I never got back to this email and I am sorry I took so long...
1) The 6509 has a 256Mbit backplane capacity.
2) I am not a Cat6500 person, but I thought the Cat6500 Sup's run in
parallel? (Anyone know off hand?)
3) I am not sure what you mean by local switching. The 6500 uses dCEF
(Distributed CEF) where as Extreme uses flow based routing. Most people
don't even know what dCEF is...
4) You are correct. The Catalyst is a layer 2 switch that has routing
abilities with added hardware. Cisco is not the only Vendor that does this.
5) True... But again... Cisco isn't the only company that advertises their
equipment like this. Foundry is a good example. A Cat6500 has 9 slots - 1
Sup. You don't have to put in two Sups. Most people buy two switches...
Another downside to eXtreme is that they only support 10/100/1000 and
Giga-Etherchannel where the 6500 supports those plus T1/E1, T3/E3,
STM/1/4/16, OC3/12/48, ATM & POS, ...etc. Both products are very different
from one another...
If you want to talk about cutting edge, the 6500 OSR uses a new technology
called PXF (Parallel eXpress Forwarding, read below). The eXtreme uses
ASIC's which have fixed functionality with a 12-18 month life cycle. This
is a Cisco engineered technology that wasn't obtained from an acquisition.
This is the first (to my knowledge, so please correct me if I am wrong)
reprogramable ASIC-type processor. Cisco has always been known for
functionally and not speed, and this will be changing soon.

PXF Field Upgradeable
Parallel eXpress Forwarding (PXF) is based on microcode and can be upgraded
with new software features in future IOS releases.
The PXF processor enables IP parallel processing functions that work with
the primary processor to provide accelerated IP Layer 3 feature processing.
The PXF processor off-loads IP packet processing and switching functions
from the Route Processor (RP) to provide accelerated and highly consistent
switching performance when coupled with one or more of several IP services
features such as access control lists (ACLs), address translation, quality
of service (QoS), flow accounting, and traffic shaping.
PXF offers the advantage of hardware-based switching power, plus the
flexibility of a programmable architecture. The PXF architecture provides
future-proofing�if additional features are added in the future, an
application-specific integrated circuit (ASIC) will not be required. New
features for accelerated services can be added by reprogramming the PXF
processor.

Subject: RE: eXtreme ,juniper, Foundary and Cisco
hi Eddie ;
i was waiting someone from cisco to answer the question which i raised
yesterday ,i love to work on the Cisco products ..but alas...love is not
enough ...wat Ton of features the Cisco switch has and extreme one doesnt ??
this is a good point to start defeat Cisco against the young guys .
is Cisco in the way to solve their performance problems against extreme ??
some of the problems Extreme usually say against cisco is
1- 6509 is blocking with only 32 G backplane capacity
2- the second Supervisor engine is always in standby mode
3-the network modules cannot do local switching
4- layer 3 features need to add more and more hardware
5- 6509 is NOT 9 slots in fact is only 7
i guess Cisco should have to do something to solve these problems then there
will not be any problem to win ANY project against the young guys
thx

Inamul,
What do you need the switch to do? I am not sure what your application
is, but most enterprises come NO WHERE close to either products switching
ability. I say this not because I work for Cisco, but our switch does a TON
of things the extreme switch doesn't. Ask yourself what features you need
now and also look at the roadmaps (if extreme even offers one) for future
feature.

My company just about to choose Cisco 6509 or EXtreme switch.
We even brought extreme switch for evolution, Cisco could not
deliver test box so we had to go their lab.
Anyway, they both have pros and cons and extreme is way faster
than Cisco with better pricing. With Cisco, even if want to buy it,
we will have to wait till April 2001 as Cisco can not fill in orders
or they do not have any in stock. Cisco is definitely loosing market
share on switching side. I would prefer Cisco cos I am working on
CCNP but wish Cisco could deliver box yesterday like extreme.

You bring up very good points. I would like to add another. I work for an
ISP and there is a lot to be said for a homogenous network. I am familiar
with IOS and as the majority of our network devices are Cisco, I have an
easier time learning new things or figuring out others. Also, it is nice to
be able to go to one source to get answers. I am not necessarily the
biggest fan of Cisco, but going the Cisco route does have major benefits.
FYI, I have used Boson Tests. I find them to be excellent tools for putting
you into the mindset of the exam.

Subject: Re: eXtreme ,juniper, Foundary and Cisco
I'd just like to point out one fact that most enterprises do give a lot of
thought before making purchase decisions - Extreme, Foundry, Juniper, et al
DO NOT have end-to-end solutions. Cisco does.
The former also do not have a trained pool of network engineers to recommend
and implement their products, whereas you'll find plenty of Cisco-trained,
Cisco-experienced network engineers, designers & support professionals.
Cisco IOS offers one consistent interface & CLI throughout most of its
product line. Cisco also offers an impressive range of Network Management
products that we're yet to see from other vendors.
It's an endless debate - but not all enterprise networks require the
performance & capabilities of a Juniper or a Foundry.
Having said that, let me also add that as things stand, by no means is Cisco
technologically the most superior throughout the length & breadth of its
entire prouduct line. Juniper, Extreme, Foundry and others do have their
niches that they fill quite effectively, and pose challanges to Cisco in
those markets.
And as someone correctly pointed out, the basic networking knowledge is
still required even to implement other vendors' products. I doubt the CCIE
will lose its value any time soon, but we just might see a deluge of CCNAs &
CCNPs bred on the ExamCrams, Transcenders & Bosons.
(I'm yet to determine how many of the people on this newsgroup have/have not
used Boson tests... :-)
