ASK THE EXPERTS - NEW ACCESS SWITCHING PRODUCTS

Welcome to the Cisco Networking Professionals Ask the Expert conversation. This is an opportunity to learn updates on new access switching products Catalyst 2k-S and 3k-X with Cisco expert Tom Zingale.  Tom has worked as a product manager for switching, IOS software, network management and was also a software test engineer.  He has been with Cisco for just over 14 years. He is now a senior product manager in the ethernet switching technology group for the Catalyst 2k and 3k product lines.  Before joining Cisco, Tom worked at various companies as a network engineer and network administrator.

Remember to use the rating system to let Tom know if you have received an adequate response.

Tom might not be able to answer each question due to the volume expected during this event. Our moderators will post many of the unanswered questions in other discussion forums shortly after the event. This event lasts through May 7, 2010. Visit this forum often to view responses to your questions and the questions of other community members.

Hi Tom,

Why these new 2k-S and 3k-X switches ?

The main driver was to add functionality and innovation to the Catalyst 2k and 3k

product lines.

With the release of the the 2960S, Cisco has "rolled" two other selling-not-so-well models into the new 2960S, namely:  2350 and the 2975.

One of the selling points of the 2350 is the 10Gb support.  The downside of this model is that it comes in one flavour only:  48-port.   The selling point of the 2975 is the support for stacking and PoE.  The down-side is again, a 48-port only variety.

With the release of this model, I don't want to fathom what will happen to both the 2350 and 2975.

Re: ASK THE EXPERTS - NEW ACCESS SWITCHING PRODUCTS

Can the 2K-s and 3k-x be

stacked together

New Member

Re: ASK THE EXPERTS - NEW ACCESS SWITCHING PRODUCTS

No the 2k and 3k cannot be stacked together. The Catalyst 3k product line uses Stackwise or Stackwise+ functionality with 64Gb throughput and the 2960-S uses the new FlexStack stacking cabling and functionality.  FlexStack is an entry level stacking technology with 20G througput.   The good news is Stackwise and FlexStack share the same IOS configuration making FlexStack easy is to implement for a user that is familar with StackWise.

Re: ASK THE EXPERTS - NEW ACCESS SWITCHING PRODUCTS

I saw on the datasheet of 2960-s that Switching bandwidth is much bigger than the Forwarding bandwidth, what is the difference between both? Anything to do with the speed with all switches stacked?

Re: ASK THE EXPERTS - NEW ACCESS SWITCHING PRODUCTS

There is a footnote in the datasheet that attempts to explain this at the bottom of the table but I guess it is not helping.

The switching bandwidth is the total switching capacity of the switch- bi-directional. The

forwarding bandwidth is the actual  forwarding capacity of the forwarding hardware. The forwarding bandwidth is really a more appropriate performance measurement.  The 2960-S does support 88G forwarding .  .  The switch is line rate with low latency. There is an error in the datasheet that will be corrected soon, it currently  shows 32G

Hi Tom,

We've been trying to get a straight answer from our authorized reseller about the availability and pricing of the 3750X.  Unfortunately I don't have a very good answer.  Would you happen to know when can I start ordering the 3750X?  We desperately need a date to get the design component off our back.

Re: ASK THE EXPERTS - NEW ACCESS SWITCHING PRODUCTS

The 3750-X is not available yet.  We will have a better understanding of release date in the near future.   You should check with your reseller in mid May

Thanks Tom.  (+5)

I hope this schedule doesn't get pushed back.
