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
