As a piece of network equipment, for a network engineer/administrator, LLDP is an indispensible tool for managing and troubleshooting a network. It's almost surprising that I would have to explain how incredibly useful it is, since every other major wifi network equipment manufacturer recognizes this and supports it. Devices which support LLDP will show up on a switch stating what they are (phone, switch, router, WAP, etc), what their IP address is, what their host name is, their firmware revision, manufacturer, etc. This is extremely helpful when you are trying to track down a device that isn't reachable, has failed a firmware update, isn't showing up on an expected port, etc. An incorrect IP address on a WAP means that somehow it got hard coded with a bad IP and may need to be set to factory defaults. A WAP that no longer shows up on the ZoneDirector that shows up on a port that isn't untagged in the native VLAN just needs to have the port reconfigured or be moved to the right port. The list goes on and on. It's a tool that greatly simplifies and speeds up troubleshooting.
