I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The primary vPC device will not block it's associated ports if the peer link fails. The secondary will block it's vPC member port and the SVI's for any VLANs that are carried by the peer link.

so it is not related to Data plane traffic so that 1 Nexus will be active for data forwarding & the 2nd is as standby
Don JohnstonInstructorCommented:
No. It just determines who forwards in the event of a peer link failure.  And some management tasks.

But nothing to do with forwarding.
