Re: Network Design

Look Friends it depends means that you can do many things but what I know
and what actually I see in my real life not all companies got a good amount
of budget to get enough infrastructure I mean the Hierarchical Modular
Design Plus when you are studying the technology you are getting the end of
it but maybe you will face this once in your life and maybe never.

also there's a big Guide lines on designing a networks already you answered
them in your question that you choose the 3750's to be you access ? well,
tell me why you chooses this one ?! because its small box. well I thing as
engineer you answer no but it not that strong Platform to hold the all
network operations.

also its the same concept as private-vlans and vlans; they are almost the
same with some extra security features belongs to private-vlan [port modes
I mean], most of people I met in my life when you say about private vlans,
you just big ? on their face and they got afraid from this feature is that
means that I can't reach the Goal with normal vlans. well It Depends here
you are every place every environment got its own goals infrastructure so
as a good designer you still need to know the business needs and goal and
if there's a network outage what is the effect and calculate the risks and
create a back automated solutions to meet the HIGH AVAILABILITY which is
called in the hierarchical modular design.

I have worked on banking and partner and exchange market
and transportation they are all using almost the same devices it differs on
some two 3 platform as Core switched but at the same technology different
design so here what It depends mean.

at the end there's always an access layer and core layer most of time no
distribution layer because the network is little small and
some companies uses 4500 Switch as a core and other uses 6500's switches at
the end they are core layer but why you chooses this not that because it
depends.

and this why all the people here spend their life to learn and this why we
stay the all night studying reading because it depends and at the end of
the day I am the engineer the management they just care for total amount so
you have to be knowing what you are choosing and buying because you are the
one who will be responsible for to troubleshoot and operate on it.

sorry for my long mail but your question i was asking to my self from 3
years and I found this answer by my self.
