheduler' is used throughout this memo to refer to the entity which implements the scheduling MIB and which invokes the actions at the specified points in time.
本备忘录中使用的术语“调度器”是指实现调度MIB并在指定时间点调用操作的实体。
Periodic schedules are based on fixed time periods between the initiation of scheduled actions. Periodic schedules are defined by specifying the number of seconds between two initiations. The time needed to complete the action is usually not known by the scheduler and does therefore not influence the next scheduling point.
定期计划基于启动计划行动之间的固定时间段。定期计划通过指定两次启动之间的秒数来定义。调度程序通常不知道完成操作所需的时间，因此不会影响下一个调度点。
Implementations must guarantee that action invocations will not occur before their next scheduled time. However, implementations may be forced to delay invocations in the face of local constraints (e.g., a heavy load on higher-priority tasks). An accumulation of such delays would result in a drift of the scheduling interval with respect to time, and should be avoided.
实现必须保证操作调用不会在下一个计划时间之前发生。然而，在面对局部约束（例如，高优先级任务的繁重负载）时，实现可能会被迫延迟调用。此类延迟的累积将导致调度间隔相对于时间的漂移，应予以避免。
Scheduled actions collecting statistical data should retrieve time stamps from the data source and not rely on the accuracy of the periodic scheduler in order to obtain accurate statistics.
收集统计数据的计划操作应该从数据源检索时间戳，而不是依赖周期计划程序的准确性来获得准确的统计数据。
Calendar schedules trigger scheduled actions at specified days of the week and days of the month. Calendar schedules are therefore aware of the notion of months, days, weekdays, hours and minutes.
日历计划在一周的指定日期和一个月的指定日期触发计划的操作。因此，日历时间表了解月、日、工作日、小时和分钟的概念。
It is possible to specify multiple values for each calendar item. This provides a mechanism for defining complex schedules. For example, a schedule could be defined which triggers an action every 15 minutes on a given weekday.
可以为每个日历项指定多个值。这提供了一种定义复杂计划的机制。例如，可以定义一个时间表，在给定的工作日每15分钟触发一次操作。
Months, days and weekdays are specified using the objects schedMonth, schedDay and schedWeekDay of type BITS. Setting multiple bits to one in these objects causes an OR operation. For example, setting the bits monday(1) and friday(5) in schedWeekDay restricts the schedule to Mondays and Fridays.
使用BITS类型的对象schedMonth、schedDay和schedWeekDay指定月、日和工作日。将这些对象中的多个位设置为一会导致OR操作。例如，在schedWeekDay中设置位monday（1）和friday（5）将日程限制为周一和周五。
The bit fields for schedMonth, schedDay and schedWeekDay are combined using an AND operation. For example, setting the bits june(5) and july(6) in schedMonth and combining it with the bits monday(1) and friday(5) set in schedWeekDay will result in a schedule which is restricted to every Monday and Friday in the months June and July. Wildcarding of calendar items is achieved by setting all bits to one.
schedMonth、schedDay和schedWeekDay的位字段使用and操作组合。例如，在schedMonth中设置bits june（5）和july（6），并将其与schedWeekDay中设置的bits monday（1）和friday（5）相结合，将生成一个仅限于6月和7月的每个周一和周五的计划。通过将所有位设置为一，可以实现日历项的通配符。
It is possible to define calendar schedules that will never trigger an action. For example, one can define a calendar schedule which should trigger an action on February 31st. Schedules like this will simply be ignored by the scheduler.
可以定义永远不会触发操作的日历计划。例如，可以定义一个日历计划，该计划应在2月31日触发一个操作。这样的计划将被调度器忽略。
Finally, calendar schedules are always expressed in local time. A scalar, schedLocalTime, is provided so that a manager can retrieve the notion of local time and the offset to GMT time.
最后，日历时间表总是以当地时间表示。提供了一个标量schedLocalTime，以便管理器可以检索本地时间的概念和GMT时间的偏移量。
One-shot Schedules are similar to calendar schedules. The difference between a calendar schedule and a one-shot schedule is that a one-shot schedule will automatically disable itself once an action has been invoked.
一次性计划类似于日历计划。日历计划和一次性计划之间的区别在于，一旦调用某个操作，一次性计划将自动禁用自身。
A time transition occurs when the Schedule MIB's notion of time (as reported by schedLocalTime) is changed so that time continuity is lost. Time transitions may be caused by daylight savings times or administrative changes of the system's notion of time.
当Schedule MIB的时间概念（如schedLocalTime所报告的）发生更改，导致时间连续性丢失时，就会发生时间转换。时间转换可能由夏令时或系统时间概念的管理更改引起。
There are two possible situations when a time transition occurs.
