[c-nsp] Getting Source MAC of "sh buffers" output

["Rolf Hanßen"]

Hello,

I think we got a flooding with ARP packets towards a SUP720-3B, I saw that
here with "sh buffers input-interface vlan xy header":

Is there a way to find out the MAC-address those packets are coming from ?
None of the numbers looks like a MAC to me.

kind regards
