vPC Nexus error LACP with Switch Access

[VuongNguyen2903]

Hi everyone,

You may give the solution for checking and fixing?

I configured vPC member port on 2 Nexus connect Cisco WS-C3850-48P:

On Cisco WS-C3850-48P:

interface GigabitEthernet2/0/17
switchport mode trunk
channel-protocol lacp
channel-group 103 mode active

!
interface Port-channel103
switchport mode trunk

On Nexus:

interface Ethernet1/36
switchport mode trunk
channel-group 40 mode active

interface port-channel40
switchport mode trunk
vpc 103

and show log:

%EC-5-L3DONTBNDL2: Gi1/1/17 suspended: LACP currently not enabled on the remote port

 - You may need to set Port-channel103 on the C3850 in channel mode too , check output of sh etherchan summary (for instance) ,  find out if the 'global portchannel' is seen in the output  ,
