HSRP on a pair of redundant Nx7K devices

[axfalk]

We're running a pair of Nx7K devices (A&B) and configured the active HSRP for all the vlans on the Nx7K A device. During a recent issue, we noticed that the traffic for one of the vlans was traversing the Nx7 B device in addition to Nx7K A, i.e. both switches were routing the traffic by sharing the mac address. Is this by design?

Thanks.

With Nexus series switches,that is the correct behavior.

vPC forwards traffic through both the active HSRP router and the standby HSRP router.
