-Such is true, and from what I can tell you both are right. In my
experience, a Win box will not respond to a ping if there is not layer1
connectivity, while a Solaris box will. Why?.. I don't know. Solaris seems
to
associate the interface with a name first and then with an IP, while Win is
the other way around. Any protocol gurus there??, Priscilla, any input??
(aside: I read your book to pass my CCDA two years ago, still one of my
favorites. I've got a crush on you don't ever change I will be your groupie
if you want one xoxoxo) plus you are one of
the best contributors to this list! I don't agree that the OS does not care
about layer1, if you don't have a link on a windoze box, you will NOT be
able to ping it locally NO HOW NO WAY see. Hmm... alright how many CCNA's
does it take to change an IP address on a PC?
Ten, one to do it and nine to bitch that it is not their a job, a MCSE
should handle it. Long live the acronyms.
