Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

关于此翻译

思科采用人工翻译与机器翻译相结合的方式将此文档翻译成不同语言，希望全球的用户都能通过各自的语言得到支持性的内容。 请注意：即使是最好的机器翻译，其准确度也不及专业翻译人员的水平。 Cisco Systems, Inc. 对于翻译的准确性不承担任何责任，并建议您总是参考英文原始文档（已提供链接）。

    简介

    本文档介绍在呼叫控制和信令模式下以及在�思科IP传输点(ITP)上为思科公共交换电话网(PSTN)网关(PGW)2200软交换进行的流控制传输协议(SCTP)故障排除。SCTP旨在通过IP网络传输PSTN信令消息。协议在RFC 2960中定义 leavingcisco.com,RFC 3286提供了介绍性文本RFC leavingcisco.com。

    先决条件

    要求

    本文档的读者应掌握以下这些主题的相关知识：

    使用的组件

    本文档中的信息基于Cisco PGW 2200 9.4(1)及更高版本。

    本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。

    规则

    有关文件规则的更多信息请参见“ Cisco技术提示规则”。

    设计注意事项

    通常，信令系统7(SS7)网络是为特定服务等级(GOS)设计的。 对于此场景，请参阅ITU规范E.723，该规范解决了在设计SS7网络时确保端到端GOS的一些注意事项。

    ITU规范E.723文档将目标端到端初始地址消息(IAM)传输时间（单向）确定为0.9秒，并包含其他详细信息。

    通常，两个SS7-over-IP(SS7oIP)节点之间的往返时间(RTT)小于200-300毫秒，使性能很好地满足大多数上层SS7应用的要求。RTT可能超出此值，但应评估网络的总体设计，以确保多跳不会超过应用层计时器。

    排除ITP-SCTP故障

    客户端 — 服务器信令网关(SG)架构(SG是服务器；PGW 2200是客户端。)

    pgw_sctp-1.gif

    SCTP消息

    pgw_sctp-2.gif

    在ITP上，发出debug命令：

    v2650-2# debug ip sctp war 
SCTP: Turning warnings debugging on 
v2650-2# debug ip sctp signal 
SCTP: Turning signal debugging on 
v2650-2# debug ip sctp state 
SCTP: Turning state debugging on 
v2650-2# debug ip sctp init

    在PGW 2200上，一个关联已停止服务。使用人机语言(MML)命令set-association:m3ua-assoc2:IS，confirm使此关联生效，然后按照ITP上的debug发现不同状态（以粗体显示）。

    为帮助排除PGW 2200和ITP上的SCTP和消息传输部分(MTP)第3级用户适配(M3UA)问题，下面是信令流和调试的说明(随带粗体项提供)。

    注意：初学者的SCTP中介绍了信令流 leavingcisco.com。

    SCTP和M3UA错误处理

    消息类型 描述
    负载数据 包含SS7 MTP3-User协议数据，该数据是MTP-�TRANSFER基元，包括完整的MTP3路由标签。
    目标不可用(DUNA) 用于向辅助信号路径(ASP)发出信号，指示目的地不可用。类似于MTP Transfer Prohibited。
    可用目标(DAVA) 用于向ASP发出目标可用的信号。类似于允许的MTP传输。
    目标审计(DAUD) 用于从SG状态请求SS7路由的可用性或拥塞。
    SS7网络拥塞(SCON) 用于指示SG的拥塞。
    目标部件不可用(DUPU) 由SG发送，以指示远程对等MTP3用户不可用。
    目标受限(DRST) 发送到ASP，表示SS7目标受限。类似于MTP。
    ASP Up(ASPUP) 此消息用于向SG指示ASP已启动、正在运行并准备接收与维护相关的消息。
    ASP上确认 确认ASP Up消息。
    ASP关闭(ASPDN) 向SG表示ASP未准备好接收流量。
    ASP向下确认 确认ASP关闭消息。
    注册请求(REG REQ) 由ASP发送到SG，用于向SG注册路由密钥。
    注册响应 用于确认注册请求。
    取消注册请求(DEREG REQ) 用于向SG发出信号以取消注册路由密钥。
    取消注册响应(DREG RSP) 用于确认取消注册请求。
    ASP活动(ASPAC) 表示ASP现在处于活动状态并准备接受流量。
    ASP活动确认 用于确认ASP活动消息。
    ASP非活动(ASPIA) 用于指示ASP已进入非活动模式。
    ASP非活动确认 由SG发送以确认ASP处于非活动状态。
    心跳(BEAT) 心跳消息。
    心跳确认(Beat-Ack) 确认心跳消息。
    通知(NTFY) 为M3UA对等体提供事件的自主指示。

    M3UA错误消息处理

    错误代码 响应 原因 操作
    版本无效 ASP UP 用于通知ASP SG不支持指定版本。仅当向SG发送ASP Up请求时，才应收到此错误。 目前，只有一个M3UA版本。
    不支持的消息类 全部 向SG或ASP表示收到消息时消息类无效。 当ASP收到消息类不受支持时，它会忽略该消息，将报头置于错误消息的诊断参数中，并发送包含此错误代码的错误消息。收到此错误消息后，将记录该消息。
    不支持的消息类型 全部 向SG或ASP表示收到的消息类型无效。 与上述不支持的消息类相同。
    不支持的流量处理模式 ASPAC 通知收到消息的ASP其包含无效的流量处理类型。 收到此错误消息后，ASP应生成日志条目并通过层管理回调提供配置不匹配通知。
    意外消息     当意外收到消息时发送（即，ASP不处于活动状态或ASP处于关闭状态，并且收到ASP活动）。
    协议错误     已记录（如果收到）。因一般协议错误而发送。
    流标识符无效   当收到具有无效流标识符的消息时，对等体发送。当管理消息在流0之外的流上发送时，就会发生这种情况。无效流上消息的接收方应丢弃该消息。 收到此消息时，很可能出现编码错误。收到此消息后，应在有效流中再次发送该消息，并记录错误。
    拒绝 — 管理阻止 ASP Up ASP Act SG在收到ASP UP或ASP Act时发送，并出现某种形式的管理阻塞。 已记录（如果收到）。如果首选状态为UP，ASP会继续定期发送ASP UP或ASP ACT消息。
    需要ASP标识符 ASP UP 由信令网关进程(SGP)发送，以响应没有ASP标识符的ASP UP。 已记录（如果收到）。但是，由于已发送ASP ID，因此不应收到此消息。
    ASP标识符无效 ASP UP 为响应ASP UP消息而发送，ASP标识符重复。 已记录（如果收到）。
    无效的路由上下文 ASPAC ASPAA NTFY 当邮件包含无效的路由上下文时发送。 已记录（如果收到）。此外，会发送层管理通知，以警告PGW 2200和SG之间的配置不匹配。
    参数值无效 all 收到消息时，对等设备发送的消息的参数值无效。 已记录（如果已接收）
    参数字段错误 all   已记录（如果收到）。
    意外参数 all 在消息中收到意外参数时发送。 已记录（如果收到）。
    目标状态未知 DAUD 发送以响应DAUD到ASP，指示SG不想提供状态。 已记录（如果收到）。此外，还会发送层管理通知以生成错误配置警报。
    网络外观无效 数据DUNA DAVA DAUD SCON DUPU DRST 接收实体（SG或ASP）无法识别网络外观参数。  

    在以下示例中，关联变为Out-of-Service(OOS)，并遵循信令流。(请参阅粗体信息。)
