More than 8 LAGs

Hi,

I'm curios: what would be the way to go if you needed more than eight LAGs? As I understand, eight is the maximum for both the SG300 and SG500 series.

Thanks!

The 2960-X should support up

The 2960-X should support up to 24 etherchannels:

You will need to create a whole new IEEE Standard.

Thank you for pointing this

Thank you for pointing this out. I wasn't aware that this limit is actually imposed by the standard. Is there any other way to achieve link redundancy for more than eight devices (e.g. connecting 9 servers with two cables each)?

Uh-oh.  Houston?  I think we got a problem.  

 

I think I misunderstood your intention.  I initially thought you want nine and more physical links to form an etherchannel.   Each LAG/Ethernchannel has a maximum of eight physical links.  You're not talking about the physical links.  You're talking about the maximum amount of LAGs/Etherchannels.

 

Yes, this is very much possible.  The only limitation on how many LAGs/Etherchannels you can have will depend entirely upon the model of your switch.

 

My sincerest apologies for the confusion.  I have erred.
