TAC
acronymnetworkingops culture
The vendor's technical assistance centre: the engineers you reach when a product itself, rather than your configuration of it, may be at fault.
Opening a TAC case is a handover, and it succeeds or fails on the same things any handover does: what was reported, what has been established as true, what was ruled out and how, and what has already been changed. A case that arrives as “it is broken” gets a reply asking for the things the first message should have carried.
