CDP and LLDP
Used Cisco Discovery Protocol (CDP) to map out a multi-device network topology, then transitioned to Link Layer Discovery Protocol (LLDP) to accommodate multi-vendor environments by enabling transmit and receive on relevant interfaces.
Tools:- Cisco Packet Tracer
- Router CLI
- Switch CLI
- CDP Show Commands
- LLDP Configuration Commands
- IPCONFIG Command
- Interface Status Command
Skills Demonstrated:- Using CDP to discover directly connected Cisco devices
- Mapping network topologies by analyzing CDP neighbor and interface status
- Identifying and labeling interfaces using CLI commands
- Disabling CDP selectively on end-device interfaces
- Enabling LLDP globally and per-interface on Cisco devices
- Understanding LLDP’s role in multi-vendor environments
- Practicing interface-based discovery with LLDP show commands
- Configuring transmit and receive settings for LLDP interfaces
- Interpreting MAC address tables and interface states
