Hello VEDPSHAR, and thanks for you reply.

Can you say me if this problem occurs in Nexus 9000 series as well?

""There is an existing caveat when Cisco Fabric Extender (FEX) modules are connected to a Cisco Nexus 7000 Series switch. When the switch is manually upgraded, FEX host interfaces (HIFs) lose the configuration after the reload of the Cisco Nexus 7000 Series switch.""

Thanks in advance.
