此备忘录定义了管理信息库（MIB）的一部分，用于Internet社区中的网络管理协议。特别是，它描述了用于管理基于ATM的接口、设备、网络和服务的对象。
This memo replaces RFC 1695 [24]. Changes relative to RFC 1695 are summarized in the MIB module's REVISION clause.
本备忘录取代RFC 1695[24]。与RFC 1695相关的变更汇总在MIB模块的修订条款中。
Textual Conventions used in this MIB are defined in [6] and [19].
[6]和[19]中定义了此MIB中使用的文本约定。
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：
0 An overall architecture, described in RFC 2271 [1].
0 RFC 2271[1]中描述的总体架构。
0 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 RFC 1902 [5], RFC 1903 [6] and RFC 1904 [7].
0用于描述和命名对象和事件以进行管理的机制。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RFC 1902[5]、RFC 1903[6]和RFC 1904[7]中进行了描述。
0 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 1906 [10].
0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互联网标准跟踪协议，称为SNMPv2c，在RFC 1901[9]和RFC 1906[10]中进行了描述。
The third version of the message protocol is called SNMPv3 and described in RFC 1906 [10], RFC 2272 [11] and RFC 2274 [12].
消息协议的第三个版本称为SNMPv3，在RFC 1906[10]、RFC 2272[11]和RFC 2274[12]中进行了描述。
0 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].
0用于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。
0 A set of fundamental applications described in RFC 2273 [14] and the view-based access control mechanism described in RFC 2275 [15].
0 RFC 2273[14]中描述的一组基本应用程序和RFC 2275[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 (e.g., 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（例如，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。
Some basic ATM terminologies are described in this section to facilitate defining the ATM managed objects.
本节介绍了一些基本的ATM术语，以便于定义ATM管理对象。
There are two distinct types of ATM virtual connections: Virtual Channel Connections (VCCs) and Virtual Path Connection (VPCs). As shown in Figures 1 and 2, ATM virtual connections consist of concatenated series of virtual links which forms a path between two end points, with each concatenation occurring at an ATM switch. Virtual links of VCCs are called Virtual Channel Links (VCLs). Virtual links of VPCs are called Virtual Path Links (VPLs). The VCI and VPI fields in the ATM cell header associate each cell of a VCC with a particular VCL over a given physical link. The VPI field in the ATM cell header associates each cell of a VPC with a particular VPL over a given physical link. Switches route cells between VCLs (or VPLs) via a cross-connect function according to the cells' VCI/VPI (or VPI) values.
有两种不同类型的ATM虚拟连接：虚拟通道连接（VCC）和虚拟路径连接（VPC）。如图1和图2所示，ATM虚拟连接由串联的一系列虚拟链路组成，这些虚拟链路在两个端点之间形成一条路径，每个串联发生在ATM交换机上。VCC的虚拟链路称为虚拟信道链路（VCL）。专有网络的虚拟链路称为虚拟路径链路（VPL）。ATM信元报头中的VCI和VPI字段将VCC的每个信元与给定物理链路上的特定VCL相关联。ATM信元报头中的VPI字段将VPC的每个信元与给定物理链路上的特定VPL相关联。根据单元的VCI/VPI（或VPI）值，通过交叉连接功能在VCL（或VPL）之间切换单元路由。

A single ATM end-system or switch does not support the whole end-to-end span of a VCC (or VPC). Rather, multiple ATM end-systems and/or switches each support one piece of the VCC (or VPC). That is, each ATM end-system (or ATM switch) at one end of the VCC/VPC supports its end of the VCC/VPC plus the VCL or VPL on its external interface, and each switch through which the VCC/VPC passes supports the pair of VCLs/VPLs on its external interfaces as well as the cross-connection of those VCLs/VPLs. Thus, the end-to-end management of a VCC or VPC is achieved only by appropriate management of its individual pieces in combination.
单个ATM端系统或交换机不支持VCC（或VPC）的整个端到端范围。相反，多个ATM终端系统和/或交换机都支持一个VCC（或VPC）。也就是说，VCC/VPC一端的每个ATM端系统（或ATM交换机）支持其VCC/VPC端及其外部接口上的VCL或VPL，VCC/VPC通过的每个交换机支持其外部接口上的VCL/VPL对以及这些VCL/VPL的交叉连接。因此，VCC或VPC的端到端管理只能通过组合适当管理其各个部件来实现。
Note that for management purposes, an ATM network may be viewed as a large distributed switch by hiding all the network's internal connectivity as being internal to the distributed switch (as shown in Figure 2a). This model may for example be used for Customer Network Management (CNM) purposes.
请注意，出于管理目的，ATM网络可以通过将所有网络的内部连接隐藏为分布式交换机的内部连接而被视为大型分布式交换机（如图2a所示）。例如，该模型可用于客户网络管理（CNM）目的。

