Hi.


I hope you can support me with the following question:


What does the "Flow Cntrl" column indicate, shown in the "show ports configuration" command?


What does it mean: SYM, SY / ASY, NONE?




Greetings.

Hello Jorge,

"Flowcontrol" capability of peer device could be next:
  • None - peer device cannot send and receive pause frame.
  • symmetric mode - can send and receive pause frame.
  • asymmetric mode - only able to send pause frame.
  • symmetric/asymmetric mode - can Send and/or Receive (both symmetric or asymmetric)

Best Regards,
Nikolay
