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 ip route - يعرض إدخالات جدول توجيه IP.
show interfaces - يعرض إحصائيات لجميع الواجهات التي تم تكوينها على الموجه أو خادم الوصول.
يوفر هذا القسم معلومات يمكنك استخدامها لاستكشاف أخطاء التكوين 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 isdn q931 - يعرض معلومات حول إعداد المكالمات وإنزال إتصالات شبكة ISDN (الطبقة 3) بين الموجه المحلي (جانب المستخدم) والشبكة.
debug isdn events - يعرض أحداث ISDN التي تحدث على جانب المستخدم (على الموجه) لواجهة ISDN. أحداث ISDN التي يمكن عرضها هي أحداث Q.931 (إعداد الاستدعاء وخفض إتصالات شبكة ISDN).
debug dialer - يعرض معلومات تصحيح الأخطاء حول الحزم أو الأحداث على واجهة المتصل.
debug ppp negotiation - يسبب الأمر debug ppp لعرض حزم PPP التي يتم إرسالها أثناء بدء تشغيل PPP، حيث يتم التفاوض مع خيارات PPP.
debug ppp authentication - يسبب الأمر debug ppp لعرض رسائل بروتوكول المصادقة، بما في ذلك عمليات تبادل الحزم لبروتوكول المصادقة المتباينة (CHAP) وعمليات تبادل بروتوكول مصادقة كلمة المرور (PAP).
هنا، يمكننا إختبار وظيفة النسخ الاحتياطي باستخدام أوامر إيقاف التشغيل وno shutdown على الواجهة التسلسلية على الجانب البعيد. ويؤدي ذلك، بتوافق الآراء، إلى إختفاء المسار الرئيسي لبروتوكول الإنترنت إلى شبكة الوجهة المعنية.
