RE: [802.3ae] 10 Gig XGMII

Title: 10 Gig XGMII
If the implementation is to the current spec, the TX side can logically be connected to the RX side and data should be looped back.  If your purpose is to validate the XGMII implementation, it won't do a very good job (no testing of the link fault state machine, error handling, etc.) 
 
The connection is straight forward:  TXD<0> to RXD<0> ..., TXC<0> to RXC<0>..., and  TXCLK to RXCLK. 
 
Obviously, you will need to assure that when you loop the signals back that setup and hold times are met.

Hi,

I am working with a 10 Gig Net Processor that got an XGMII interface.
I would like to know if I can connect the RX port to the TX port  in the XGMII interface ( to perform a loop).
In case the answer is yes, can u advise me about the proper way to do it?
Regards.
