لغة خالية من التحيز

تسعى مجموعة الوثائق لهذا المنتج جاهدة لاستخدام لغة خالية من التحيز. لأغراض مجموعة الوثائق هذه، يتم تعريف "خالية من التحيز" على أنها لغة لا تعني التمييز على أساس العمر، والإعاقة، والجنس، والهوية العرقية، والهوية الإثنية، والتوجه الجنسي، والحالة الاجتماعية والاقتصادية، والتمييز متعدد الجوانب. قد تكون الاستثناءات موجودة في الوثائق بسبب اللغة التي يتم تشفيرها بشكل ثابت في واجهات المستخدم الخاصة ببرنامج المنتج، أو اللغة المستخدمة بناءً على وثائق RFP، أو اللغة التي يستخدمها منتج الجهة الخارجية المُشار إليه. تعرّف على المزيد حول كيفية استخدام Cisco للغة الشاملة.

حول هذه الترجمة

ترجمت Cisco هذا المستند باستخدام مجموعة من التقنيات الآلية والبشرية لتقديم محتوى دعم للمستخدمين في جميع أنحاء العالم بلغتهم الخاصة. يُرجى ملاحظة أن أفضل ترجمة آلية لن تكون دقيقة كما هو الحال مع الترجمة الاحترافية التي يقدمها مترجم محترف. تخلي Cisco Systems مسئوليتها عن دقة هذه الترجمات وتُوصي بالرجوع دائمًا إلى المستند الإنجليزي الأصلي (الرابط متوفر).

المقدمة

في العديد من البيئات، يلزمك تكوين خادم وصول يمكنه قبول المكالمات الواردة من مستخدمي Async و ISDN على حد سواء. ويمكن لهؤلاء المستخدمين بعد ذلك الاتصال بالشبكة بسلاسة كما لو كانوا حاضرين ماديا. يستخدم هذا الإعداد بشكل شائع لتوفير إمكانية الاتصال بالشبكة للمستخدمين الذين يسافرون ويعملون من بعد، وكذلك لمواقع المكاتب المنزلية الصغيرة (SOHO).

يوضح هذا المستند كيفية تكوين خادم Access لقبول مكالمات Async و ISDN الواردة على دارات ISDN T1 PRI. يوفر التكوين الحد الأدنى للإعداد المطلوب لخادم الوصول إلى الشبكة (NAS) لقبول المكالمة. يمكنك إضافة ميزات إضافية إلى هذا التكوين استنادا إلى إحتياجاتك.

المتطلبات الأساسية

المتطلبات

لا توجد متطلبات خاصة لهذا المستند.

المكونات المستخدمة

تستند المعلومات الواردة في هذا المستند إلى إصدارات البرامج والمكونات المادية التالية:

  • Cisco AS5300 مع 192 أجهزة مودم MICA وثمانية منافذ T1 التي تعمل ببرنامج Cisco IOS® الإصدار 12.2(5).

  • إثنان من PRI T1.

  • كمبيوتر يعمل بنظام التشغيل Microsoft Windows. يحتوي هذا الكمبيوتر على مودم تناظري واتصال هاتف بشبكة هاتف المحول العام. يقوم الكمبيوتر بحفظ T1 PRI المتصل ب AS5300.

  • موجهات السلسلتان 800 و 1600 من Cisco مع دوائر ISDN BRI. هذه الموجهات هي عملاء اتصال ISDN. يتم توفير التكوين ل Cisco 1600. يمكنك تطبيق تكوين العميل هذا على أي موجه باستخدام واجهة BRI.

  • المصادقة والتفويض والمحاسبة المحلية (AAA). إذا كان لديك خادم AAA RADIUS أو TACACS+، فيمكنك إستخدام أي منهما لتوفير AAA للمكالمات الواردة.

ملاحظة: تكوين الموجه Cisco 800 مماثل لتكوين الموجه Cisco 1600، ولا يتم تضمينه في هذا المستند.

تم إنشاء المعلومات الواردة في هذا المستند من الأجهزة الموجودة في بيئة معملية خاصة. بدأت جميع الأجهزة المُستخدمة في هذا المستند بتكوين ممسوح (افتراضي). إذا كانت شبكتك مباشرة، فتأكد من فهمك للتأثير المحتمل لأي أمر.

المنتجات ذات الصلة

يمكنك إستخدام هذا التكوين مع أي موجه يحتوي على بطاقات T1 أو PRI ومودم رقمي داخلي (على سبيل المثال، MICA أو NextPort أو Microcom). ويمكن لأي موجه من سلسلة AS5xxx مزود ببطاقة T1 أو PRI ومودم رقمية إستخدام المفاهيم في هذا التكوين.

لا تدعم الموجهات من السلسلة Cisco 2600 أجهزة المودم الرقمية الداخلية. يمكنك تكوين موجهات سلسلة Cisco 2600 لقبول مكالمات ISDN فقط، شريطة أن يحتوي الموجه على T1 أو PRI WIC أو وحدة الشبكة النمطية.

يمكن لموجهات سلسلة 3600 من Cisco دعم كل من مكالمات ISDN والمودم. ومع ذلك، تتطلب الموجهات من السلسلة Cisco 3600 وجود بطاقة واجهة شبكة (WIC) أو PRI T1 أو وحدة شبكة، الوحدة النمطية لشبكة المودم الرقمي NM-xDM.

