تصحيح أخطاء وضع IPSec و IKE - أستكشاف أخطاء وضع IKEv1 الرئيسي وإصلاحها

المقدمة

يوفر هذا المستند معلومات لفهم تصحيح الأخطاء على برنامج Cisco IOS^® عند إستخدام الوضع الرئيسي والمفتاح المشترك مسبقا (PSK).

يوفر هذا المستند أيضا معلومات حول كيفية ترجمة بعض خطوط تصحيح الأخطاء في تكوين ما.

هذه الموضوعات غير مطروحة للنقاش:

• تم إنشاء حركة مرور بعد النفق
• المفاهيم الأساسية ل IPSec أو تبادل مفتاح الإنترنت (IKE)

مسألة أساسية

تميل تصحيحات IKE و IPSec إلى أن تصبح مشفرة. غالبا ما يستخدم مركز المساعدة التقنية (TAC) من Cisco هذه الأخطاء لفهم موقع مشكلة في إنشاء نفق VPN ل IPSec.

سيناريو

عادة ما يتم إستخدام الوضع الرئيسي بين أنفاق الشبكة المحلية (LAN) إلى الشبكة المحلية (LAN)، أو في حالة الوصول عن بعد (ezVPN) عند إستخدام الشهادات للمصادقة.

هذه تصحيح الأخطاء من جهاز Cisco IOS الذي يشغل إصدار برنامج 15.2(1)T.

تم وصف سيناريوهين رئيسيين في هذا المستند:

• جانب بادئ IOS
• جانب المستجيب IOS

في هذا المستند، يتم إنشاء نفق يستند إلى VTI بين موقعين، استنادا إلى IPv6.

ملاحظات:

أستخدم أداة بحث الأوامر (للعملاء المسجلين فقط) للحصول على مزيد من المعلومات حول الأوامر المستخدمة في هذا المستند.

ارجع إلى معلومات مهمة عن أوامر تصحيح الأخطاء قبل أن تستخدم أوامر debug.
