A server is dual-homed to two FEXs off two Nexus 7Ks. Traffic comes into one 7K and it doesn't have a MAC address table entry for the server's MAC so it unknown unicast floods that traffic. This generates a lot of unwanted traffic. The MAC address is in one 7K as a static MAC entry, this is presumably due to the port security method setup (sticky). Has anyone else seen this behavoir with sticky port-security on a pair of 7Ks setup in vPC mode with each other?
