Anyone can explain "vrf context management" in Nexus7k to me ?

Hi Expert, I met the following commands in Nexus7k. I am not very sure the following commands. I would like you explain it to me. Do you think there is difference between following vrf and vrf in MPLS ? What is the meaning of "vrf context management" Thank you.

Instead of just a console port for out of band management like you find on many Cisco routers and switches, the Nexus switches have a Management Ethernet interface.  This is basically a console port that is not a 9,600bps serial port but is a 1gbps ethernet port.  

While It is ethernet, it is also entirely out of band.  Meaning the traffic in/out of this port never intermingles with the data traffic.  But because it is ethernet, we need a way to segregate it internally.  So a VRF context exists just for the traffic on the management ethernet port.

The only thing to add is that the other networking lines you listed are meant entirely for the management context to route traffic back to whomever is making a connection to the management interface.

Do you think there is difference of the vrf between in MPLS and in the Nexus 7000 ?

Not sure what you mean.  MPLS is a protocol/service.  Nexus is a line of switches.
