Schedule

Learning outcomes

The graduate of the course will learn the basic components, architectures and operation of routers and switches in small networks, also become familiar with the functionality of wireless local area networks (WLAN) and the associated security concepts. Students will learn how to configure and troubleshoot routers and switches for advanced functionality using security best practices and how to resolve common protocol issues in both IPv4 and IPv6 networks. The graduate is able to configure functionality such as: VLAN and Inter-VLAN routing using security best practices, troubleshoot inter-VLAN routing issues on devices operating at the network layer of the ISO/OSI model (L3), configure redundancy in a switched network using STP and EtherChannel, troubleshoot EtherChannel issues in switched networks, configure dynamic address allocation in IPv6 networks, configure WLANs using WLC and L2 security best practices, configure switch security to mitigate LAN attacks, and also configure static IPv4 and IPv6 routing on routers.

Course outline

1. Basic configuration of routers and switches, remote access provisioning and verification of directly connected networks. 2. The role of switching concepts in data networks, forwarding L2 frames, collision and bradcast domains. 3. Virtual LAN (VLAN) concept, functionality of trunking and access ports, dynamic trunking protocol DTP. 4. Inter-VLAN routing, Router-on-Stick routing and also VLAN routing based on L3 switches. 5. Purpose, operations and evolution of STP protocol for loop-free switched networks. 6. Operations, configuration and verification of EtherChannel technology functionality. 7. Working with dynamic allocation of network settings (DHCPv4, DHCPv6, and SLAAC). 8. Familiarity with the concept of FHRP, which provides default gateway services in a redundant network. 9. LAN security concepts, access control using ACLs, attacks in LANs, port security implementation. 10. introduction to wireless WLANs, CAPWAP operations, WLAN security mechanisms. 11. Static routing issues, configuration of fixed and floating static routes, gateways and routing of user traffic. 12. IPv4 and IPv6 packet processing. Advanced diagnostics and troubleshooting of common routing problems.

Completion conditions

Assessment and completion of the course: Credit test and examination Continuous assessment: Student passes the continuous assessment and receives credits when he or she meets the requirement to obtain at least 21% out of 40%. Continuous tests will be carried out to verify the acquired knowledge. During the semester, students will work on assignments on the subject. Final assessment: Student passes the final assessment and passes the examination when he or she meets the requirement to obtain at least 31% out of 60%. A minimum of 51% on the interim assessment and 51% on the final test will be required to pass the course. The overall grade will be determined by the total number of points earned on the midterm assessment and the final test score. Overall assessment: Overall assessment is the sum of the assessments obtained by students in the assessment period. The overall result is determined in accordance with the internal regulations of the Technical University in Košice. (Study Regulations, the internal regulation principles of doctoral studies)
