I have a customer that would like a 40Gb port-channel between two 3750-x switch stacks. When I try to activate four 10Gb ports in the channel, they go into error-disable. However, I am able to create a 20Gb port-channel without issue. I have had my configurations verified to Cisco best practice.
Is there a limitation on the amount of throughput that the 3750-x can handle? According to the data sheet the 3750X-48T can handle 101.2mpps, based on two 10Gb uplinks so if my math is correct then a stack of two 3750X-48T should be able to handle 202.4mpps.

Thank you in advance for your help.

Hmm, I wonder whether the stack ring's bandwidth might cause an issue. Will a port-channel of 3 x 10 gig come up?

We did not attempt a 3 x 10Gb channel.
