Linux OSI Layers
 

Guys, let me know if you can help me with this question:

Identifying the Function of Each OSI Layer
The users of the network report that they can’t reach systems
on the other side of a new switch. Which layer is the likely
place where communication is failing?
(Assuming that the cabling infrastructure, end-user systems,
and network interface cards (NICs) have not been changed)?

Thanks

linuxquestions is not a site for homework. if you are set questions you are meant to work them out yourself, that's the point.

Yo, I'm getting this question from a book that doesn't have answers, and now you're telling that this is a question for a hw? I'm not even going to school, so I guess you should ask first before making those statements. If you can't help, just ignore my post

What application is failing?
What Kind of switch?
Do you have a link light?
Can users ping other hosts?

whether it's homework or not, you're the one reading the book and therefore you're the one who should be able to solve the problem.

just because a book doesn't have answers doesn't mean you can't work it out for yourself. i'd thank you not to tell me not to reply. posting homework questions goes against the rules you have agreed to. I am a moderator. I moderate. If your question is out of genuine interest then fair enough, but rules are rules.

MelLinux. Our moderator, Chris, is correct. He has a link under his name to a site that is well worth the read. His "How to ask good questions - please read!" link ought to be mandatory reading for all of us--I know I just learned a heck of a lot from it.

I have a feeling this is only going in the wrong direction now, so this thread is being closed.

But I have to admit, just because a book has questions, doesn't mean you can't figure them out on your own. That's like having a test with the answers on the back, how are ya ever gonna learn. Might not have the answers for you in the back, but they should be in that book somewhere, or they wouldn't ask it..

Okay, that was my 2 cents on the subject which is now the last also.

Almost last Drew ;)

MelLinux,
I would guess that Chris thought you were trying to use LQ to do your homework (and I would have agreed with him) as the question is clearly verbatim out of a book. If after reading the book you have a specific question about something you do not understand feel free to ask for clarification or an explanation - I think your results will be much better.
