Objectives
- What QoS is and why it's important in enterprise networks
- Key QoS concepts like classification, marking, queuing, policing, and shaping
- Step-by-step configuration of QoS using commands on both switches and routers
- Traffic classification using access control lists (ACLs) and class maps
- Marking and prioritizing traffic using DSCP and CoS values
- Implementing traffic queuing strategies such as Low Latency Queuing (LLQ), Weighted Fair Queuing (WFQ), and Class-Based Weighted Fair Queuing (CBWFQ)
- Understanding how to manage and monitor different queues to ensure efficient traffic handling
- Configuring traffic policing to enforce rate limits and traffic shaping to smooth traffic bursts
- Real-world examples of configuring policing and shaping on interfaces to control bandwidth usage
- Implementing advanced QoS techniques like Network-Based Application Recognition (NBAR) to dynamically classify and prioritize applications
- Using AutoQoS to automate QoS configurations on switches and routers
- Troubleshooting and monitoring QoS implementations to ensure optimal performance
Pre Requisites
- Basic understanding of networking concepts (IP addressing, subnets, etc.).
- Enthusiasm to engage in lab-heavy, hands-on learning.
- Access to a computer with internet connectivity.
- Familiarity with Cisco IOS commands is helpful but not required.
- Interest in learning practical Cisco configurations.
- A desire to improve network configuration and troubleshooting skills.
FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
