(In reply to weberge42 from comment #12)

> each switch has different default and miniumum values

Yes, and one should not depend on default values but configure switches as
required.

> But what if you can't (or not allowed) to change this settings ?

Too bad for you if you have manageable equipment but can't manage it.

> I just don't see any relationship between manual ifconfig in case of a failover. Can you please elaborate this a bit more ? Maybe i'm missing something.

In case of "non-manual" failure physical link goes down generally and
corresponding switch changes its FIB at once.

If one connects redundant layer-2 links to different switches, one should use
some kind of signalling protocol like RSTP.
