The embedded Packet Velocity Acceleration (ePVA) statistics are showing extremely high throughput and pps (much higher than the sum of all external interfaces). A relatively high amount of epva_connstat tot.snoop_dynamic is observed in comparison to other types of offloading.


Some stats in the tmstat tables are incorrect, but these stats are primarily used for diagnostic purposes.


Hardware traffic acceleration is activated.


There is no good workaround for the stats issue.
