簡介

本文檔提供了基本網守呼叫准入控制的示例配置。

必要條件

需求

在網關能夠從網守獲得正確的地址解析之前，需要滿足幾個條件。當涉及低速鏈路時，每個VoIP解決方案都有幾個重要點需要驗證。

嘗試此設定之前，請確保符合以下要求：

  • 所有網關都應註冊到相應的網守

  • 所有網守都應具有正確的撥號計畫，以便他們能夠決定呼叫的路由。

  • 准入控制可以配置為限制某些區域之間的呼叫號碼。

由於配置部分考慮了前兩點，因此我們將重點介紹「背景資訊」部分中的准入控制。

採用元件

本文中的資訊係根據以下軟體和硬體版本：

  • 三台Cisco 2600路由器。

  • Cisco IOS®軟體版本12.2.8.5 ENTERPRISE PLUS/H323 MCM。

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您在即時網路中工作，請確保在使用任何命令之前瞭解其潛在影響。

慣例

如需文件慣例的詳細資訊，請參閱思科技術提示慣例。

背景資訊

此示例配置研究具有雙區域拓撲的VoIP網路，該網路由在兩個區域中均具有三個網關的一個網守管理。本文檔的目的是提供一個准入控制配置的簡單示例，該配置將策略應用於區域之間及其內部的呼叫數。本文包含有關已設定功能、設計准則、基本驗證和疑難排解策略的技術背景資訊。

注意：在此配置中，四台路由器位於同一個LAN中。但是，在實際拓撲中，所有裝置都可能位於網路的不同部分。

在實際網路中，高優先順序流量的來源通常有多種。區分這些條件是一項複雜的工作，因為它們數量眾多，而且容易被忽視。然而，在現實生活中經常發生的幾種常見情況值得考慮。當提供流量優先順序的路由器本身不是此類流量的來源時，准入控制就成為一個問題。典型的拓撲涉及兩個站點上的多個語音網關，這些語音網關通過一對路由器提供的鏈路連線。另一種拓撲涉及兩個站點上具有IP電話的Cisco CallManager，以及PSTN或PBX的網關。在這兩種情況下，我們都有多個來自鏈路兩端的語音流量來源。

add_control1.gif

有時，如果語音流量超過了優先順序隊列配置的頻寬，則語音品質可能會出現問題。這是因為產生流量的路由器和Cisco CallManager/IP電話在上面給出的設計中沒有對呼叫准入的集中管理。在這種情況下，超出頻寬的封包將被捨棄。

有幾種方法可避免這種情況。最簡單的解決方案是在低延遲隊列(LLQ)中配置語音頻寬，以接受來自所有源的最大呼叫數。如果沒有語音流量，則未使用的頻寬將被授予資料流。當鏈路的總頻寬大於最大呼叫數所需的頻寬時，可以完成此操作。

更明智的方法是對來自鏈路兩端的每個語音流量源應用限制。執行此操作時，來自所有站點的總頻寬將不會超過建議站點間鏈路實際頻寬的75%。要應用這些限制，請使用VoIP撥號對等體配置下的max-conn命令。如果我們假設僅在一個中心站點存在Cisco CallManager，我們可以使用其功能限制到沒有CallManager的分支站點的呼叫數。此方法允許我們管理語音流量來源可能超額訂閱連結的情況。這種方法的缺點是不能靈活使用授予源的頻寬。此方法不允許某些網關發出額外呼叫，即使此時有可用頻寬。

最靈活的方法是使用單獨的實體進行集中呼叫准入控制：守門員。網守幫助將兩個站點與兩個Cisco CallManager（或CallManager集群）繫結。

附註：  使用網守並不一定意味著購買新的獨立路由器。根據呼叫數量和路由器的負載，您可以使用適當的Cisco IOS功能集為Enterprise/PLUS/H323，在現有路由器之一上配置網守。這有助於管理小型分支機構，並僅允許在中心站點配置專用網守。

