At the link layer, this certainly makes sense to me. It would IMO be useful to have something to bring links administratively down with dladm. Also, what I've thought about in the past is that (if done right) this could help with the usability of DR by allowing hardware to be replaced while a link is administratively down without having to unplumb any IP interfaces of stop applications that are using the link. The link state simply goes down during the DR operation. This also helps by circumventing the wacky cfgadm hardware namespace that no-one understands. This may be a slight digression, my only point is that I see value in an administrative up/down at the datalink level, and this may address what you describe above. This may not necessarily be a requirement for IP interfaces. -Seb _______________________________________________ networking-discuss mailing list [email protected]
