comparison and ping problem

[sakibd2k]

HI,

I am asking might be a fool question but cant stop
myself.
Why will we use cisco router and switches where as we
have linksys , Dlink, Netgear? Is it price?
or might be some extra propreatery feature of cisco
like HDLC for wan or does not STP provided in netgear or Linksys or dlink switches? I dont know whether i asked it correctly does any one got my point?

I have one different question is it possible to ping
suppose two different device in same Vlan when they are not connected with internet? then how? just similar way as we do ping to that assigned ip address?

Forgive my little knowledge.

Hello
What your'e asking isn't a fool question.After years of networking I still ask myself the same question.What I have come to understand is that different companies have shightly different reason.Reliability,features,service contracts,etc.But in the end the real reason is because any serious company will want to go with the number one on the market.It's like anything else in life.If you can afford go with the best.
Your question about the ping isn't very clear.What do you want to achieve?Do you want to ping two devices at the same time?

Regards

Hello,
Thanks for replying. I got answer for my first question somewhat.
Regarding the second one actually i am trying to realize Vlan practically.
As from Vlan concept it says 2 devices in same vlan can talk each other but cannot with other device in other vlan.
for that we have to use router.
So to realize talking i assume they will be ping able.

But i want to set it up without internet connection.
Is that possible?

Again thanks for sharing.

Yes!It's possible having Internet doesn't change the VLAN logic.Remember Internet is an extra feature.In the past and still today some companies don't need Internet to do their bussiness.They only depends on local server on the LAN.
