==Slides and Assignments==
You can find all the slides and assignments on the '''[[/coursematerials|Slides and Assignments]]''' page.

=Assessments=
Each Semester consists of several chapters at the end of each chapter you will find a small quiz(10 questions). This is however not one of the chapter assessments.<br/>
To find the chapter assessments please logon to '''cisco.netacad.net'''. On your '''student home''' page choose the '''class''' and select '''"Take Assessment"'''.<br/><br/>
At the end of every semester you need to complete a Final Exam, this Exam will include questions from all the chapters. And you need to complete this to advance to the next semester.<br/><br/>
'''During the assesments/tests/exams you are not permitted to access the learning materials, teamwork, the internet or other aids.'''

=Meetings=
The main portal for Virtual Meetings and Virtual Classrooms is [http://live.mercantec.dk live.mercantec.dk]<br/><br/>
The Meeting system is based upon Adobe Connect, and will install the client the first time you logon to a meeting.<br/>
[https://seminars.adobeconnect.com/_a227210/vqs-participants/ Quick start guide for participants (PDF)]
==Virtual Meeting Best Practise==
Here is a guideline to help ensure a successful experience both for you, the host and your fellow attendees.
*Run the [http://live.mercantec.dk/common/help/en/support/meeting_test.htm System Check] ahead of time
*Arrive at the virtual meeting 5-10 minutes before it starts. If it's the first time using a new meeting system, arrive 15-20 minutes before start time to solve any problems.
*Place yourself in quiet surroundings, to avoid your headset from picking up background noise.
*Run the audio setup wizard if you change headset, to make sure it's configured correctly.

==Recordings==
All the Meetings will be recorded and added to this section of the page.

===== Eigrp Troubleshooting =====
'''User EXEC Mode'''
*show ip eigrp interfaces
*show ip eigrp neighbors
*show ip eigrp topology
*show ip eigrp traffic
*clear ip eigrp neighbors
*debug ip eigrp [packet | neighbors]

EIGRP show interfaces commands:
<source lang="cli">
Router#<input>show ip eigrp interfaces</input>
</source>

EIGRP show neighbors commands:
<source lang="cli">
Router#<input>show ip eigrp neighbors</input>
</source>

EIGRP show topology commands:
<source lang="cli">
Router#<input>show ip eigrp topology</input>
</source>

EIGRP show traffic commands:
<source lang="cli">
Router#<input>show ip eigrp traffic</input>
</source>

EIGRP clear neighbors commands:
<source lang="cli">
