CDP and LLDP Discovery Mapping
Learn to discover what is actually connected before changing configuration or troubleshooting blind.
Lab challenge
Reconstruct the physical topology using discovery protocols and verification output instead of guesswork.
Progression
Collect neighbor data, correlate local/remote ports, clean up any unneeded advertisements, and document the result.

Prerequisites
- • show command basics
Skills practiced
- • enable LLDP where needed
- • inspect CDP neighbors
- • map physical links
- • disable discovery on untrusted edges
Validation checklist
- • neighbor IDs and ports match the topology
- • learner produces a correct cable map
- • discovery is disabled on at least one edge where appropriate
Task sequence
- 1View CDP neighbors and detailed entries.
- 2Enable and verify LLDP if the platform requires it.
- 3Map local interfaces to neighboring ports.
- 4Disable discovery on one edge interface where disclosure is unnecessary.
- 5Produce a final cable map.
