Cisco Networking: Trunks, VLANs, CDP, LLDP, UDLD

This workbook serves as a comprehensive guide for configuring and validating essential Cisco Layer 2 switching technologies. It focuses on key areas, including VLANs, trunk configurations using 802.1Q, and the Layer 2 discovery protocols CDP and LLDP. Additionally, it covers UDLD (Unidirectional Link Detection) for link reliability and troubleshooting.

Each section provides step-by-step configurations, command-line examples, and validation tips, making it ideal for networking professionals and students seeking to deepen their practical knowledge in a hands-on lab environment.

The primary goal of this workbook is to equip learners with a solid understanding of Cisco Layer 2 switching technologies and their practical applications in network environments. By engaging with the content and exercises provided, participants will achieve the following objectives:

Understand VLAN Concepts: Participants will grasp the significance of VLANs in network segmentation and learn how to create, manage, and configure VLAN interfaces.

Configure Trunk Links: Learners will gain the skills necessary to configure trunk links using 802.1Q, differentiating between access and trunk ports to ensure proper VLAN tagging and traffic management.

Validate Configurations: Throughout the workbook, learners will develop the ability to validate configurations using relevant commands and techniques, ensuring that all implemented technologies function as intended.

By the end of this workbook, participants will be well-prepared to apply their knowledge of Layer 2 switching technologies in real-world scenarios, enhancing their skills as networking professionals.