发生时间转换时有两种可能的情况。
First, time may be set backwards, in which case particular times will appear to occur twice. These are called 'ambiguous times'. Second, time may be set forwards, in which case particular times will not occur. These are called 'nonexistent times'.
首先，时间可以向后设置，在这种情况下，特定时间将出现两次。这些被称为“模糊时间”。第二，时间可以向前设置，在这种情况下，不会出现特定的时间。这些被称为“不存在的时间”。
When an action is configured in the Schedule MIB to occur at an ambiguous time, the action will be invoked at all occurrences of the ambiguous time. For example, if an action is scheduled to occur at 2:10 am, and a time transition occurs at 3:00 am which sets the clock back to 2:00 am, the action will be invoked twice.
当在Schedule MIB中将某个操作配置为在不明确的时间发生时，该操作将在该不明确的时间的所有事件中调用。例如，如果某个操作计划在凌晨2:10发生，并且在凌晨3:00发生时间转换，将时钟设置回凌晨2:00，则该操作将被调用两次。
When an action is configured in the Schedule MIB to occur at a nonexistent time, the action will not be invoked at all. For example, if an action is scheduled to occur at 2:10 am, and a time transition occurs at 2:00 am which sets the clock to 3:00 am, the action will not be invoked.
当在ScheduleMIB中配置一个操作在不存在的时间发生时，将根本不会调用该操作。例如，如果某个操作计划在凌晨2:10发生，并且在凌晨2:00发生时间转换，将时钟设置为凌晨3:00，则不会调用该操作。
Scheduled actions are modeled by SNMP set operations on local MIB variables. Scheduled actions described in this MIB are further restricted to objects of type INTEGER. This restriction does not limit the usefulness of the MIB. Simple schedules such as on-duty / off-duty schedules for resources that have a status MIB object (e.g. ifAdminStatus) are possible.
计划的操作由对本地MIB变量的SNMP集操作建模。此MIB中描述的计划操作进一步限制为INTEGER类型的对象。此限制并不限制MIB的用途。对于具有状态MIB对象（例如ifAdminStatus）的资源，可以使用简单的时间表，例如值班/下班时间表。
More complex actions can be realized by triggering a management script which is responsible for performing complex state transitions. A management script can also be used to perform SNMP set operations on remote SNMP engines.
通过触发负责执行复杂状态转换的管理脚本，可以实现更复杂的操作。管理脚本还可用于在远程SNMP引擎上执行SNMP集操作。

DESCRIPTION
"The set of days in a month on which a scheduled action
should take place. There are two sets of bits one can
use to define the day within a month:
Enumerations starting with the letter 'd' indicate a day in a month relative to the first day of a month. The first day of the month can therefore be specified by setting the bit d1(0) and d31(30) means the last day of a month with 31 days.
以字母“d”开头的枚举表示一个月中的某一天相对于一个月的第一天。因此，可以通过设置位d1（0）来指定月份的第一天，d31（30）表示一个月的最后一天（31天）。
Enumerations starting with the letter 'r' indicate a day in a month in reverse order, relative to the last day of a month. The last day in the month can therefore be specified by setting the bit r1(31) and r31(61) means the first day of a month with 31 days.
以字母“r”开头的枚举表示一个月中的一天，其顺序与一个月的最后一天相反。因此，可以通过设置位r1（31）来指定月份的最后一天，并且r31（61）表示一个月的第一天（31天）。
Setting multiple bits will include several days in the set of possible days for this schedule. Setting all bits will cause the scheduler to ignore the day within a month.
设置多个位将在此计划的可能天数集中包括几天。设置所有位将导致计划程序忽略一个月内的一天。
Setting all bits starting with the letter 'd' or the letter 'r' will also cause the scheduler to ignore the day within a month.
设置以字母“d”或字母“r”开头的所有位也会导致计划程序忽略一个月内的某一天。

This section presents some examples how the scheduling MIB can be used to schedule scripts with the Script MIB [RFC3165] or to realize on-duty/off-duty schedules by modifying status objects of other MIB modules.
本节给出了一些示例，说明如何使用调度MIB使用脚本MIB[RFC3165]调度脚本，或通过修改其他MIB模块的状态对象来实现值班/下班调度。
It is assumed that the schedule entry is owned by schedOwner = "joe" and its name is schedName = "ping". The instance identifier for the scheduling entry is therefore 3.106.111.101.4.112.105.110.103.

