Description (partial)

On a Nexus 7000 running 6.2(2) code broadcast frames coming from the peer-link might not be forwarded to host ports on a Nexus 2000 fabric extender.  This leads to incomplete ARP entries on the Nexus where the fabric extender is not connected.

You must be using module type N7K-F248XP-25 or N7K-F248XP-25E and the card had to reload (or the chassis).  If you did an non-disruptive ISSU you will not see this issue until the card reloads.
