Hello,

using two NEXUS 56128 , I wish to create enhanced VPC architecture with FEX 2248TP.

My question is : can I use 40Gbs ports on NX56128 with QSFP breakout DAC cable (40G to 4x10G) to connect FEX 2248 ?

regards

Hi,

 

since it is possible to connect a FEX (2248PQ) with one native 4GE Port via breakout cable to N56128. 

Is there any additional configuration required or does the 40GE breakout cable force the port to 4x10GE?

 

thanks 

Udo

On my 6001's I had to run interface breakout, then they went from 2/1 to 2/1/1-4

 

interface breakout slot 2 port 1-2 map 10g-4x
