Ether-Channel on 3750G-16TD-S & 3750x-48T-S with 10GB

Anyone have any experience with bundling a 10GB interface on a 3750G-16TD-S with a WS-C3750X-48T-S with a 10GB interface. I have worked with 5 different TAC engineers and so far I have not gotten an answer on why the switch will not let me bundle the 10GB with another 10GB interface.

Same switch Stack – not a cross stack.

Tried every configuration possible with no luck.   I originally thought it might be the stack-ring speed – I corrected that today and it is running at 32GB –

The only thing I can think of now is it might be a hardware limitation on the 3750G-16TD-S ?

Q. What performance of the 10 Gigabit Ethernet port on the Cisco Catalyst WS-C3750G-16TD switches?

A. The Ten Gigabit Ethernet uplink on the Cisco Catalyst WS-C3750G-16TD switches is 1.25:1 oversubscribed and provides maximum throughput of 8Gb/s.   –

Any advice or thoughts are greatly appreciated.

What version of IOS are you running and what type license level do you have for each device?

IOS level is 12.2.55.SE3 - IP Base license level.  I am leaning towards the stackwise limitation of the 3750G - Any thoughts?

Hi Rudy,

Did you get to the bottom of your problem? We're attempting a similar ether bundle: our stack is made up of various 3750s, and we're trying to bundle a 3750G-16T 10G port with a 3750X 10G port.. we've tried proven configurations, but can't get the bundle operational when we include the 3750G-16T.

Our error is as follows:

#channel-group xx mode passive

Command rejected (Port-channelxx, Tex/y/z): Cannot configure interface for bundling

Any information would be greatly appreciated.
