Channel-port connection between Nexus7K and Cisco switch 3650

[wfqk]

HI Any one can confirm the issue fo r me ? I connected Nexus7K with switch3650 by fiber. I configured it as trunk and channel-port. but "show interface status" shows "suspend--" I am not sure if we should use vPC to connect the two device. After I removed channel-port, the connection began to work. Thank you
