Summary of Content

This module aims to provide students with the theoretical knowledge and practical skills needed to determine appropriate design choices for layer 2 network solutions, implement them and verify their operation.


LAN Switching Technologies Implement and troubleshoot switch administration (Managing MAC address table, errdisable recovery, L2 MTU). Implement and troubleshoot layer 2 protocols (CDP, LLDP, UDLD). Implement and troubleshoot VLAN (access ports, VLAN database, normal, extended VLAN, voice VLAN). Implement and troubleshoot trunking (VTPv1, VTPv2, VTPv3, VTP pruning, dot1Q, Native VLAN, Manual pruning). Implement and troubleshoot etherchannel (LACP, PAgP, manual, layer 2, layer 3, load-balancing, etherchannel misconfiguration guard) Implement and troubleshoot spanning-tree (PVST+/RPVST+/MST,switch priority, port priority, path cost, STP timers, port fast,BPDUguard, BPDUfilter, loopguard, rootguard). Implement and troubleshoot other LAN switching technologies SPAN, RSPAN, ERSPAN Troubleshooting layer 2 technologies Use IOS troubleshooting tools (debug, conditional debug, ping, traceroute with extended options, Embedded packet capture). Apply troubleshooting methodologies (Diagnose the root cause of networking issue (analyze symptoms, identify and describe root cause), Design and implement valid solutions according to constraints, Verify and monitor resolution). Interpret packet capture (Using wireshark trace analyzer, Using IOS embedded packet capture).

Learning Outcomes

On completion of this module, students should be able to:- critically analyze layer 2 technologies and determine appropriate design choices based on this analysis.- evaluate the workings of layer 2 technologies at an advanced level.- compare different design cases in Campus infrastructure and justify design choices.- select from the techniques and tools presented to implement switch configurations;- critically analyse complex problem scenarios and deploy appropriate solutions;- evaluate the correct operation of layer 2 networking technologies and solutions- assess and fix complex layer 2 networking issues using common commands and diagnostic tools.

Teaching / Learning Strategy

The course will be presented as a programme of lectures supported by tutorials and associated practical work. Students are directed to read appropriate texts and articles to consolidate their knowledge of the topics covered.
