[pox-dev] How can POX get packet counts (or beta transferred) from a switch within a timeline.

[William Emmanuel Yu]

Hi Weiyang,

Did you check out ofp_flow_stats_request()?

import pox.openflow.libopenflow_01 as of
fsr = of.ofp_flow_stats_request()
sr = of.ofp_stats_request(body = fsr)
switch.send(sr)

Check out:

Good luck!
