简介

本文档提供基本网守呼叫准入控制的示例配置。

先决条件

要求

在网关能够从网守获取正确的地址解析之前，需要满足几个条件。当涉及低速链路时，每个VoIP解决方案都需要验证几个重要点。

在尝试此配置前，请保证您符合这些要求：

  • 所有网关都应注册到相应的网守

  • 所有网守都应具有正确的拨号方案，以便他们可以决定呼叫的路由。

  • 准入控制可配置为限制某些区域之间的呼叫号码。

由于前两点在“配置”部分中考虑，因此我们将重点介绍“背景信息”部分的准入控制。

使用的组件

本文档中的信息基于以下软件和硬件版本：

  • 三台Cisco 2600路由器。

  • Cisco IOS®软件版本12.2.8.5 ENTERPRISE PLUS/H323 MCM。

本文档中的信息都是基于特定实验室环境中的设备创建的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您是在真实网络上操作，请确保您在使用任何命令前已经了解其潜在影响。

规则

有关文档规则的详细信息，请参阅 Cisco 技术提示规则。

背景信息

此配置示例研究具有两区域拓扑的VoIP网络，该拓扑由一个网守管理，两个区域中有三个网关。本文档旨在提供一个简单的准入控制配置示例，该配置将策略应用于区域之间和区域内的呼叫数。本文档包括有关已配置功能、设计指南以及基本验证和故障排除策略的技术背景信息。

注意：在此配置中，四台路由器位于同一LAN中。然而，在您的实际结构中，所有设备可以在您网络的不同部分中使用。

通常，实际网络中存在多个高优先级流量源。区分所有这些条件是一项复杂的任务，因为这些条件数量众多且易于忽略。然而，在现实生活中经常发生的几种常见情况值得考虑。当提供流量优先级的路由器本身不是此类流量的源时，准入控制就成为问题。典型的拓扑包括通过一对路由器提供的链路连接的两个站点的多个语音网关。另一种拓扑涉及两个站点的Cisco CallManager和IP电话，以及PSTN或PBX网关。在这两种情况下，我们都有来自链路两端的多个语音流量源。

add_control1.gif

有时，如果语音流量超出优先级队列的已配置带宽，则语音质量可能会出现问题。这是因为在上述设计中，发起流量的路由器和Cisco CallManager/ IP电话没有集中管理呼叫准入。在这种情况下，超过带宽的数据包将被丢弃。

有多种方法可避免此场景。最简单的解决方案是配置低延迟队列(LLQ)中的语音带宽，以接受来自所有来源的最大呼叫数。如果没有语音流量，则会向数据流授予未使用的带宽。当链路的总带宽高于最大呼叫数所需的带宽时，可以执行此操作。

更明智的方法是对来自链路两端的语音流量的每个源应用限制。执行此操作时，来自所有站点的汇总带宽不会超过站点间链路实际带宽的75%。要应用这些限制，请在VoIP拨号对等体配置下使用max-conn命令。如果我们假设只有一个中心站点有Cisco CallManager，我们可以使用其功能来限制到分支站点的呼叫数，而无需CallManager。通过此方法，我们可以管理语音流量源能够超订用链路的情况。此方法的缺点是对授予源的带宽使用不灵活。此方法不允许某些网关发出额外呼叫，即使此时有可用的空闲带宽。

最灵活的方法是使用单独的实体进行集中呼叫准入控制：网守。网守帮助将两个站点与两个Cisco CallManager（或CallManager集群）绑定。

注意：  使用网守并不总是意味着购买新的独立路由器。根据呼叫数和路由器负载，您可以在现有路由器中的一台路由器上配置网守，并将相应的Cisco IOS功能设置为Enterprise/PLUS/H323。这有助于管理小型分支机构，并仅允许中心站点中的专用网守。

网守方法应谨慎考虑，以免给路由器增加负载。此外，您应检查拓扑是否允许将网守置于这样的位置，以避免关键链路上的额外流量。

一般建议使用单独的思科路由器作为您网络中的专用网守，编号与您的拓扑相符。

请考虑上述拓扑。在这里，您可以将所有设备放入由单个网守管理的两个本地区域。这样，您可以在每个区域拥有大量呼叫，但会限制它们之间的呼叫数。在我们的测试示例中，我们将两个区域之间的带宽限制为一个呼叫，并允许其中一个呼叫中最多两个（数量较大）呼叫。

有关此的更多详细信息，请参阅VoIP呼叫准入控制。

要完成任务，请使用Cisco高性能网守中描述的bandwidth（网守）命令

bandwidth (gatekeeper) 命令

要指定H.323流量的最大聚合带宽，请使用bandwidth 网守配置命令。要禁用该功能，请使用此命令的no形式。

注意：此命令允许您通过来自区域的单个链路限制带宽。如果拓扑允许您通过多条路径从一个区域到另一个区域进行呼叫，则链路很容易超订用。请考虑以下拓扑：两个区域通过两条路径连接，每条路径仅允许一个呼叫。如果带宽受到一个呼叫的限制，则不会使用第二条路径。但是，如果带宽受两个呼叫的限制，其中一个链路可能超订用。因此，此命令可应用于只有一条路径通往所有其他区域的区域。“中心辐射型”拓扑是个例外。虽然集线器有多条路径，但它不会超订用链路，因为每条链路的分支处的呼叫数将受到限制。

bandwidth {interzone |总计 | session} {default | zone zone-name} bandwidth-size

no bandwidth {interzone |总计 | session} {default | zone zone-name} bandwidth-size

语法说明

下表对语法进行了说明：

语法 描述
interzone 指定从区域到任何其他区域的H.323流量的总带宽量。
总数 指定区域中允许的H.323流量的总带宽量。
会话 指定区域中会话允许的最大带宽。
默认 指定所有区域的默认值。
区域 zone-name 指定特定区域。命名特定区域。
带宽大小 最大带宽.对于区间和总数，范围为1到10,000,000 kbps。对于session，范围为1到5,000 kbps。

默认设置

无

命令模式

网守配置

命令历史记录

下表对命令历史记录进行了说明：

版本 修改
12.1(3)XI 引入此指令。
12.1(5)XM 不使用zone gatekeeper命令，bandwidth命令就可以识别。
12.2(2)T 此命令已集成到Cisco IOS软件版本12.2(2)T。
12.2(2)XB1 此命令在Cisco AS5850通用网关上实施。

使用指南

在以前的Cisco IOS软件版本中，bandwidth命令的功能是通过使用zone gatekeeper命令获得的。

Examples

以下示例将区域的最大带宽配置为5,000 kbps:

Router(config)# gatekeeper
Router(config-gk)# bandwidth total default 5000

相关命令

bandwidth remote — 指定此网守和任何其他网守之间H.323流量的总带宽。

配置

网络图

本文档使用以下网络设置：

配置

目标是将区域1和区域3之间的可用带宽限制为一个呼叫，并允许区域1中更多的呼叫（本例中最多两个）。因此，我们将满足典型呼叫准入任务的一般要求。注册、准入和状态协议(RAS)消息在H225呼叫建立消息之前。然后H4245协商，它实际上定义了双方的能力。因此，呼叫的实际带宽是在呼叫准入阶段和RAS消息交换之后定义的。因此，网守将每个呼叫视为64kb的呼叫。因此，语音呼叫区域之间带宽限制的增加应以64kb的增量完成。

注意：GW_3配置在与网守相同的路由器上，以说明低端分支机构的这种可能性。

注意：验证网守和网关配置是排除GK-GW故障的重要部分。因此，为简化对配置的了解，删除了所有不相关的配置命令。
