Flow control preventing LACP etherchannel 6880X to 3850

[roger perkin]

I am trying to setup a L2 etherchannel between 6880X and a 3850 stack using 10G SFP's 

I am getting this error 

CANNOT_BUNDLE2: Te2/2/13 is not compatible with Te1/2/13 and will be suspended (flow control receive of Te2/2/13 is unknown, Te1/2/13 is on)

What is the optimum setting for flow control in this situation? 

I have read that switch to switch flow control has limited benefits?

The best use is on access ports to end hosts where the host output buffer is potentially as large as the virtual memory

Thanks

Usually below output for flow control is default.

input flow-control is on, output flow-control is off

What is the output of "sh int te1/2/13" and 2/2/13?

Hi,

I have the same issue. But I'm trying to configure etherchannel between C6500 and Nexus

Te2/1/20 is not compatible with Te1/1/20 and will be suspended (Operational flow control receive of Te2/1/20 is on, Te1/1/20 is disagree)

TenGigabitEthernet1/1/20 is up, line protocol is up (connected)
  Full-duplex, 10Gb/s, media type is 10Gbase-CU3M
  input flow-control is off, output flow-control is off

TenGigabitEthernet2/1/20 is up, line protocol is up (connected)
  Full-duplex, 10Gb/s, media type is 10Gbase-CU3M
  input flow-control is on, output flow-control is off

And I can't switch input flow-control on, on the Te1/1/20 or switch off on the Te2/1/20.
