Show ip arp in Nexus7000

[wfqk]

Hi Any expert can give some suggestion? The Nexus7000 is connected with several devices. but when show ip arp, nothing appears. Thank you

Can you tell us about the configuration of the Nexus? Is it using VDC? If so which VDC are you in? How many routed interfaces does it have? Can you post the output of show ip interface brief?

Thank you for your reply. 

We only have one default VDC. The below is part output of show ip interface brief:

N7k# show ip interface bri

Thank you for the additional output. It shows just one physical interface which is down, and two virtual interfaces one of which is down. If there is only one interface which is up then I can explain your problem. The one interface which is up sends an arp request but there is no interface which can send an arp response. So there are no entries in the arp table.
