a unique mac for a breakout 40 Gb interface

Hi,

we're running the 2250 blade in a Viprion 2400. The blade has four 40Gb ports and we're using a breakout cable to carve the 40Gb into 4x10Gb per physical interface. What we noticed is that each 10Gb port has its own mac address and were wondering how is that being done as we would have expected these 4 interfaces to have the same mac as the original 40Gb interface.

 

Thanks.
