I tried without the ofp_match, only with command=.... However, i got the
same result.
>From another email of this mailing list:
" ... clear1 = of.ofp_flow_mod(match=of.ofp_match(),command=of.OFPFC_DELETE)
clear2 = of.ofp_flow_mod(match=of.ofp_match(),command=of.OFPFC_DELETE)
clear1.match.tp_src =80
clear1.match.tp_dst = 25521
clear2.match.tp_src = 1234
clear2.match.tp_src = 8765
for switch in core.openflow._connections.values():
switch.send(clear1)
switch.send(clear2)
In this case all flow entries are deleted disregarding my match fields(
even delete ARP flow entry..)..."
In my case, ARP msgs are received only after the flow's hard_timeout was
reached, not after the flows were removed by ofpfc_delete. This implies
that the flows are not being properly removed, am I correct?
