Also called Link Aggregation Group.

Terms in this definition
- Logical
Independent of any implementation. Each logical design is made real through a physical counterpart.
- LACP
Link Aggregation Control Protocol: dynamically bonds ESX uplinks to switch port channels, set up as LAGs on a Distributed Switch. Using it when deploying VCF calls for a JSON spec.
- VDS
Virtual switch defined once in vCenter and pushed out to each member host. NSX runs on top of it on VCF host transport nodes.
- 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.
