How many switches can be linked via IRF?

Hi there

 

We've bought 5 JE069As. Is it possible to connect all 5 switches via IRF? The indications seem to be that it is limited to 4, which may pose us some problems.

 

Many thanks

 

Simon

Re: How many switches can be linked via IRF?

Depends on the switch type, some types can connect up to 9 others just 2. The 5120 is classed as an edge device rather than core or aggregation so generally these only stack around 4 units. This makes sense really as edge switches tend to only have a couple of links back into the core, usually a couple of 1Gb connections in a link-aggregation. If you are trying to use  this as a core switch, then you may find that this is the wrong product.

5120 = 4

5500 and 58xx = 9

7500, 9500 and 12500 = 2

10500 will be the first core chassie with support for 4 switches in an IRF.

Hi srg

 

Sorry, you've right. I've checked it.

 

On an older roadmap is was announced for automne 2010. But on the current roadmap, it's planned for End of this Year.
