تحريت EtherChannels على مادة حفازة 9000 مفتاح

المقدمة

يصف هذا وثيقة كيف أن يفهم واستكشاف أخطاء EtherChannels على مادة حفازة 9000 sery مفتاح.

المتطلبات الأساسية

المتطلبات

توصي Cisco بأن تكون لديك معرفة بالمواضيع التالية:

• بنية المحولات Catalyst 9000 Series Switches
• بنية برنامج Cisco IOS® XE
• بروتوكول التحكم في تجميع الارتباطات (LACP) وبروتوكول تجميع المنافذ (PAgP)

المكونات المستخدمة

تستند المعلومات الواردة في هذا المستند إلى إصدارات المكونات المادية التالية:

• Catalyst 9200
• Catalyst 9300
• Catalyst 9400
• Catalyst 9500
• Catalyst 9600

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 قيد التشغيل، فتأكد من فهمك للتأثير المحتمل لأي أمر.

معلومات أساسية

يرجى الرجوع إلى ملاحظات الإصدار الرسمية من Cisco وأدلة التكوين للحصول على معلومات حديثة حول القيود والقيود وخيارات التكوين والتحذيرات بالإضافة إلى أي تفاصيل أخرى ذات صلة حول هذه الميزة.

توفر EtherChannel روابط عالية السرعة تتحمل الأخطاء بين المحولات والموجهات والخوادم.  أستخدم EtherChannel لزيادة النطاق الترددي بين الأجهزة، ونشره في أي مكان في الشبكة حيث يحتمل حدوث أختناقات. توفر EtherChannel إستعادة تلقائية لفقدان إرتباط، فإنها تعيد توزيع الحمل عبر الارتباطات المتبقية. إن يفشل خطوة، EtherChannel يعيد حركة مرور من ال failed خطوة إلى بقية خطوة في القناة دون تدخل.

يمكن تكوين EtherChannels بدون تفاوض أو تفاوض ديناميكي باستخدام دعم بروتوكول تجميع الارتباطات، إما PAgP أو LACP.

عند تمكين PAgP أو LACP، يتعرف المحول على هوية الشركاء وقدرات كل واجهة. ثم يقوم المحول بتجميع الواجهات بشكل ديناميكي بتكوينات مماثلة في إرتباط منطقي واحد (قناة أو منفذ تجميع)، ويقوم المحول على مجموعات الواجهة هذه على قيود الأجهزة والإدارة ومعلمة المنفذ.

علامات LACP

يتم إستخدام علامات LACP للتفاوض على معلمات قناة المنفذ عند وصولها. ألق نظرة على معنى كل علم:

القيمة المتوقعة لعلامات LACP هي 0x3D (hex) أو 011101 (ثنائي) للوصول إلى حالة P (مضمن في قناة الميناء).

.... ...1 = LACP Activity (less significant bit)
.... ..0. = LACP Timeout
.... .1.. = Aggregation
.... 1... = Synchronization

...1 .... = Collecting
..1. .... = Distributing
.0.. .... = Defaulted
0... .... = Expired (most significant bit)

التحقق من عملية LACP

يوضح هذا القسم كيفية التحقق من الحالة والعملية الصحيحة لبروتوكول LACP.

فحوصات أساسية

فحصت مخرجات LACP باستخدام الأوامر التالية:

show lacp sys-id
show lacp <channel-group number> neighbor
show lacp <channel-group number> counters
show interfaces <interface ID> accounting 
debug lacp [event|packet|fsm|misc]
debug condition <condition>

يعرض إخراج الأمر الأول معرف نظام المحول وأولويته (ل LACP).

switch#show lacp sys-id
32768, f04a.0206.1900 <-- Your system MAC address

تحقق من تفاصيل جار LACP، مثل وضع التشغيل ومعرف تطوير النظام المجاور وأولويته.

تصحيح الأخطاء

عند عدم وجود مزامنة LACP أو عند عدم تشغيل النظير البعيد ل LACP، يتم إنشاء رسائل syslog.

مكنت LACP تصحيح مع الإستعمالمن هذا أمر:

debug lacp [event|packet|fsm|misc]

إذا قمت بالتركيز على أهم سطرين من تصحيح أخطاء LACP، فهناك بعض المفاهيم التي تستحق تعريف بعض مفاهيم وحدات توزيع الطاقة (PDU) ل LACP.

ملاحظة: القيم التي يتم رؤيتها في تصحيح الأخطاء هي قيم سداسية عشرية. لقراءة القيم بشكل صحيح، يجب ترجمتها إلى أنظمة عشرية أو ثنائية.

أدوات المنصات

يوضح هذا الجدول الأدوات والميزات المتاحة للمساعدة في فهم متى يتم إستخدامها:

ملاحظة: يتم تحليل بروتوكول LACP فقط باستخدام هذه الأدوات، ومع ذلك، يمكن إستخدامها أيضا لتحليل إطارات PAgP.

التقاط الحزمة المضمنة (EPC)

الأوامر الخاصة بإعداد Wireshark (EPC) والتقاط وحدات توزيع الطاقة (PDU) الخاصة ببروتوكول التحكم في الوصول إلى شبكة الاتصال (LACP) من خلال المدخل/المخرج.

ملاحظة: يتم إدخال الأوامر ضمن وضع الامتياز.

إعداد التقاط Wireshark.

تلميح: إذا كنت تريد التركيز على واجهة مدمجة معينة و/أو عنوان MAC محدد المصدر، قم بضبط الواجهة ومطابقة كلمات MAC الأساسية.

monitor capture CAP interface GigabitEthernet1/0/4 BOTH
monitor capture CAP match mac any host 0180.c200.0002  
show monitor capture CAP file location flash:CAP.pcap

ملاحظة: يساعدك معرف عنوان MAC للوجهة 0180.c200.002 على الالتقاط على تصفية إطارات LACP.

تحقق من تكوين Wireshark بشكل صحيح:
