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.