A VCC has a set of traffic characteristics (i.e., bandwidth parameters, service category parameters, etc.). VCLs inherit their traffic characteristics from the VCC of which they are a part. VCCs are bi-directional by definition. However, the traffic parameters in the two directions of a connection can be symmetric or asymmetric, i.e., the two directions can have the same or different traffic flows. A uni-directional traffic flow across a VCC is achieved by assigning a zero bandwidth in one direction. Note that in addition to the bandwidth required by the user traffic flow, bandwidth is also required for OAM cell flows, even for the zero-bandwidth direction of a uni-directional connection. These same principles apply to VPCs.
VCC具有一组流量特性（即带宽参数、服务类别参数等）。VCL从其所属的VCC继承其流量特性。根据定义，VCC是双向的。然而，连接的两个方向上的业务参数可以是对称的或非对称的，即，两个方向可以具有相同或不同的业务流。通过在一个方向上分配零带宽来实现VCC上的单向业务流。注意，除了用户业务流所需的带宽之外，OAM小区流也需要带宽，即使对于单向连接的零带宽方向也是如此。这些原则同样适用于专有网络。
A Permanent Virtual Connection (PVC) is a provisioned VCC or VPC. A Switched Virtual Connection (SVC) is a switched VCC or VPC that is set up in real-time via call set-up signaling procedures. A PVC (or an SVC) can be a point-to-point, point-to-multipoint, or multipoint-to-multipoint VCC or VPC. A Soft PVC is a connection of which portions are switched, while other portions are permanent (see Figure 3 and [22]).
永久虚拟连接（PVC）是已配置的VCC或VPC。交换虚拟连接（SVC）是通过呼叫建立信令过程实时建立的交换VCC或VPC。PVC（或SVC）可以是点对点、点对多点或多点对多点VCC或VPC。软PVC是一种连接，其中部分是切换的，而其他部分是永久性的（见图3和[22]）。

In order to allocate resources fairly among different users, some networks police traffic at resource access points. The traffic enforcement or policing taken at a UNI is called Usage Parameter Control (UPC) and is conceptually activated on an incoming VCL or VPL as shown in Figure 4. The use of the traffic enforcer at the ingress of the connection is to make sure that the user traffic does not exceed the negotiated traffic parameters such as the peak cell rate associated with a specific traffic descriptor type.
为了在不同的用户之间公平地分配资源，一些网络在资源接入点监控流量。在UNI采取的流量强制或监管称为使用参数控制（UPC），概念上在传入VCL或VPL上激活，如图4所示。在连接入口处使用流量强制器是为了确保用户流量不超过协商的流量参数，例如与特定流量描述符类型相关联的峰值小区速率。

In addition, traffic shaping may be performed on an outgoing VPL or VCL at a given ATM interface. The function of the ATM traffic shaper, conceptually either at the source or an egress point of the connection, is to smooth the outgoing cell traffic inter-arrival time. If policing or shaping is not performed then the policing or shaping algorithm is not activated.
此外，可以在给定ATM接口处对传出VPL或VCL执行业务整形。ATM流量整形器的功能，从概念上讲，在连接的源或出口点，是平滑出站信元流量到达时间。如果未执行策略或成形，则不会激活策略或成形算法。
To prioritize traffic during resource congestion, ATM cells are assigned one of the two types of Cell Loss Priority (CLP), CLP=0 and CLP=1. ATM cells with CLP=0 have a higher priority in regard to cell loss than ATM cells with CLP=1. Therefore, during resource congestions, CLP=1 cells are dropped before any CLP=0 cell is dropped.
为了在资源拥塞期间对流量进行优先级排序，ATM信元被分配两种信元丢失优先级（CLP）中的一种，CLP=0和CLP=1。CLP=0的ATM信元在信元丢失方面的优先级高于CLP=1的ATM信元。因此，在资源拥塞期间，在丢弃任何CLP=0单元之前，先丢弃CLP=1单元。
RFC1695 specified that one of a number of Quality of Service (QoS) classes is assigned to a VCC or VPC by associating the object atmTrafficQoSClass with each VCL or VPL. However, new insights in ATM traffic management have caused this object to be deprecated.
RFC1695规定，通过将对象atmTrafficQoSClass与每个VCL或VPL关联，将多个服务质量（QoS）类别中的一个分配给VCC或VPC。然而，ATM流量管理方面的新见解导致该对象被弃用。
Replacing QoS Class, VPLs and VCLs are qualified in terms of their service category (atmServiceCategory). When properly configured, VCLs (or VPLs) concatenated to form a VCC (or VPC) will all have the same service category class as that of the VCC (or VPC).
VPL和VCL取代QoS等级，根据其服务类别（atmServiceCategory）进行鉴定。正确配置后，连接形成VCC（或VPC）的VCL（或VPL）都将具有与VCC（或VPC）相同的服务类别。
A manager may wish to configure the maximum number of VPI and VCI bits that can be used to identify VPIs and VCIs on a given ATM interface. This value can be less than or equal to the maximum number of bits supported by the interface hardware, and is referred to in the MIB as the Max Active VPI Bits and Max Active VCI Bits.
管理者可能希望配置可用于识别给定ATM接口上VPI和VCI的最大VPI和VCI位数。该值可以小于或等于接口硬件支持的最大位数，在MIB中称为最大活动VPI位和最大活动VCI位。
However, a manager may not be able to configure the Max Active Bits on both ends of an ATM link. For example, the manager may not be allowed write access to the peer's MIB, or there may be hardware limitations on the peer device. Therefore, the two ATM devices may use ILMI to negotiate "Max Current" VPI and VCI bits, which is the maximum number of bits that both interfaces are willing to support. This is illustrated in Figure 5. The relationship between the different parameters is illustrated in Figure 6. Note that if ILMI negotiation is not supported, then the devices have no choice but to use the configured Max Active bits, and assume that it has been configured to the same value on both ends of the link.
但是，管理器可能无法配置ATM链路两端的最大活动位。例如，可能不允许管理器对对等设备的MIB进行写访问，或者对等设备上可能存在硬件限制。因此，两个ATM设备可以使用ILMI协商“最大电流”VPI和VCI位，这是两个接口愿意支持的最大位数。这如图5所示。不同参数之间的关系如图6所示。请注意，如果不支持ILMI协商，则设备别无选择，只能使用已配置的最大活动位，并假设已在链路两端将其配置为相同的值。

