Hi Guanyao, I have tested dpctl on switch openflow and it show me the stats about aggregating flows perfectly.
I used the secchan, dpctl e openflow_mod.ko available in NOX Virtual Test Environment setup. But the monitor component continue showing all values with zero :( On Tue, Feb 2, 2010 at 11:32 PM, Guanyao Huang <[email protected]> wrote: > I guess it depends on whether dpctl dump-aggregate works correctly. > My problem with it is that sometimes it can not aggregate flows > according to the specified wildcard.
