Hi,  I found a problem let if there actually have 18 or more flows in Zodiac FX.

And if send OFPFlowStatsRequest(no give any filter parameters) to Zodiac FX.

It replied flows stats count seem like limit <= 18

Is that hardware limit?

firmware version v0.65

Hi,

I'll have a look and let you know, it may be a flow stats buffer issue.
