Abstract
摘要
This document describes the set of Remote Authentication Dial-In User Service Vendor-Specific Attributes (RADIUS VSAs) defined by the DSL Forum.
本文档描述了DSL论坛定义的一组远程身份验证拨入用户服务供应商特定属性（RADIUS VSA）。
These attributes are designed to transport Digital Subscriber Line (DSL) information that is not supported by the standard RADIUS attribute set. It is expected that this document will be updated if and when the DSL Forum defines additional vendor-specific attributes, since its primary purpose is to provide a reference for DSL equipment vendors wishing to interoperate with other vendors' products.
这些属性用于传输标准RADIUS属性集不支持的数字用户线（DSL）信息。如果DSL论坛定义了其他特定于供应商的属性，预计本文件将更新，因为其主要目的是为希望与其他供应商的产品进行互操作的DSL设备供应商提供参考。

The DSL Forum has created additional RADIUS [RFC2865] [RFC2866] vendor-specific attributes to carry DSL line identification and characterization information. This information is forwarded from the Access Node/DSLAM to the BRAS via Vendor-Specific PPPoE Tags [RFC2516], DHCP Relay Options [RFC3046], and Vendor-Specific Information Suboptions [RFC4243]. This document describes the subscriber line identification and characterization information and its mapping to RADIUS VSAs by the BRAS.
DSL论坛创建了额外的RADIUS[RFC2865][RFC2866]供应商特定属性，以携带DSL线路标识和特征信息。该信息通过特定于供应商的PPPoE标签[RFC2516]、DHCP中继选项[RFC3046]和特定于供应商的信息子选项[RFC4243]从接入节点/DSLAM转发到BRAS。本文件描述了用户线路标识和特征信息，以及BRAS将其映射到RADIUS VSA。
The information acquired may be used to provide authentication and accounting functionality. It may also be collected and used for management and troubleshooting purposes.

String
一串
The String field contains information about the Access-Node to which the subscriber is attached, along with an identifier for the subscriber's DSL port on that Access-Node.
字符串字段包含有关订阅者连接到的接入节点的信息，以及该接入节点上订阅者的DSL端口的标识符。
The exact syntax of the string is implementation dependent; however, a typical practice is to subdivide it into two or more space-separated components, one to identify the Access-Node and another the subscriber line on that node, with perhaps an indication of whether that line is Ethernet or ATM. Example formats for this string are shown below.
字符串的确切语法取决于实现；然而，典型的做法是将其细分为两个或多个空间分隔的组件，一个用于标识接入节点，另一个用于标识该节点上的用户线路，并可能指示该线路是以太网还是ATM。此字符串的示例格式如下所示。
"Access-Node-Identifier atm slot/port:vpi.vci" (when ATM/DSL is used)
“接入节点标识符atm插槽/端口：vpi.vci”（使用atm/DSL时）
"Access-Node-Identifier eth slot/port[:vlan-id]" (when Ethernet/DSL is used)
“访问节点标识符eth插槽/端口[：vlan id]”（使用以太网/DSL时）
An example showing the slot and port field encoding is given below:
下面给出了显示插槽和端口字段编码的示例：
"[Relay-identifier] atm 3/0:100.33"
(slot = 3, port = 0, vpi = 100, vci = 33)
"[Relay-identifier] atm 3/0:100.33"
(slot = 3, port = 0, vpi = 100, vci = 33)
The Access-Node-Identifier is a unique ASCII string that does not include 'space' characters. The syntax of the slot and port fields reflects typical practices currently in place. The slot identifier does not exceed 6 characters in length, and the port identifier does not exceed 3 characters in length using a '\' as a delimiter.
访问节点标识符是不包含“空格”字符的唯一ASCII字符串。插槽和端口字段的语法反映了当前的典型实践。插槽标识符的长度不超过6个字符，使用“\”作为分隔符的端口标识符的长度不超过3个字符。
The exact manner in which slots are identified is Access Node/DSLAM implementation dependent. The vpi, vci, and vlan-id fields (when applicable) are related to a given access loop (U-interface).
标识插槽的确切方式取决于接入节点/DSLAM实现。vpi、vci和vlan id字段（如果适用）与给定的访问环路（U接口）相关。
Description
描述
The Agent-Remote-Id Attribute contains an operator-specific, statically configured string that uniquely identifies the subscriber on the associated access loop of the Access Node/DSLAM.
Agent Remote Id属性包含一个特定于操作员的静态配置字符串，该字符串唯一标识接入节点/DSLAM的关联接入环路上的订户。
In a typical subscriber environment, multiple attributes can be used to identify the user, among others: Username (for example, as defined on a PPP client); Agent-Circuit-Id (a static, pre-defined string sent from the Access Node/DSLAM); Agent-Remote-Id (an operator-defined string configured on and sent by the Access Node/DSLAM).
在典型的订户环境中，可以使用多个属性来标识用户，除其他外：用户名（例如，在PPP客户端上定义的用户名）；代理电路Id（从接入节点/DSLAM发送的静态预定义字符串）；代理远程Id（在接入节点/DSLAM上配置并由其发送的操作员定义的字符串）。
This Attribute MAY be included in both Access-Request and Accounting-Request packets.
该属性可以包含在访问请求和记帐请求数据包中。

The security of these Attributes relies on an implied trust relationship between the Access Node/DSLAM and the BRAS. The identifiers that are inserted by the Access Node/DSLAM are unconditionally trusted; the BRAS does not perform any validity check on the information received. These Attributes are intended to be used in environments in which the network infrastructure (the Access Node/DSLAM, the BRAS, and the entire network in which those two devices reside) is trusted and secure.
这些属性的安全性依赖于接入节点/DSLAM和BRA之间的隐含信任关系。接入节点/DSLAM插入的标识符是无条件信任的；BRAS不对收到的信息进行任何有效性检查。这些属性旨在用于网络基础设施（接入节点/DSLAM、BRA和这两个设备所在的整个网络）受信任和安全的环境中。
As used in this document, the word "trusted" implies that unauthorized traffic cannot enter the network except through secured and trusted devices and that all devices internal to the network are secure and trusted. Careful consideration should be given to the potential security vulnerabilities that are present in this model before deploying this option in actual networks.
本文件中使用的“受信任”一词意味着未经授权的通信量只能通过安全和受信任的设备进入网络，并且网络内部的所有设备都是安全和受信任的。在实际网络中部署此选项之前，应仔细考虑此模型中存在的潜在安全漏洞。
The Attributes described in this document neither increase nor decrease the security of the RADIUS protocol. For discussions of various RADIUS vulnerabilities, see [RFC2607], [RFC3579], [RFC3162], and [RFC3580].
本文档中描述的属性既不会增加也不会降低RADIUS协议的安全性。有关各种RADIUS漏洞的讨论，请参阅[RFC2607]、[RFC3579]、[RFC3162]和[RFC3580]。
