Which port of Nexus7 is connected to device B

Hi, devices B is connected to Nexus7K. After we logon to Nexus7K, based on the output of show ip arp and show mac address-table, we can know Device B is connected to Nexus7K via vlan 100, but vlan 100 have several ports on Nexus7K. How can we know which port in Nexus7K is connected to Device B. Thank you

When you look at the mac address table - it will show you what port the mac address lives on.  So the mac-address table will show exactly what port your device is on.
