CCIE Enterprise - Quality of Service Lab - Initial + Full Configs

Quality of Service (QoS) mechanisms prioritize network traffic to ensure optimal performance for critical applications. QoS operates by classifying traffic based on various criteria, such as source/destination IP addresses, port numbers, or application type.

Once classified, traffic is marked using techniques like DSCP (Differentiated Services Code Point) or 802.1p, allowing network devices to identify and apply appropriate policies. These policies can include prioritization (giving preference to critical traffic), bandwidth allocation (reserving a specific amount of bandwidth), congestion management (using algorithms like Weighted Fair Queuing or Low Latency Queuing to manage congestion), and traffic shaping (controlling the rate of traffic entering the network).

Effective QoS implementation requires careful planning and configuration, considering factors like network topology, application requirements, and available bandwidth. Furthermore, monitoring and analysis of QoS metrics are essential to ensure that policies are effective, and adjustments can be made as needed.

In this lab you will practice these tasks:

• Classifying traffic
• Marking traffic
• Policing and shaping
• working with queues

The default username and password for images used in this course is as follows, however you will hear new passwords during the course if the instructor changes the credentials: 

** For Cisco XRv you are asked for a username and password in the loading process. You can add any username and password other than admin, root, sysadmin and other reserved usernames. Go with something like Alex/cisco e.g.

Then when completely loaded, you can use cisco/cisco or admin/admin.

***For XRv9K Full image you are asked for a username and password in the loading process. You then login using the username and password that you set.
