簡介

本文檔中介紹的示例配置顯示了使用非同步傳輸模式(PPPoA)上的點對點協定訪問Internet服務提供商(ISP)網路的遠端客戶端。

遠端使用者端想要使用第3層服務選取閘道/服務選取儀表板(SSG/SSD)存取第2層通道通訊協定(L2TP)服務。L2TP服務在配置中以主機IP地址15.15.15.5表示。使用動態主機配置協定(DHCP)，Cisco 677為PC提供從10.0.0.2到10.0.0.254的IP地址池的IP地址，掩碼為255.255.255.0。此外，在Cisco 677上啟用了埠地址轉換(PAT)。

此配置示例有三項測試：

遠端客戶端登入服務的不同步驟期間與SSG相關的調試。
單一登入SSD 2.5.1功能。
啟用SSD調試。

在實施新配置之前，您必須將Cisco 677重置為其預設配置。要恢復預設配置，請使用set nvram erase命令；例如：

cbos#set nvram erase
Erasing running configuration.
You must use "write" for changes to be permanent.

cbos#write
NVRAM written.

cbos#reboot

在思科677思科寬頻作業系統(CBOS)上啟用DHCP伺服器功能會自動建立名為「pool0」的池，並分配子網為10.0.0.0，子網掩碼為255.255.255.0。預設情況下，Cisco 677乙太網介面的IP地址分配為10.0.0.1，然後「pool0」可以為本地LAN客戶端/PC租用10.0.0.2到10.0.0.254之間的IP地址。

疑難排解

單一登入SSD 2.5.1功能是什麼？

此功能適用於SSD伺服器。當SSD伺服器在其快取資料庫中找不到傳送HTTP流量的遠端客戶端的主機對象時，它會向SSG傳送訪問請求。如果SSG具有主機對象，則會向SSD傳送訪問接受消息。然後，使用者可以授予對服務的訪問許可權。

如果SSD或SSG上沒有主機物件，則使用者應該使用一般的SSD登入驗證程式在SSD上進行驗證。

配置SSG和SSD之前需要瞭解什麼？

在配置SSD或SSG之前，您必須驗證以下內容：

SSD、SSG以及身份驗證、授權和記帳(AAA)均在運行，並且所有網路實體可以彼此ping通。
遠端使用者可以在登入到SSG伺服器之前，對預設網路(SSG、SSD、AAA)中的任何主機執行ping操作。
網路訪問提供程式(NAP)（在本例中為Cisco 6400 NRP1）可以ping服務目標網路。
遠端客戶端無法ping遠端服務目標網路。

啟動PPPoA會話之後，但在設定SSD登入之前，該怎麼做？

配置完所有SSG命令後，您必須驗證是否已成功下載使用者服務的下一跳表。發出show ssg binding命令。

arielle_nrp3# show ssg binding
cairo.com_key        -> 14.14.14.5 (NHT)

arielle_nrp3# show ssg next-hop
Next hop table loaded from profile nxthoptbl:
cairo.com_key        -> 14.14.14.5
End of next hop table.

檢查所有方向繫結在SSG上是否都處於活動狀態。

arielle_nrp3# show ssg direction
Virtual-Template66: Downlink

當客戶端向SSD伺服器啟動HTTP會話時，使用者將看到SSD伺服器登入首頁。

注意：請記住發出UNIX shell命令root@crazyball[/export/home/ssd251/ssd]startSSD.sh啟動SSD伺服器操作。

如何測試SSD單一登入功能？

配置dashboard.conf檔案中的引數(REAUTHENTICATE=off)。預設值為REAUTHENTICATE=on。
登入SSD上的任何網頁。例如，當您登入cairo.com服務首頁時，請關閉瀏覽器，然後使用http://10.200.56.40:8080再次開啟瀏覽器。

SSD上的主機物件仍在快取記憶體中，因此您應該能夠再次登入先前登入的SSD服務頁面。預設行為是在SSD上重新進行身份驗證；也就是說，您必須轉到SSD登入首頁。

如何執行SSD偵錯？

在瀏覽器的位址列中鍵入https://10.200.56.40:8443/log。
按一下Set Option。您選取的所有偵錯都會執行，而輸出會記錄在記錄檔中。日誌檔名的格式為yy_mm_dd.request.log。
導航到SSD伺服器上日誌檔案所在的目錄。
使用UNIX編輯器打開檔案/export/home/ssd251/ssd/logs]vi yy_mm_dd.request.log以檢視調試輸出。