| Device |--------------| Device |--------------| Device |
+--------+ +--------+ +--------+
IF a: Max Active VPI Bits = 6 (configured) Max Current VPI Bits = 6 (negotiated)
如果：最大活动VPI位=6（已配置）最大当前VPI位=6（协商）
IF b: Max Active VPI Bits = 8 (configured) Max Current VPI Bits = 6 (negotiated)
如果b：最大活动VPI位=8（已配置）最大当前VPI位=6（协商）
IF c: Max Active VPI Bits = 8 (configured) Max Current VPI Bits = 8 (negotiated)
如果c：最大活动VPI位=8（已配置）最大当前VPI位=8（协商）
IF d: Max Active VPI Bits = 8 (configured) Max Current VPI Bits = 8 (negotiated)
如果d：最大活动VPI位=8（已配置）最大当前VPI位=8（协商）
(between IF a and IF b, the minimum of the two configured "Max Active VPI Bits" is 6, so both interfaces set their "Max Current VPI Bits" to 6. Since IF c and IF d both are configured with "Max Active VPI Bits" of 8, they set their "Max Current VPI Bits" to 8.)
（在IF a和IF b之间，两个配置的“最大活动VPI位”中的最小值为6，因此两个接口都将其“最大当前VPI位”设置为6。因为IF c和IF d都配置了8的“最大活动VPI位”，所以它们将其“最大当前VPI位”设置为8。）

ATM management objects are used to manage ATM interfaces, ATM virtual links, ATM cross-connects, AAL5 entities and AAL5 connections supported by ATM hosts, ATM switches and ATM networks. This section provides an overview and background of how to use this MIB and other potential MIBs for this purpose.
ATM管理对象用于管理ATM主机、ATM交换机和ATM网络支持的ATM接口、ATM虚拟链路、ATM交叉连接、AAL5实体和AAL5连接。本节概述了如何为此目的使用此MIB和其他潜在的MIB。
The purpose of this memo is primarily to manage ATM PVCs. ATM SVCs are also represented by the management information in this MIB. However, full management of SVCs may require additional capabilities which are beyond the scope of this memo.
本备忘录的目的主要是管理ATM PVC。ATM SVC也由该MIB中的管理信息表示。但是，SVC的全面管理可能需要额外的能力，这超出了本备忘录的范围。
In addition to the MIB module defined in this memo, other MIB modules are necessary to manage ATM interfaces, links and cross-connects. Examples include MIB II for general system and interface management [16][17], the DS3 or SONET MIBs for management of physical interfaces, and, as appropriate, MIB modules for applications that make use of ATM, such as SMDS. These MIB modules are outside the scope of this specification.
除了本备忘录中定义的MIB模块外，还需要其他MIB模块来管理ATM接口、链路和交叉连接。示例包括用于一般系统和接口管理的MIB II[16][17]，用于物理接口管理的DS3或SONET MIB，以及适用于使用ATM的应用程序（如SMD）的MIB模块。这些MIB模块不在本规范的范围内。
The current specification of this ATM MIB is based on SNMPv2-SMI.
此ATM MIB的当前规范基于SNMPv2 SMI。
The managed ATM objects are arranged into the following tables:
受管ATM对象排列在下表中：
(1) ATM interface configuration table (2) ATM interface DS3 PLCP and TC sublayer tables (3) ATM traffic parameter table (4) ATM interface virtual link (VPL/VCL) configuration tables (5) ATM VP/VC cross-connect tables (6) AAL5 connection performance statistics table
(1) ATM接口配置表（2）ATM接口DS3 PLCP和TC子层表（3）ATM业务参数表（4）ATM接口虚拟链路（VPL/VCL）配置表（5）ATM VP/VC交叉连接表（6）AAL5连接性能统计表
Note that, managed objects for activation/deactivation of OAM cell flows and ATM traps notifying virtual connection or virtual link failures are outside the scope of this memo.
请注意，用于激活/停用OAM信元流和通知虚拟连接或虚拟链路故障的ATM陷阱的托管对象不在本备忘录的范围内。
This table contains information on ATM cell layer configuration of local ATM interfaces on an ATM device in addition to the information on such interfaces contained in the ifTable.
此表包含ATM设备上本地ATM接口的ATM信元层配置信息，以及ifTable中包含的此类接口信息。
These tables provide performance statistics of the DS3 PLCP and TC sublayer of local ATM interfaces on a managed ATM device. DS3 PLCP and TC sublayer are currently used to carry ATM cells respectively over DS3 and SONET transmission paths.
这些表提供了受管ATM设备上本地ATM接口的DS3 PLCP和TC子层的性能统计信息。DS3 PLCP和TC子层目前分别用于在DS3和SONET传输路径上承载ATM信元。
ATM virtual link and cross-connect tables model bi-directional ATM virtual links and ATM cross-connects. The ATM VP/VC link tables are implemented in an ATM host, ATM switch and ATM network. The ATM switch and ATM network also implement the ATM VP/VC cross-connect tables. Both link and cross-connect tables are implemented in a carrier's network for Customer Network Management (CNM) purposes.
ATM虚拟链路和交叉连接表为双向ATM虚拟链路和ATM交叉连接建模。ATM VP/VC链路表在ATM主机、ATM交换机和ATM网络中实现。ATM交换机和ATM网络还实现了ATM VP/VC交叉连接表。出于客户网络管理（CNM）的目的，链路和交叉连接表都在运营商的网络中实现。
The ATM virtual link tables are used to create, delete or modify ATM virtual links in an ATM host, ATM switch and ATM network. ATM virtual link tables along with the cross-connect tables are used to create, delete or modify ATM cross-connects in an ATM switch or ATM network (e.g., for CNM purposes).
ATM虚拟链路表用于创建、删除或修改ATM主机、ATM交换机和ATM网络中的ATM虚拟链路。ATM虚拟链路表和交叉连接表用于创建、删除或修改ATM交换机或ATM网络中的ATM交叉连接（例如，用于CNM目的）。
For a PVC, the cross-connect between two VPLs is represented in the atmVpCrossConnectTable of the ATM-MIB, indexed by the atmVplCrossConnectIdentifier values for the two VPLs, and the cross-
对于PVC，两个VPL之间的交叉连接在ATM-MIB的atmVpCrossConnectTable中表示，由两个VPL的ATMVPLCrossConnectionIdentifier值和交叉连接索引-
rconnect between two VCLs is represented in the atmVcCrossConnectTable of the ATM-MIB, indexed by the atmVclCrossConnectIdentifier values for the two VCLs.

