A vendor-neutral protocol that network devices use to advertise their identity to directly connected neighbours, revealing which switch port a link is plugged into; Cisco's CDP does the same job. In vSphere it is offered only on distributed switches.
Also called Link Layer Discovery Protocol.

Each book explains LLDP in context, with comparison tables and the common traps.
Terms in this definition
- IDENTITY
A column property, written IDENTITY(seed, increment), that gives each new row the next number in a rising sequence. SCOPE_IDENTITY reports the latest value created in the current scope, and a rolled-back transaction still uses up the numbers it took.
- SWITCH
Checks one expression against several candidate values, returning whichever result pairs with the match (or a fallback otherwise). Writing SWITCH ( TRUE (), ... ) avoids nested IF chains: whichever condition is first true wins.
- CDP
Cisco Discovery Protocol lets an administrator see which port on a physical switch each host uplink is cabled to. vSphere supports it on distributed and standard switches alike, while LLDP requires a distributed switch.
- Job
A sequence of steps executed together on one agent or runner, or on the server for agentless work. While running, each occupies one of your parallel jobs.
- vSphere
VMware's platform for virtualisation, made up of vCenter and ESX hosts, supplying compute for VCF clusters.
