LLDP Overview The Link Layer Discovery Protocol (LLDP) does the same thing as CDP, but it is not specific to Cisco devices. As a bonus, you can still use it if you have Cisco devices. One way or another, you will get your network map.
LLDP is a vendor-neutral neighbor discovery protocol similar to CDP. LLDP works with network devices, such as routers, switches, and wireless LAN access points. This protocol advertises its identity and capabilities to other devices and receives the information from a physically-connected Layer 2 device.
