I was trying a new vpc config on a NX-OS switch running "6.0(2)A6(2)" and found that when the feature flexlink is enabled will prevent the feature vpc from being executed. likewise if the feature vpc is enabled you can't enable flexlink.
Checkout these screenshots
So now what are flexlinks?
It's a means for providing a redundant backup uplink with the limitation that you can't run vpc on the switch. With flexlink you define a pair of links with one member placed active and the 2nd member as backup.If the active member goes down, the 2nd member will become active.
So keep that in mind before you defined redundant members and if you plan on using vpc or flexlinks.
