Dear community memebers,
I need to test a scenario containing cisco nexus 9300 switches on a virtual lab. I tried to configure vpc on my switches both in eve and gns3. But I have a problem. I configured my switches, and the vpc is formed fine and is up. It has some port members which they are up too. but the vpc port channel is not working properly. I checked some command outputs which are given bellow.
Can you help me solve the issue to be able to test my scenario, please?
(configurations and the topology are provided too)
I checked this command. You can see the output:
show port-channel load-balance forwarding-path interface port-channel 11 src-ip 1.1.1.1 dst-ip 2.2.2.2
Unknown error.
Error: 0x41a10000
PD Error: -3
(Please check if PO has members and is UP)
But PO has member and is up. look:
sw1(config)# sho vpc brief

Try different latest images of Nexus image.
I work on a day-to-day nexus environment where the command works as expected. Check the correct syntax :

I tried several images and the problem is not solved. the eve and gns3 are both the latest version and I tried nxos 10.3.1F and 10.2.3F which are both new.
As you can see the vpc port-channels are all up without problem, so the config shouldn't be wrong. But it does not work properly. (it works on real switches but it does not on eve or gns)
If you already have a lab on eve or gns with vpc configured, can you check this command and inform me if it works fine:
show port-channel load-balance forwarding-path interface port-channel 11 src-ip 1.1.1.1 dst-ip 2.2.2.2
