IF I boot up a switch, and then plug in routers (all defaults)
It takes 30 seconds to FWD, per debug spanning-tree events.
So it seems max age is only used when a soluble bpdu stops being sent, and
20 seconds passes.

It was my question and Scott Moriss s answer was that startup time is
(maxage + 2*fwddelay) = 50s
In your case, auusuming you are using STP (in RSTP where is no listing),
you can use maxage= 10s and fwddelay = 2s
Is it true Scott?
thanks

Hi Scott
I have no idea how the archives work. I guess what Im saying is check
about this recently. I think the 14 second thing on switches was covered
by Scott Morris just a week or two ago.
Regards
Gary
