Hi everyone,
Need some help here...
I am configuring vPC between two Nexus 9K, C93240YC-FX2. Port-channel 10 is the vPC peer link and is up. However, "show vpc" shows peer link is down. I have tried to re-configure vpc, port-channel, shut/un-shut vpc, shut/un-shut port-channel, reboot both N9Ks, but nothing worked to bring up vPC.
Appreciate any suggestions.
Thanks,
Fei.
Below are show output from both N9Ks.