For the purposes of the sysServices object in the System Group of MIB II [16], ATM is a data link layer protocol. Thus, for ATM switches and ATM networks, sysServices will have the value "2".
就MIB II[16]系统组中的sysServices对象而言，ATM是一种数据链路层协议。因此，对于ATM交换机和ATM网络，sysServices的值为“2”。
The Interfaces Group of MIB II defines generic managed objects for managing interfaces. This memo contains the media-specific extensions to the Interfaces Group for managing ATM interfaces.
MIB II的接口组定义了用于管理接口的通用托管对象。此备忘录包含接口组的媒体特定扩展，用于管理ATM接口。
This memo assumes the interpretation of the Interfaces Group to be in accordance with [17] which states that the interfaces table (ifTable) contains information on the managed resource's interfaces and that each sub-layer below the internetwork layer of a network interface is considered an interface. Thus, the ATM cell layer interface is represented as an entry in the ifTable. This entry is concerned with the ATM cell layer as a whole, and not with individual virtual connections which are managed via the ATM-specific managed objects specified in this memo. The inter-relation of entries in the ifTable is defined by Interfaces Stack Group defined in [17].
本备忘录假设接口组的解释符合[17]，其中说明接口表（ifTable）包含有关受管资源接口的信息，并且网络接口的网络层下的每个子层都被视为接口。因此，ATM信元层接口被表示为ifTable中的一个条目。此条目涉及ATM信元层作为一个整体，而不是通过本备忘录中指定的ATM特定托管对象管理的单个虚拟连接。ifTable中条目的相互关系由[17]中定义的接口堆栈组定义。
Some specific interpretations of ifTable for the ATM cell layer follow.
下面将对ATM信元层的ifTable进行一些具体解释。
Object Use for the generic ATM layer
====== =============================
Object Use for the generic ATM layer

ifIndex Each ATM port is represented by an ifEntry.
ifIndex每个ATM端口由一个ifEntry表示。
ifDescr Description of the ATM interface.
ATM接口的ifDescr描述。
ifType The value that is allocated for ATM is 37.
如果键入，则分配给ATM的值为37。
ifSpeed The total bandwidth in bits per second for use by the ATM layer.
ifSpeed ATM层使用的总带宽（以比特/秒为单位）。
ifPhysAddress The interface's address at the ATM protocol sublayer; the ATM address which would be used as the value of the Called Party Address Information Element (IE) of a signalling message for a connection which either: - would terminate at this interface, or - for which the Called Party Address IE would need to be replaced by the Called Party SubAddress IE before the message was forwarded to any other interface. For an interface on which signalling is not supported, then the interface does not necessarily have an address, but if it does, then ifPhysAddress is the address which would be used as above in the event that signalling were supported. If the interface has multiple such addresses, then ifPhysAddress is its primary address. If the interface has no addresses, then ifPhysAddress is an octet string of zero length. Address encoding is as per [20]. Note that addresses assigned for purposes other than those listed above (e.g., an address associated with the service provider side of a public network UNI) may be represented through atmInterfaceSubscrAddress.
ifPhysAddress在ATM协议子层上显示接口地址；ATM地址，将用作信令消息的被叫方地址信息元素（IE）的值，用于以下连接：-将在该接口终止，或-在将消息转发到任何其他接口之前，需要将被叫方地址IE替换为被叫方子地址IE。对于不支持信令的接口，则该接口不一定有地址，但如果有，则ifPhysAddress是在支持信令的情况下如上所述使用的地址。如果接口有多个这样的地址，那么ifPhysAddress是它的主地址。如果接口没有地址，那么ifPhysAddress是长度为零的八位字节字符串。地址编码按照[20]进行。注意，为上述目的以外的目的分配的地址（例如，与公共网络UNI的服务提供商侧相关联的地址）可以通过atmInterfaceSubscrAddress表示。
ifAdminStatus See [17].

