3 hands-on LLDP scenarios you build in your own Cisco Modeling Labs instance and grade against the answer key. Focused LLDP configuration and troubleshooting practice for CCNA and CCNP.
Harden Cisco IOS edge interfaces by disabling CDP/LLDP toward untrusted endpoints while keeping discovery active on trusted infrastructure links. Routers share a management LAN with a server and form a direct router-to-router adjacency for CDP/LLDP. The learner enables discovery globally, selectively suppresses it on the client-facing edge, and verifies the outcome with show commands.
Enable the open-standard LLDP on adjacent Cisco IOS routers over direct point-to-point links while also attaching the devices to a shared management LAN. Learners configure deterministic LLDP behavior (global enable plus per-interface transmit/receive) and verify neighbor discovery without adding any routing protocols or static routes.
Troubleshoot a pre-broken monitoring deployment on a single shared management LAN. R1 is already configured for discovery and monitoring, but the NMS receives no syslog or SNMP traps from R1. Diagnose with show commands and correct the two seeded faults: wrong syslog target and missing SNMP trap generation. Deterministic, no-routing, single-subnet design for CML Free (5 nodes).