A similar configuration could be used to control other schedules. For example, one could change the "if-on" and "if-off" schedules to enable and disable the periodic scheduler defined in the first example.
类似的配置可用于控制其他计划。例如，可以更改“if on”和“if off”计划，以启用和禁用第一个示例中定义的定期计划程序。
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.
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。
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 RFC 2574 [RFC2574] and the View-based Access Control Model RFC 2575 [RFC2575] 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RFC 2574[RFC2574]和基于视图的访问控制模型RFC 2575[RFC2575]。
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。
Scheduled SNMP set operations must use the security credentials that were present when the corresponding row in the scheduling entry was created. An implementation must therefore record and maintain the credentials for every scheduling entry.
计划的SNMP集操作必须使用创建计划项中相应行时存在的安全凭据。因此，实现必须记录和维护每个调度条目的凭据。
An implementation must ensure that access control rules are applied when doing the set operation. This is accomplished by calling the isAccessAllowed abstract service interface defined in RFC 2571 [RFC2571]:
实现必须确保在执行set操作时应用访问控制规则。这是通过调用RFC 2571[RFC2571]中定义的isAccessAllowed抽象服务接口来实现的：
statusInformation = -- success or errorIndication
isAccessAllowed(
IN securityModel -- Security Model in use
IN securityName -- principal who wants to access
IN securityLevel -- Level of Security
IN viewType -- read, write, or notify view
IN contextName -- context containing variableName
IN variableName -- OID for the managed object
)
statusInformation = -- success or errorIndication
isAccessAllowed(
IN securityModel -- Security Model in use
IN securityName -- principal who wants to access
IN securityLevel -- Level of Security
IN viewType -- read, write, or notify view
IN contextName -- context containing variableName
IN variableName -- OID for the managed object
)
The securityModel, securityName and securityLevel parameters are set to the values that were recorded when the scheduling entry was created. The viewType parameter must select the write view and the contextName and variableName parameters are taken from the schedContextName and schedVariableName values of the scheduling entry.
securityModel、securityName和securityLevel参数设置为创建调度条目时记录的值。viewType参数必须选择写入视图，contextName和variableName参数取自调度条目的schedContextName和schedVariableName值。
This MIB limits scheduled actions to objects in the local MIB. This avoids security problems with the delegation of access rights. However, it might be possible for a user of this MIB to own some schedules that might trigger far in the future. This can cause security risks if the security administrator did not properly update the access control lists when a user is withdrawn from an SNMP engine. Therefore, entries in the schedTable SHOULD be cleaned up whenever a user is removed from an SNMP engine.
此MIB将计划的操作限制为本地MIB中的对象。这样就避免了访问权委托的安全问题。但是，此MIB的用户可能拥有一些在将来可能触发的计划。如果安全管理员在用户从SNMP引擎中退出时未正确更新访问控制列表，则可能会导致安全风险。因此，每当从SNMP引擎中删除用户时，应清除schedTable中的条目。
To facilitate the provisioning of access control by a security administrator using the View-Based Access Control Model (VACM) defined in RFC 2575 [RFC2575] for tables in which multiple users may need to independently create or modify entries, the initial index is used as an "owner index". Such an initial index has a syntax of
为了方便安全管理员使用RFC 2575[RFC2575]中定义的基于视图的访问控制模型（VACM）为多个用户可能需要独立创建或修改条目的表提供访问控制，初始索引用作“所有者索引”。这种初始索引的语法为
SnmpAdminString, and can thus be trivially mapped to a securityName or groupName as defined in VACM, in accordance with a security policy.
SNMPAdministring，因此可以根据安全策略简单地映射到VACM中定义的securityName或groupName。
All entries in related tables belonging to a particular user will have the same value for this initial index. For a given user's entries in a particular table, the object identifiers for the information in these entries will have the same subidentifiers (except for the "column" subidentifier) up to the end of the encoded owner index. To configure VACM to permit access to this portion of the table, one would create vacmViewTreeFamilyTable entries with the value of vacmViewTreeFamilySubtree including the owner index portion, and vacmViewTreeFamilyMask "wildcarding" the column subidentifier. More elaborate configurations are possible.
相关表中属于特定用户的所有条目对此初始索引具有相同的值。对于特定表中的给定用户项，这些项中信息的对象标识符在编码的所有者索引结束之前将具有相同的子标识符（除了“列”子标识符）。要将VACM配置为允许访问表的这一部分，可以创建vacmViewTreeFamilyTable条目，其值为vacmViewTreeFamilySubtree，包括所有者索引部分，以及VACMVIEWTREEFAMILYMAK“通配符”列子标识符。更复杂的配置是可能的。
