Catalyst 2960 Stack Capability

Hi,

I have a query regarding Catalyst 2960's ability to be connected in a stack. The 2960 Q&A gives following 2 statements: (http://www.cisco.com/en/US/partner/products/ps6406/products_qanda_item0900aecd80322c37.shtml)

Q. What are dual-purpose uplinks?

A. A dual-purpose uplink is a combination of one 10/100/1000-TX copper port and one SFP-based Gigabit Ethernet port. One of these two ports can be used at a time. This added uplink flexibility allows cost-effective use of high-density, fiber-uplink-based stacks. Dual-purpose uplinks also offer a full-duplex, gigabit-speed trunk for a Cisco Catalyst 2960 Series switch stack, an improvement over the half-duplex Cisco GigaStack® configuration.

Then it goes on and say:

Q. What is the positioning of the Cisco Catalyst 2960 Series relative to the Cisco Catalyst 3560 and 3750 Series?

A. The Cisco Catalyst 3750 and 3560 Series are for fixed-configuration enterprise 10/100 and 10/100/1000 applications. Cisco Catalyst 3750 Series Switches are ideal when a group of interconnected switches requires higher levels of availability, redundancy, performance, and ease of use inherent in Cisco StackWise™ technology.

So my query is that can 2960 support a stack configuration if we want to interconnect the Fiber SFP uplink port of one 2960 to Fiber SFP uplink port ot another 2960...I went through the following link but couldn't find relevant info:-

Any information will be greatly appreciated.

Re: Catalyst 2960 Stack Capability

Noman,

2960's doesnot support true stacking of the switches like 3750 where you have a common backplane. You can have all the switches connected in a stack and have you SFP uplinks connected in a cross manner like we do in a gigastack cascade configuration. these new switches supports full-duplex operation in between the switch link which wasnot the case in earlier gigastack cascade designs where the uplinks used to work in half-duplex.

These switches can be managed by using switch clustering, please see the link below :

HTH, please rate if it does.

Yes, it will work. No issues you will have inter-vlan working for you in the case listed above with using a l3 switch or router.

Hi Noman,

No, there is not such a cable for 2960's. Its only for 3560's.

Re: Catalyst 2960 Stack Capability

Hi Amit,

Thank you for your response and helping out...

One query though...suppose we connect 2 2960s in a stack (the way u have highlighted above)...and assign the switch ports on both the switches to same VLAN e.g.,VLAN-A..Then in the same manner take another group of 2960s and assign all the ports on these switches to VLAN-B...

Just confirming as a precaution that we should be able to do intervlan routing (via layer3 machine) between these 2 VLANs/stacks...whats your opinion..If u can provide a web-link on this then that will be great...

Re: Catalyst 2960 Stack Capability

Hi Amit,

Thank you for your prompt response...

One more quick query though : ) .... Like in 3560 therez "Cisco Catalyst 3560 SFP Interconnect Cable" available...Is there any such possibility for 2960?

Thanx again for helping out and your prompt responses....

Re: Catalyst 2960 Stack Capability

Hi Amit,

Thank you so much for your great support...

Hope things will work out...

If I m not being too personal, your prompt responses have made me curious : ) about your location in the world...My best guess is u r in US or Australia : ) ...

Re: Catalyst 2960 Stack Capability

Hi Noman,

Things will work, if you face any issues ...dont forget to post here..

BTW,I am located in India.

Re: Catalyst 2960 Stack Capability

Hi Amit,

Just a wild idea...can v use Catalyst 500 in the same context as discussed above...though i couldn't find any relevant info on this...

--Noman Bari

Re: Catalyst 2960 Stack Capability

Hi Noman,

You can do that using CE500 as well.