應謹慎考慮網守方法，以免路由器承受額外的負載。此外，您應檢查拓撲是否允許以這種方式設定網守以避免關鍵鏈路上的額外流量。

一般建議使用單獨的思科路由器作為網路中的專用網守，其數量適合您的拓撲。

請考慮以上拓撲。在這裡，您可以將所有裝置放入由單個網守管理的兩個本地區域中。這允許您在每個區域中有大量呼叫，但會限制它們之間的呼叫數。在我們的測試示例中，我們將兩個區域之間的頻寬限製為一個呼叫，並允許其中一個區域最多兩個（較多數）呼叫。

有關此問題的詳細資訊，請參閱VoIP呼叫准入控制。

要完成任務，請使用思科高效能閘道管理員中介紹的bandwidth(gatekeeper)命令

bandwidth(gatekeeper)指令

要指定H.323流量的最大聚合頻寬，請使用bandwidth gatekeeper配置命令。要禁用該功能，請使用此命令的no形式。

注意：此命令允許您限制通過來自區域的單個鏈路的頻寬。如果拓撲允許您通過多條路徑從一個區域到另一個區域發出呼叫，則鏈路很容易會超額使用。請考慮使用此拓樸：兩個區域通過兩條路徑連線，每個路徑只允許一個呼叫。如果頻寬受一次呼叫的限制，則不會使用第二條路徑。但如果頻寬受兩個呼叫的限制，則其中一條鏈路可能會超額使用。因此，此命令可以應用於只有一個路徑到達所有其他區域的區域。「集中星型」拓撲是一個例外。雖然集線器有多個路徑，但它不會超額訂閱鏈路，因為每個鏈路的分支上的呼叫數量會受到限制。

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

無頻寬{interzone |總計 | session} {default | zone zone-name} bandwidth-size

語法說明

下表介紹了語法：

語法 說明
interzone 指定從區域到任何其他區域的H.323流量的總頻寬量。
總計 指定區域中允許的H.323流量的總頻寬量。
會話 指定區域中會話允許的最大頻寬。
預設 指定所有區域的預設值。
區域 zone-name 指定特定區域。為特定區域命名。
頻寬大小 最大頻寬。對於interzone和total，範圍是從1到10,000,000 kbps。session的範圍是從1到5,000 kbps。

命令模式

網守配置

命令歷史記錄

下表描述了命令歷史記錄：

版本 修改
12.1(3)XI 引入了此命令。
12.1(5)XM 未使用zone gatekeeper命令即可識別bandwidth命令。
12.2(2)噸 此命令已整合到Cisco IOS軟體版本12.2(2)T中。
12.2(2)XB1 此命令在Cisco AS5850通用網關上實施。

使用指南

在先前的Cisco IOS軟體版本中，bandwidth指令的功能是使用zone gatekeeper指令取得的。

範例

以下示例將區域的最大頻寬配置為5,000 kbps:

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

相關命令

bandwidth remote — 指定此網守與任何其他網守之間的H.323流量的總頻寬。

設定

網路圖表

本檔案會使用以下網路設定：

add_control2.gif

組態

目標是將zone1和zone3之間的可用頻寬限製為一個呼叫，並允許zone1中有更多呼叫（在本示例中最多兩個呼叫）。因此，我們將滿足典型呼叫准入任務的常規要求。註冊、准入和狀態協定(RAS)消息先於H225呼叫建立消息。接著H4245協商，它實際上定義了雙方的能力。因此在呼叫准入階段和RAS消息交換之後定義呼叫的實際頻寬。因此，網守將每個呼叫視為64kb呼叫。因此，應該以64kb的增量增加語音呼叫區域之間的頻寬限制。

注意：GW_3與網守配置在同一路由器上，以說明低端分支機構的這種可能性。

註：驗證網守和網關配置是排除GK-GW問題的重要部分。因此，為了簡化對配置的理解，已刪除了所有不相關的配置命令。
