Local Area Network Essentials
Run by School of Computer Science and Electronic Engineering
20.000 Credits or 10.000 ECTS Credits
Organiser: Dr David Edward Perkins
Overall aims and purpose
This module predominantly uses the “Switching, Routing, and Wireless Essentials” section of the Cisco CCNA course and focuses on switching technologies and router operations that support small-to-medium business networks and includes wireless local area networks (WLAN) and security concepts.
Students learn key switching and routing concepts. They will perform basic network configuration and troubleshooting, identify and mitigate LAN security threats, and configure and secure a basic WLAN. The theoretical content of this module is blended with a substantial number of practical exercises involving configuration of switches and routers. These exercises are carried out either in a networking lab using industry standard hardware or using the Cisco Packet Tracer network simulator which is provided to all students studying the Cisco based modules to facilitate practice at home.
Indicative content includes:
● Switching concepts. Collision domains, broadcast domains, frame forwarding, ● Virtual LANs (VLANs). VLAN trunking, Dynamic Trunking Protocol (DTP), native VLANs, 802.1Q tagging, Voice VLANs, VLAN attacks, inter-VLAN routing ● LAN redundancy. Spanning Tree Protocol (STP). First-hop Router Protocols (FHRPs). Etherchannel. ● Address allocation. DHCPv4. SLAAC & DHCPv6. ● LAN security concepts. Configuring switch security. ● Wireless LANs (WLANs). WLAN concepts. WLAN configuration. ● Routing. Packet forwarding, routing decisions, routing table, directly connected routes, static routes, default routes, summary routes, floating static routes, dynamic routing protocols (distance-vector v. link-state), RIPv2
Equivalent to the range 70%+. Assemble critically evaluated, relevent areas of knowledge and theory to constuct professional-level solutions to tasks and questions presented. Is able to cross-link themes and aspects to draw considered conclusions. Presents outputs in a cohesive, accurate, and efficient manner.
Equivalent to 40%. Uses key areas of theory or knowledge to meet the Learning Outcomes of the module. Is able to formulate an appropriate solution to accurately solve tasks and questions. Can identify individual aspects, but lacks an awareness of links between them and the wider contexts. Outputs can be understood, but lack structure and/or coherence.
Equivalent to the range 60%-69%. Is able to analyse a task or problem to decide which aspects of theory and knowledge to apply. Solutions are of a workable quality, demonstrating understanding of underlying principles. Major themes can be linked appropriately but may not be able to extend this to individual aspects. Outputs are readily understood, with an appropriate structure but may lack sophistication.
