Description (partial)

Link between Nexus 7000 and ASA 5585 malfunction

after upgrading N7K, we found the function between N7K and ASA not working.

All vpc links, interfaces and vlans on N7K were up and look fine on both side of N7K and ASA, and from N7K we could ping to ASA directly connected interfaces, but ping to the NAT address failed.
For example, we have vlan 110 with IP 192.6.11.x.  On N7k, we can ping ASA vlan 110 IP address, however, data packet in VLAN can not go through ASA NAT.

In data center CUCM can trace route to endpoint Cisco Ip phone which go through N7K and ASA. However, CUCM can't ping endpoint Cisco Ip phone, data is stopped at N7K. And endpoint Cisco Ip phone can't CUCM in data center.
