I also see this on my T420 and T320 - the server is powered off but there is still some traffic on all NICs.
As the iDRAC is monitoring the health of the system, this must be one of the ways to check if the link is still up, so it constantly sends packages to see the state of the ports.
So, yes, it is a normal behavior
It might be, that there are some options in the NIC that can reduce this sort of traffic maybe some EEE settings, but I do not recommend changing anything on this.
