IRF3(Intelligent Resilient Framework 3). As google translation is not that great, can someone please explain the difference between IRF2 and IRF3?

Hi Michael

 

IRF 3.0 will be vertical stacking. Stack a Switch with an other Switch-Model. It is like the Ciscos Nexus 7000 stacking with Nexus 2000 Portextenders.

 

Would be a great thing for datacenters.

Re: IRF3(Intelligent Resilient Framework 3) ?

What are the chances that this will include already existing models and not just future models?

 

Im thinking of doing this between a 5120EI and 5820?

So it´s called Vertical IRF with "Controlling Bridge" and "Port Extender" devices.

Btw, interesting there´s an HP S5120-HI mentioned.

Re: IRF3(Intelligent Resilient Framework 3) ?

As mentioned IRF 3 (as well called vertical-irf or VCF) is the evolution of the

horizontally built IRF 2 into the vertical axis.

We talk by now abot avery limited amount of devices that will actually support IRF 3.

 

As controling bridge: 12500 series / 11900 series and the 5900th

AS Port extender: 5500HI familie, 5700 familie and the 5900th.

 

The usage model is either:

 - within the data center: any of the CB + either 5700th or 5900th or combinations as PE

-  within campus envirinments: any of the CBs as building collector + combinations of 5500HI POE and the others as PE

 

The differentiator to the nexus approach is: A PE in an IRF 3 is doing Layer 2! Therefore local switching.

 

The feature is closly bound to the availability of Comware OS 7. So a close look into the availability of Comware 7 in above mentioned devides would make sense.

 

Hope this helps