Support of AAL5 managed objects in an ATM switch and ATM host are described below.
ATM交换机和ATM主机中对AAL5托管对象的支持如下所述。
Managing AAL5 in a switch involves:
在交换机中管理AAL5包括：
(1) performance management of an AAL5 entity as an internal resource in a switch
(1) 作为交换机内部资源的AAL5实体的性能管理
(2) performance management of AAL5 per virtual connection
(2) 每个虚拟连接的AAL5性能管理
AAL5 in a switch is modeled as shown in Figure 7 and 8. AAL5 will be managed in a switch for only those virtual connections that carry AAL5 and are terminated at the AAL5 entity in the switch. Note that, the virtual channels within the ATM UNIs carrying AAL5 will be switched by the ATM switching fabric (termed as ATM Entity in the figure) to the virtual channels on a proprietary internal interface associated with the AAL5 process (termed as AAL5 Entity in the figure). Therefore, performance management of the AAL5 resource in the switch will be modeled using the ifTable through an internal (pseudo-ATM) virtual interface and the AAL5 performance management per virtual connection will be supported using an additional AAL5 connection table in the ATM MIB. The association between the AAL5 virtual link at the proprietary virtual, internal interface and the ATM virtual link at the ATM interface will be derived from the virtual channel cross-connect table and the virtual channel link table in the ATM MIB. Note that for the proprietary virtual interface the traffic transmit and receive conventions in the virtual channel link table are as follows:
交换机中的AAL5建模如图7和图8所示。AAL5将在交换机中进行管理，仅用于承载AAL5并在交换机中的AAL5实体处终止的虚拟连接。注意，承载AAL5的ATM UNIs内的虚拟信道将由ATM交换结构（图中称为ATM实体）交换到与AAL5进程（图中称为AAL5实体）相关联的专有内部接口上的虚拟信道。因此，交换机中AAL5资源的性能管理将通过内部（伪ATM）虚拟接口使用ifTable进行建模，每个虚拟连接的AAL5性能管理将通过ATM MIB中的附加AAL5连接表得到支持。专有虚拟内部接口处的AAL5虚拟链路与ATM接口处的ATM虚拟链路之间的关联将从ATM MIB中的虚拟信道交叉连接表和虚拟信道链路表中导出。请注意，对于专有虚拟接口，虚拟信道链路表中的流量传输和接收约定如下：
Transmitting traffic: ATM Entity ---> AAL5 Entity
Receiving traffic: ATM Entity <--- AAL5 Entity
Transmitting traffic: ATM Entity ---> AAL5 Entity
Receiving traffic: ATM Entity <--- AAL5 Entity

The ILMI MIBs are specified by the ATM Forum as a set of several MIBs, all currently defined in the ILMI Specification [23]. The ILMI protocols and MIBs allow two connected ATM Interface Management Entities (IMEs) to exchange bi-directional parameters, mainly to facilitate auto-configuration between ATM peer entities. The support of the ATM management functions by the ILMI MIBs and those contained in this memo are compared in Table 1. In this table, "yes" in the "ILMI MIBs" column indicates that the management functions are supported by the ILMI MIBs. The parenthesized numbers in the "This memo" column correspond to the sets of tables enumerated in Section 6.2.
ATM论坛将ILMI MIB指定为多个MIB的集合，所有MIB目前都在ILMI规范中定义[23]。ILMI协议和MIB允许两个连接的ATM接口管理实体（IME）交换双向参数，主要用于促进ATM对等实体之间的自动配置。表1比较了ILMI MIB对ATM管理功能的支持和本备忘录中包含的功能。在此表中，“ILMI MIB”列中的“是”表示ILMI MIB支持管理功能。“本备忘录”列中括号内的数字对应于第6.2节中列举的表格集。
For that subset of management information which the ILMI MIBs and this memo have in common, every effort has been made to retain identical semantics and syntax, even though the MIB objects are identified using different OBJECT IDENTIFIERs.
对于ILMI MIB和本备忘录共有的管理信息子集，已尽一切努力保留相同的语义和语法，即使MIB对象使用不同的对象标识符标识。

