I am trying to create this scenario:
Unfortunately, I don't have remote-access to collect configurations, but general it goes:
VPC domain 1 configured on 7K
VPC domain 10 configured on 5K
On 5K-A interf 1/1 goes to 1/1 7K-A, 1/2 goes to 1/2 7K-B.
On 5K-B interf 1/1 goes to 2/1 7K-A, 1/2 goes to 2/2 7K-B
All interfaces are configured as trunks, port-channel 10 mode active
On port-channel 10 there is command VPC 10.
Now the here is the issue:
When I connect all interfaces, all my ethernet interfaces go to suspended state. If I shut-down 5K-B, and have on 5K-A dual homed, still not working.
When I remove VPC from PO interfaceon N5K-A, it start's working, VPC on N7Ks is up and running, while it is just regular Po on N5K-A.
On the other hand when I shut down N7K-B, and remove VPC configuration from Po port on N7K-A and practicaly make it regular Po that will go to two N5Ks, again it start working. On N5K VPC is up and running and on 7K-A I have regular Po interface...
I am pretty sure that I was able to make VPC-to-VPC connection between pair of 7K and pair of 5K, but now it doesn't seem to be working...
Is there anyone with working configuration to share? Also, is there any know issue I should be aware of?
Thanks.
