vPC between nexus 93180 and ASR1002

[Seth Beauchamp]

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