أنت يستطيع أيضا جعلت تعديل أن يستعمل هذا تشكيل مع E1 أو PRI ميناء. قم بتكوين وحدة التحكم في الفئة E1 باستخدام إنشاء الخط والإطار والخصائص المادية الأخرى التي يوفرها Telco لديك. تكوين قناة D (الواجهة serial x:15 ل E1s) مماثل للتكوين المبين في هذا المستند.

التحقق من الصحة

يوفر هذا القسم معلومات يمكنك إستخدامها للتأكد من أن التكوين يعمل بشكل صحيح.

يتم دعم بعض أوامر العرض بواسطة أداة مترجم الإخراج (العملاء المسجلون فقط)، والتي تتيح لك عرض تحليل إخراج أمر العرض.

  • show isdn status— يضمن أن الموجه يتصل بشكل صحيح مع محول ISDN. في المخرجات، تأكد من أن حالة الطبقة 1 هي نشطة، وأن حالة الطبقة 2 = MULTI_FRAME_ESTABLISHED تظهر. يعرض هذا الأمر أيضا عدد المكالمات النشطة. راجع إستخدام الأمر show isdn status لاستكشاف أخطاء BRI وإصلاحها للحصول على مزيد من المعلومات.

  • show ppp multilink— يعرض معلومات عن الحزم متعددة الارتباطات النشطة. أستخدم هذا الأمر للتحقق من الاتصال متعدد الارتباطات.

  • show dialer [نوع الواجهة number]—يعرض معلومات التشخيص العامة للواجهات التي تم تكوينها ل DDR. في حالة ظهور المتصل بشكل صحيح، يجب أن تظهر حالة المتصل وهي عبارة عن رسالة طبقة إرتباط بيانات. إذا ظهرت الطبقة المادية لأعلى، فإن التلميح هو أن بروتوكول الخط ظهر، لكن بروتوكول التحكم في الشبكة (NCP) لم يظهر. يتم عرض عناوين المصدر والوجهة للحزمة التي بدأت الطلب في سطر سبب الطلب. يعرض هذا الأمر show أيضا تكوين المؤقت، والوقت قبل انتهاء مهلة الاتصال.

  • إظهار تفاصيل اسم مستخدم المتصل—يعرض معلمات للمستخدم المعين، على سبيل المثال، معلمات عنوان IP المعين و PPP وحزمت PPP. إذا لم يدعم إصدار برنامج Cisco IOS هذا الأمر، فاستخدم الأمر show user.

  • إظهار خريطة المتصل—يعرض خرائط المتصل الديناميكية والثابتة التي تم تكوينها. يمكنك إستخدام هذا الأمر للتحقق مما إذا تم إنشاء خريطة متصل ديناميكي. لا يمكنك توجيه الحزم بدون خريطة المتصل.

أوامر استكشاف الأخطاء وإصلاحها

يتم دعم بعض أوامر العرض بواسطة أداة مترجم الإخراج (العملاء المسجلون فقط)، والتي تتيح لك عرض تحليل إخراج أمر العرض.

ملاحظة: قبل إصدار أوامر تصحيح الأخطاء، يرجى الاطلاع على المعلومات المهمة في أوامر تصحيح الأخطاء.

  • debug dialer—يعرض معلومات تصحيح أخطاء DDR حول الحزم المستلمة على واجهة المتصل. يمكن أن تساعد هذه المعلومات في ضمان وجود حركة مرور مثيرة للاهتمام تستخدم واجهة المتصل.

  • debug isdn q931—يعرض إعداد الاستدعاءات وتخريب اتصال شبكة ISDN (الطبقة 3).

  • debug modem—يعرض نشاط خط المودم على خادم الوصول. يعرض الإخراج عند تغيير حالة خط المودم.

  • debug modem csm— يمكنك من أستكشاف أخطاء وحدة تحويل المكالمات النمطية (CSM) وإصلاحها على الموجهات التي تحتوي على أجهزة مودم رقمية داخلية. باستخدام هذا الأمر، يمكنك تتبع التسلسل الكامل لتحويل المكالمات الواردة والصادرة.

  • debug ppp negotiation—يعرض معلومات حول حركة مرور بيانات PPP وعمليات تبادلها، ويتفاوض على بروتوكول التحكم في الارتباط (LCP) والمصادقة وبروتوكول التحكم في الشبكة (NCP). يقوم تفاوض PPP الناجح أولا بفتح حالة LCP، ثم يقوم بالمصادقة، وأخيرا بالتفاوض على NCP. يتم إنشاء معلمات الارتباط المتعدد مثل وحدة الاستقبال المعاد إنشاؤها القصوى (MRRU) أثناء تفاوض LCP.

  • debug ppp authentication—يعرض رسائل بروتوكول مصادقة PPP، بما في ذلك عمليات تبادل حزم CHAP ومصادقة كلمة المرور (PAP).

  • تصحيح أخطاء PPP—يعرض أخطاء البروتوكول وإحصائيات الخطأ المرتبطة بالتفاوض حول اتصال PPP وتشغيله.

إخراج تصحيح الأخطاء للعينة
