簡介

此組態說明遠端思科3640具有內部8埠類比資料機卡(NM-8AM)，撥入具有主要速率介面(PRI)的思科AS5300。 此配置描述了由遠端站點上的兩條模擬電話線組成的多鏈路連線。如果電話線路可用，則可以為MP配置更多電話線路。

慣例

背景理論

多鏈路PPP(MP)允許裝置通過多個點對點資料鏈路通過實施虛擬鏈路將資料傳送到同一目標。MP連線的最大頻寬等於分量鏈路頻寬的總和。MP可以配置為多路複用鏈路（如ISDN和幀中繼），也可以配置為多個非同步線路。如需MP的詳細資訊，請參閱RFC 1990 leavingcisco.com 。

注意：RFC 1990將多鏈路PPP稱為MP。已知MP的其他名稱包括MPPP、MLP和多鏈路。

非同步MP可用於以比單個模擬連線更高的速度連線遠端客戶端。在Async MP中，遠端客戶端使用多個數據機（因此使用多條電話線路）撥入中心路由器並訪問網路。由於多條電話線路通常比ISDN基本速率介面(BRI)服務更便宜，因此Async MP提供了一種有效的方法，可在控制成本的同時提高遠端使用者的連線速度。非同步MP也是為無法由ISDN服務的遠端區域獲取更高訪問速度的有效方式。

非同步MP將單獨的數據機連線捆綁到訪問伺服器。每個對等體上的PPP軟體將資料包分段，然後通過多個模擬連線將片段傳輸到另一端。接收端從獨立的連線中收集這些片段，並根據其中嵌入的MP資訊將這些片段重組為有效的資料包，從而提供具有更高頻寬的端到端虛擬鏈路。非同步MP可以在兩台路由器之間或路由器和客戶端PC之間配置。

調整和可選命令

以下命令可用於調整MP連線的行為。仔細調整此類引數可以避免浪費和不必要的資料鏈路使用，從而有助於控制成本。

  • dialer load-threshold load [outbound |入站 |任一]

    可以配置MP，以便在主通道建立後立即啟動其它通道。要設定此場景，請在dialer load-thershold load命令中將負載閾值設定為1。在這種情況下，會調出其他通道並繼續保持活動狀態（即，它們不會翻動）。 如果負載閾值設定為任何其他值，則多個通道可能會隨著鏈路上的負載而擺動。如果希望根據需要新增其他通道，請根據流量將負載閾值設定為介於1和255之間的適當值。例如，如果附加通道達到50%，則閾值應設定為128(0.50*255)。 在確定閾值時，必須考慮非同步呼叫的設定時間，因為設定時間較長可能會使閾值較低。

    您可以根據傳出、傳入或傳入介面上的傳入或傳出流量中的較高者來計算負載。如果將負載基於入站或兩者之一，請確保中心站點配置了passive-interface Group-Async1，以便不會通過非同步線路傳送來自核心的路由更新。阻止路由流量通過鏈路可為線路上的其他資料提供更多頻寬。

  • ppp timeout multilink link remove seconds

    此命令可用於防止在負載變化時多鏈路連線抖動。例如，當負載閾值設定為15（即15/255=6%）且流量超過閾值時，會啟動額外的線路。當流量低於閾值時，會丟棄額外的線路。在資料速率具有高度可變性的情況下，有利的是多通道保持運行指定時間段，即使負載閾值低於指定值。將此多鏈路超時分配給小於dialer idle-timeout指定的時間，該時間控制所有鏈路的超時。

  • ppp timeout multilink link add seconds

    此命令可用於防止將多個鏈路新增到MP捆綁包，直到在指定間隔內收到高流量。這可防止突發流量不必要地增加線路。

驗證

本節提供的資訊可用於確認您的組態是否正常運作。

輸出直譯器工具支援某些show命令，該工具允許您檢視show命令輸出的分析。

  • show ppp multilink — 顯示處於活動狀態的多鏈路捆綁包的資訊。應使用此命令驗證多鏈路連線。

  • show caller — 顯示NAS上各個使用者和消耗資源的資訊。此命令顯示大型連線池的活動呼叫統計資訊，並顯示每個使用者的絕對和空閒時間。如果您的Cisco IOS軟體版本不支援此命令，請使用show user命令。

  • show caller user — 顯示特定使用者的引數，如使用的TTY線路、非同步介面（機架/插槽/埠）、DS0通道號、數據機號、分配的IP地址、PPP和PPP捆綁引數等。如果您的Cisco IOS軟體版本不支援此命令，請使用show user命令。

疑難排解

本節提供的資訊可用於對組態進行疑難排解。

疑難排解程序

對MP連線進行故障排除時，請按照呼叫進行時的方式繼續操作：

以下提供debug輸出範例，並標有關於尋找什麼的解釋。

測試MP配置時，請確保通過鏈路生成足夠的流量以觸發負載閾值。您可以在測試過程中根據需要調整負載閾值。

  1. 使用debug dialer和debug chat命令驗證撥號器是否正確撥號。

  2. 確認PPP協商和身份驗證成功。請注意LCP協商，其中協商MP引數行Maximum Receive Reconstructed Unit(MRRU)和端點鑑別器(EndpointDisc)。

  3. 驗證鏈路是否已正確虛擬化。Cisco IOS軟體將建立一個虛擬訪問介面來表示MP捆綁包。

  4. 驗證網際網路通訊協定控制通訊協定(IPCP)交涉是否成功。注意是否分配了正確的IP地址以及是否安裝了正確的路由。

疑難排解指令

輸出直譯器工具支援某些show命令，該工具允許您檢視show命令輸出的分析。

注意：發出debug指令之前，請先參閱有關Debug指令的重要資訊。

  • debug vtemplate — 顯示虛擬訪問介面的克隆資訊，從從虛擬模板克隆到斷開時為止。

  • debug ppp multilink events — 顯示影響多鏈路捆綁的事件資訊。

  • debug ppp negotiation — 在協商鏈路控制協定(LCP)、身份驗證和網路控制協定(NCP)時顯示有關PPP流量和交換的資訊。成功的PPP協商將首先開啟LCP狀態，然後進行身份驗證，最後協商NCP。在LCP協商期間建立諸如最大接收重建單元(MRRU)的多鏈路引數。

  • debug ppp authentication — 顯示PPP身份驗證協定消息，包括質詢握手身份驗證協定(CHAP)資料包交換和口令身份驗證協定(PAP)交換。

  • debug ppp error — 顯示與PPP連線協商和操作相關的協定錯誤和錯誤統計資訊。
