Hi All,
I have a scenario where I have two nexus 5596 as upstream and have vPC in between. downstream is the server hooking to the upstrean both nexus devices.
On Both the Nexus switch the port channel is down and the VPC is also down. The physical interfaces are up and passing traffic to the server.
My understanding is if the server NIC's are teamed, even the switches should also have the portchannle to work properly.
But since portchannel and vpc both are down in both the switches
1. how the switch is passing traffic.
2. I checked the configs for portchannel formation on phy ports which looks good to me still po is down. Why?
3. I understand as port channel is down so vPC is down ( correct me if I am wrong).
I have attached the diagram & below are the logs for ur reference:
The output on Nexus5596 2 device is same as on Nexus5596 1
