An airport authority must inventory mixed-vendor cameras on access ports and wants standards-based neighbor discovery rather than a Cisco-only protocol. Which approach fits?
Select an answer to reveal the explanation.
Short Explanation
Mixed-vendor gear is a multilingual lobby—Cisco-only CDP is one dialect. LLDP is the common language on the doorplate. Turn it on at the access edge when cameras and other non-Cisco gear must announce who they are.
Full Explanation
LLDP (IEEE 802.1AB) is the standards-based neighbor discovery protocol and works across vendors that implement it, while CDP is Cisco proprietary and often missing on third-party cameras. UDLD detects unidirectional links and does not replace discovery for inventory. DHCP leases show addresses, not Layer-2 adjacency and capability TLVs. For multi-vendor access-port inventory, prefer LLDP and keep CDP only where Cisco-centric visibility still helps.