Negotiated VPL establishment
协商建立VPL
(1) The management application creates a VPL entry in the atmVplTable by setting atmVplRowStatus to createAndWait(5). This may fail for the following reasons: - The selected VPI value is unavailable, - The selected VPI value is in use. Otherwise, the agent creates a row and reserves the VPI value on that port.
(1) 管理应用程序通过将atmVplRowStatus设置为createAndWait（5），在atmVplTable中创建一个VPL条目。由于以下原因，此操作可能失败：-选定的VPI值不可用，-选定的VPI值正在使用。否则，代理将创建一行并在该端口上保留VPI值。
(2) The manager selects an existing row(s) in the atmTrafficDescrParamTable, thereby, selecting a set of self-consistent ATM traffic parameters and the service category for receive and transmit directions of the VPL.
(2) 管理器选择atmTrafficDescrParamTable中的现有行，从而为VPL的接收和发送方向选择一组自一致的ATM流量参数和服务类别。
(2a) If no suitable row(s) in the atmTrafficDescrParamTable exists, the manager must create a new row(s) in that table.
（2a）如果ATMTrafficDescrParam表中不存在合适的行，经理必须在该表中创建新行。
(2b) The manager characterizes the VPL's traffic parameters through setting the atmVplReceiveTrafficDescrIndex and the
（2b）管理器通过设置ATMVPLReceiveTrafficDescriptix和
atmVplTransmitTrafficDescrIndex values in the VPL table, which point to the rows containing desired ATM traffic parameter values in the atmTrafficDescrParamTable. The agent will check the availability of resources and may refuse the request. If the transmit and receive service categories are inconsistent, the agent should refuse the request.
VPL表中的ATMVPLTransmittTrafficDescriptix值，该值指向包含atmTrafficDescrParamTable中所需ATM流量参数值的行。代理将检查资源的可用性，并可能拒绝该请求。如果发送和接收服务类别不一致，则代理应拒绝该请求。
(3) The manager activates the VPL by setting the the atmVplRowStatus to active(1). If this set is successful, the agent has reserved the resources to satisfy the requested traffic parameter values and the service category for that VPL.
(3) 管理器通过将atmVplRowStatus设置为active（1）来激活VPL。如果此设置成功，则代理已保留资源以满足该VPL的请求流量参数值和服务类别。
(4) If the VPL terminates a VPC in the ATM host or switch, the manager turns on the atmVplAdminStatus to up(1) to turn the VPL traffic flow on. Otherwise, the atmVpCrossConnectTable must be used to cross-connect the VPL to another VPL(s) in an ATM switch or network.
(4) 如果VPL终止ATM主机或交换机中的VPC，则管理器将atmVplAdminStatus打开到up（1），以打开VPL流量。否则，必须使用atmVpCrossConnectTable将VPL交叉连接到ATM交换机或网络中的另一个VPL。
One-Shot VPL Establishment
一次性VPL建立
A VPL may also be established in one step by a set-request with all necessary VPL parameter values and atmVplRowStatus set to createAndGo(4).
VPL也可以通过一个set请求在一个步骤中建立，该请求具有所有必要的VPL参数值，并且atmVplRowStatus设置为createAndGo（4）。
In contrast to the negotiated VPL establishment which allows for detailed error checking (i.e., set errors are explicitly linked to particular resource acquisition failures), the one-shot VPL establishment performs the setup on one operation but does not have the advantage of step-wise error checking.
与允许详细错误检查的协商VPL建立（即，设置错误与特定资源获取故障明确关联）不同，一次性VPL建立在一次操作上执行设置，但不具有逐步错误检查的优点。

atmVclEntry对象类型语法atmVclEntry MAX-ACCESS不可访问状态当前描述“VCL表中的一个条目。此条目用于对双向VCL建模。要在ATM接口上创建VCL，请使用以下任一过程：
Negotiated VCL establishment
协商设立VCL
(1) The management application creates a VCL entry in the atmVclTable by setting atmVclRowStatus to createAndWait(5). This may fail for the following reasons: - The selected VPI/VCI values are unavailable, - The selected VPI/VCI values are in use. Otherwise, the agent creates a row and reserves the VPI/VCI values on that port.
(1) 管理应用程序通过将atmVclRowStatus设置为createAndWait（5），在atmVclTable中创建VCL条目。由于以下原因，此操作可能失败：-选定的VPI/VCI值不可用，-选定的VPI/VCI值正在使用。否则，代理将创建一行并在该端口上保留VPI/VCI值。
(2) The manager selects an existing row(s) in the atmTrafficDescrParamTable, thereby, selecting a set of self-consistent ATM traffic parameters and the service category for receive and transmit directions of the VCL.
(2) 管理器选择atmTrafficDescrParamTable中的现有行，从而为VCL的接收和发送方向选择一组自一致的ATM流量参数和服务类别。
(2a) If no suitable row(s) in the atmTrafficDescrParamTable exists, the manager must create a new row(s) in that table.
（2a）如果ATMTrafficDescrParam表中不存在合适的行，经理必须在该表中创建新行。
(2b) The manager characterizes the VCL's traffic parameters through setting the atmVclReceiveTrafficDescrIndex and the atmVclTransmitTrafficDescrIndex values in the VCL table, which point to the rows containing desired ATM traffic parameter values in the atmTrafficDescrParamTable. The agent will check the availability of resources and may refuse the request. If the transmit and receive service categories are inconsistent, the agent should refuse the request.
（2b）管理器通过设置VCL表中的ATMVCLReceiveTrafficDescriptix和ATMVCLTransmitTrafficDescriptix值来表征VCL的流量参数，这些值指向ATMTTrafficDescrpParamTable中包含所需ATM流量参数值的行。代理将检查资源的可用性，并可能拒绝该请求。如果发送和接收服务类别不一致，则代理应拒绝该请求。
(3) The manager activates the VCL by setting the the atmVclRowStatus to active(1) (for requirements on this activation see the description of atmVclRowStatus). If this set is successful, the agent has reserved the resources to satisfy the requested traffic parameter values and the service category for that VCL. (4) If the VCL terminates a VCC in the ATM host or switch, the manager turns on the atmVclAdminStatus to up(1) to turn the VCL traffic flow on. Otherwise, the atmVcCrossConnectTable must be used to cross-connect the VCL to another VCL(s) in an ATM switch or network.
(3) 管理器通过将atmVclRowStatus设置为激活（1）来激活VCL（有关此激活的要求，请参阅atmVclRowStatus的说明）。如果此设置成功，则代理已保留资源以满足该VCL的请求流量参数值和服务类别。（4） 如果VCL终止ATM主机或交换机中的VCC，则管理器将atmVclAdminStatus打开到up（1）以打开VCL流量。否则，必须使用ATMVCCrossConnectable将VCL交叉连接到ATM交换机或网络中的另一个VCL。
One-Shot VCL Establishment
一次性VCL建立
A VCL may also be established in one step by a set-request with all necessary VCL parameter values and atmVclRowStatus set to createAndGo(4).
VCL也可以通过一个set请求在一个步骤中建立，该请求具有所有必要的VCL参数值，并且atmVclRowStatus设置为createAndGo（4）。
In contrast to the negotiated VCL establishment which allows for detailed error checking (i.e., set errors are explicitly linked to particular resource acquisition failures), the one-shot VCL establishment performs the setup on one operation but does not have the advantage of step-wise error checking.
与允许详细错误检查的协商VCL建立（即，设置错误与特定资源获取故障明确关联）不同，一次性VCL建立在一次操作上执行设置，但不具有逐级错误检查的优点。

