Problem with LACP enabling

[slefebvre]

Hi, 

I have three CBS220-48P-4G-SW1 configured with LAG uplink consisting of two port between each of those switches.

When I try to enable LACP on those LAG I get an error code 387.

Does anybody got this issue and figured how to resolve it ?

          - Check logs on the switches too , when LACP get's enabled
          - Use latest firmware available on the switches
          - Post screenshot of message as it appears ,
