That's a legacy from the sup 1's.  CMP ports have been discontinued on subsequent supervisor engines.

Basically the CMP ports were a backdoors into the management. They allowed "lights off" management of the switch. You could literally shut down the switch and bring it back up through the CMP port.

On the sup was a completely segregated Linux based PC with its own CPU, RAM, ROM and NIC ( the CMP port).  But were almost never used so Cisco discontinued them.

Thank you so much for your fast reply. I am not sure the function of " ip default-gateway 172.16.10.1". Do you think " ip default-gateway 172.16.10.1" is necessary since the Nexus7k is layer 3 switch and it has a lot SVI interface ?

That is the default gateway for the CMP.  Notice how that command is indented under the "interface cmp-mgmt" command? That means it's relevant to the CMP only.

Once again, think of the CMP as a standalone computer.  As such, it requires an IP address, mask and default-gateway.
