I have a vPC between a 93180 and an ASR1002 that im not sure is configured correctly. From the nexus switches I see that the port-channel members are in the I (individual) state and show lacp counter shows no received PDUs. It seems to be functional, but shouldn't i see lacp PDUs? Does "spanning-tree bpduguard enable" block lacp PDUs as well?
My nexus port channel configurations:
interface port-channel4
switchport
switchport mode trunk
spanning-tree port type edge trunk
spanning-tree bpduguard enable
no lacp suspend-individual
vpc 4
interface Ethernet1/3
switchport
switchport mode trunk
channel-group 4 mode active
no shutdown
My ASR1002 port channel configuration:
interface Port-channel4
no ip address
end
interface TenGigabitEthernet0/1/2
no ip address
cdp enable
channel-group 4
Not shown here, but I have a sub interface on the port channel on the AS1002 side with an IP on it. I can ping across and BGP comes up with another device.

we need to have both the side config to look along with show etherchannel summary, show port-chann summary from nexus
or try
channel-group 4 mode on - both the sides.

Hello
have you enabled lacp in the Nxos?
Also on the asr I can see no dot1q or switchport interfaces so the PC won’t establish as a trunk