Step-wise Procedures to set up a VP Cross-connect
设置VP交叉连接的分步程序
Once the entries in the atmVplTable are created, the following procedures are used to cross-connect the VPLs together.
创建atmVplTable中的条目后，使用以下步骤将VPL交叉连接在一起。
(1) The manager obtains a unique atmVpCrossConnectIndex by reading the atmVpCrossConnectIndexNext object.
(1) 管理器通过读取atmVpCrossConnectIndex NEXT对象获得唯一的atmVpCrossConnectIndex。
(2) Next, the manager creates a set of one or more rows in the ATM VP Cross Connect Table, one for each cross-connection between two VPLs. Each row is indexed by the ATM interface port numbers and VPI values of the two ends of that cross-connection. This set of rows specifies the topology of the VPC cross-connect and is identified by a single value of atmVpCrossConnectIndex.
(2) 接下来，管理器在ATM VP交叉连接表中创建一组一行或多行，两个VPL之间的每个交叉连接一行。每一行都由该交叉连接两端的ATM接口端口号和VPI值索引。这组行指定VPC交叉连接的拓扑结构，并由单个值atmVpCrossConnectIndex标识。
Negotiated VP Cross-Connect Establishment
协商VP交叉连接建立
(2a) The manager creates a row in this table by setting atmVpCrossConnectRowStatus to createAndWait(5). The agent checks the requested topology and the mutual sanity of the ATM traffic parameters and service categories, i.e., the row creation fails if: - the requested topology is incompatible with associated values of atmVplCastType, - the requested topology is not supported by the agent, - the traffic/service category parameter values associated with the requested row are incompatible with those of already existing rows for this VP cross-connect. [For example, for setting up a point-to-point VP cross-connect, the ATM traffic parameters in the receive direction
（2a）管理器通过将atmVpCrossConnectRowStatus设置为createAndWait（5），在此表中创建一行。代理检查请求的拓扑以及ATM流量参数和服务类别的相互健全性，即，如果：-请求的拓扑与atmVplCastType的关联值不兼容，-代理不支持请求的拓扑，则行创建失败，-与请求行关联的流量/服务类别参数值与此VP交叉连接的现有行的参数值不兼容。[例如，为了建立点对点VP交叉连接，接收方向上的ATM流量参数
of a VPL at the low end of the cross-connect must equal to the traffic parameters in the transmit direction of the other VPL at the high end of the cross-connect, otherwise, the row creation fails.] The agent also checks for internal errors in building the cross-connect.
交叉连接低端的一个VPL的流量必须等于交叉连接高端的另一个VPL传输方向上的流量参数，否则，行创建失败。]代理还检查建立交叉连接时的内部错误。
The atmVpCrossConnectIndex values in the corresponding atmVplTable rows are filled in by the agent at this point.
此时代理将填写相应atmVplTable行中的ATMVPCrossConnectionIndex值。
(2b) The manager promotes the row in the atmVpCrossConnectTable by setting atmVpCrossConnectRowStatus to active(1). If this set is successful, the agent has reserved the resources specified by the ATM traffic parameter and Service category values for each direction of the VP cross-connect in an ATM switch or network.
（2b）管理器通过将atmVpCrossConnectRowStatus设置为active（1），提升atmVpCrossConnectTable中的行。如果此设置成功，则代理已为ATM交换机或网络中VP交叉连接的每个方向保留由ATM流量参数和服务类别值指定的资源。
(3) The manager sets the atmVpCrossConnectAdminStatus to up(1) in all rows of this VP cross-connect to turn the traffic flow on.
(3) 管理器在此VP交叉连接的所有行中将atmVpCrossConnectAdminStatus设置为up（1），以打开交通流。
One-Shot VP Cross-Connect Establishment
一次性VP交叉连接建立
A VP cross-connect may also be established in one step by a set-request with all necessary parameter values and atmVpCrossConnectRowStatus set to createAndGo(4).
VP交叉连接也可以通过设置请求一步建立，该请求具有所有必要的参数值，并且atmVpCrossConnectRowStatus设置为createAndGo（4）。
In contrast to the negotiated VP cross-connect establishment which allows for detailed error checking (i.e., set errors are explicitly linked to particular resource acquisition failures), the one-shot VP cross-connect establishment performs the setup on one operation but does not have the advantage of step-wise error checking.
与协商VP交叉连接建立相比，协商VP交叉连接建立允许详细的错误检查（即，设置错误明确链接到特定的资源获取故障），一次性VP交叉连接建立在一次操作上执行设置，但不具有逐步错误检查的优点。

