3750 at the core of a network?
When you're at the core, then you're talking high-speed switching backbone and should be designed to switch packets as fast(est) as possible.
So, I will base my decision on, first, backplane speed/throughput, and then on cost.
What's the maximum backplane speed out of a 3750? & what's the maximum backplane speed out of a 4500? Assuming the level of setup of stackable 3750s cost the same as the 4500 you're putting in?
Sup6E on 4500 can push bandwidth/throughput up to 320Gbps/250mpps with a linecard speed of 6Gbps.
Whereas 3750G has forwarding rate of 38.7mpps or something using 32Gbps high-speed stacking bus on a stack(stackwise) interconnect technology.
I'm sure there will be other comparisons, but in my own personal opinion, I will pick 4500 over 3750 for core based on speed factor alone. Obviously other issues like size of the campus network you're dealing comes into factor, cost, etc. You sometimes don't have to buy a Ferrari for a job which FiatPunto can do, but I'm sure the design guys will not be too happy with you putting in 3750(traditionally a distribution/access switch) permanently at the core, at least the ones I work with would most def not approve such design.
Many Thanks

Chaps, need your help, I can't decide.....
Is there any advantage in using 4500 switch over stack of 3750 switches at
the core of a network?
appreciate your input.
Thanks
Tajamal

Unbelievable for me, from CCNA to CCIE in 9months! That's really
impressive/awesome. (I assume you're referring to Sept. 2007)
Well done mate, and keep up the good works. Yea, I reckoned with Joseph,
ditch the CCNA, but RHCE still rocks in Linux world though....can't
think of any greater cert in that line, LPI or Linux+? No chance ...
keep RHCE, then ofcourse keep CCIE.
Enjoy!
Many Thanks

Hi everyone,
In my second attempt at Bangalore yesterday, I passed R&S lab. I'd like
to
thank my best gal Swapnita, Brians from IE, Scott Morris, and all the
great
people at groupstudy for their support.
I started my journey back in September when some of my work involved
routing
for SaaS applications, and I enrolled myself in a CCNA class. As the
instructors answered most of my questions with "It's not part of the
CCNA
exam", I decided to go for CCIE. This was the first time I ever touched
a
Cisco router. I passed the written exam in November and after that, used
dynamips for most of the lab preparation.
I came so close to passing in my first attempt, but got a lousy 78%
instead
of a CCIE number. After coming back home, I scheduled another lab after
30
days and worked on my weaknesses. I finished my lab yesterday 30 minutes
after the lunch and had 4 hours to verify everything. Got my result in 4
hours after leaving the lab.
For all lab candicates, I'd like to add a note, IE mock labs and CCIE
Assesor are priceless. Go for them before going to real lab. Also, there
is
no substitute to real knowledge in the lab. You need to know your stuff
well
or else it's just $1400 lunch. And it isn't that great anyways ;)
Time for me to get back to SaaS and Unix. Maybe in a few months I can
party
when I'm old enough to drink :P
