Hello,
I looked now some time around, but unfortunately I wasn't able to figure out what limitations regarding etherchannels I have with a Cisco switch stack.
For one of our projects I plan to build the platform based on microblades. In sum I plan to stack 4 switches (48 ports) for the internal switching layer and will need to configure around 70 etherchannel groups. I found the following values on the Cisco homepage, but I am not sure if those values apply per switch or stack
WS-C2960X-48TD-L LAN Base 24 Etherchannel groups
WS-C2960XR-48TD-I IP Lite 48 Etherchannel groups
Does somebody know how many Etherchannel groups I can configure per stack. Most of micro blade will have 2 or 4 network cables which I want to split over the switches for redundancy purposes.
I am also open to discuss, if somebody has a better idea.
Thanks for your support

For the 2960X
From the config guide
Do not try to configure more than 24 EtherChannels on the switch or switch stack.
So it is 24 per stack
For the 2960XR
Do not try to configure more than 24 EtherChannels on the switch or switch stack.
So it is 24 per stack

Hi Alex,
thanks for the links. According to below link the 2960XR can handle 48 etherchannels which is still not enough for the solution I plan (table 2):
I want to keep this solution as simple as possible and therefore I don't want to use different stacks. Any other idea how to build it up with Cisco?
3750x seems to have a limitation of 48 etherchannels.
Otherwise it seems that I have to use Dell, according to their documentation they support 128 groups per stack.
Thx,
Daniel

Daniel,
On the smaller type switches even moving up to the top of the range 4500X you are linited to 64 etherchannels
A 6500 can be up to 128 channels but I dont think the costs of you project would warrant this if you are looking at the smaller size switches

Seems that I have to look for something else or split it up into different stacks.
Thanks for the support Alex!
Cheers,
Daniel