Step-wise Procedures to set up a VC Cross-connect
逐步建立VC交叉连接的程序
Once the entries in the atmVclTable are created, the following procedures are used to cross-connect the VCLs together to form a VCC segment.
创建atmVclTable中的条目后，使用以下步骤将VCL交叉连接在一起，形成VCC段。
(1) The manager obtains a unique atmVcCrossConnectIndex by reading the atmVcCrossConnectIndexNext object.
(1) 管理器通过读取atmVcCrossConnectIndex NEXT对象获得唯一的atmVcCrossConnectIndex。
(2) Next, the manager creates a set of one or more rows in the ATM VC Cross Connect Table, one for each cross-connection between two VCLs. Each row is indexed by the ATM interface port numbers and VPI/VCI values of the two ends of that cross-connection. This set of rows specifies the topology of the VCC cross-connect and is identified by a single value of atmVcCrossConnectIndex.
(2) 接下来，管理器在ATM VC交叉连接表中创建一组一行或多行，两个VCL之间的每个交叉连接一行。每一行由该交叉连接两端的ATM接口端口号和VPI/VCI值索引。这组行指定VCC交叉连接的拓扑，并由单个值atmVcCrossConnectIndex标识。
Negotiated VC Cross-Connect Establishment
协商建立交叉连接
(2a) The manager creates a row in this table by setting atmVcCrossConnectRowStatus to createAndWait(5). The agent checks the requested topology and the mutual sanity of the ATM traffic parameters and service categories, i.e., the row creation fails if: - the requested topology is incompatible with associated values of atmVclCastType, - the requested topology is not supported by the agent, - the traffic/service category parameter values associated with the requested row are incompatible with those of already existing rows for this VC cross-connect. [For example, for setting up a point-to-point VC cross-connect, the ATM traffic parameters in the receive direction of a VCL at the low end of the cross-connect must equal to the traffic parameters in the transmit direction of the other VCL at the high end of the cross-connect, otherwise, the row creation fails.] The agent also checks for internal errors in building the cross-connect.
（2a）管理器通过将atmVcCrossConnectRowStatus设置为createAndWait（5），在此表中创建一行。代理检查请求的拓扑以及ATM流量参数和服务类别的相互健全性，即，如果：-请求的拓扑与atmVclCastType的关联值不兼容，-代理不支持请求的拓扑，则行创建失败，-与请求行关联的流量/服务类别参数值与此VC交叉连接的现有行的值不兼容。[例如，为了建立点对点VC交叉连接，交叉连接低端VCL接收方向上的ATM流量参数必须等于交叉连接高端另一VCL传输方向上的流量参数，否则，行创建失败。]代理还检查构建交叉连接时是否存在内部错误。
The atmVcCrossConnectIndex values in the
中的ATMVCCrossConnectionIndex值
corresponding atmVclTable rows are filled in by the agent at this point.
此时代理将填写相应的atmVclTable行。
(2b) The manager promotes the row in the atmVcCrossConnectTable by setting atmVcCrossConnectRowStatus to active(1). If this set is successful, the agent has reserved the resources specified by the ATM traffic parameter and Service category values for each direction of the VC cross-connect in an ATM switch or network.
（2b）管理器通过将atmVcCrossConnectRowStatus设置为active（1），提升ATMVCCrossConnectRowTable中的行。如果此设置成功，则代理已为ATM交换机或网络中VC交叉连接的每个方向保留由ATM流量参数和服务类别值指定的资源。
(3) The manager sets the atmVcCrossConnectAdminStatus to up(1) in all rows of this VC cross-connect to turn the traffic flow on.
(3) 管理器在此VC交叉连接的所有行中将atmVcCrossConnectAdminStatus设置为up（1），以打开交通流。
One-Shot VC Cross-Connect Establishment
一次性VC交叉连接建立
A VC cross-connect may also be established in one step by a set-request with all necessary parameter values and atmVcCrossConnectRowStatus set to createAndGo(4).
VC交叉连接也可以通过设置请求一步建立，该请求具有所有必要的参数值，并且atmVcCrossConnectRowStatus设置为createAndGo（4）。
In contrast to the negotiated VC cross-connect establishment which allows for detailed error checking i.e., set errors are explicitly linked to particular resource acquisition failures), the one-shot VC cross-connect establishment performs the setup on one operation but does not have the advantage of step-wise error checking.

(2) After deletion of the appropriate atmVcCrossConnectEntries, the manager may set atmVclRowStatus to destroy(6) the associated VCLs. The agent releases the resources and removes the associated rows in the atmVclTable.

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。
The managed objects in this MIB contain sensitive information since, collectively, they allow tracing and influencing of virtual connections in ATM switches or networks and provide information of their traffic characteristics.
此MIB中的受管对象包含敏感信息，因为它们共同允许跟踪和影响ATM交换机或网络中的虚拟连接，并提供其流量特性的信息。
It is thus important to control even GET access to these objects and possibly to even encrypt the values of these object when sending them over the network via SNMP. Not all versions of SNMP provide features for such a secure environment.
因此，在通过SNMP通过网络发送这些对象时，控制甚至访问这些对象，甚至可能加密这些对象的值，这一点非常重要。并非所有版本的SNMP都为这种安全环境提供功能。
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 2274 [12] and the View-based Access Control Model RFC 2275 [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RFC 2274[12]和基于视图的访问控制模型RFC 2275[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.
