Hi, I am having great difficulty in setting the cookie field using ovs-oftl tool. The value seems to be set sometimes and not other times. What is the correct way to set this value in the flow definition for OF 1.0 switch.
#./ovs-ofctl mod-flows switch "cookie=20000,hard_timeout=9999,in_port=8,dl_vlan=4,dl_vlan_pcp=2,dl_type=0x800,nw_proto=6,nw_tos=0,actions=output:2" -v Sep 04 07:32:03|00001|ofctl|INFO|connecting to unix:/var/run/openvswitch/switch.mgmt Sep 04 07:32:03|00002|vconn|DBG|unix:/var/run/openvswitch/switch.mgmt: sent (Success): hello (xid=0x83bc0): Sep 04 07:32:03|00003|vconn|DBG|unix:/var/run/openvswitch/switch.mgmt: received: hello (xid=0x1db0d): Sep 04 07:32:03|00004|vconn|DBG|unix:/var/run/openvswitch/switch.mgmt: negotiated OpenFlow version 0x01 (we support versions 0x01 to 0x01 inclusive, peer no later than version 0x01) Sep 04 07:32:03|00005|vconn|DBG|unix:/var/run/openvswitch/switch.mgmt: sent (Success): flow_mod (xid=0x43c26):tcp,in_port=8,dl_vlan=4,dl_vlan_pcp=2, MOD: cookie:0x4e20 idle:60 hard:9999 pri:32768 buf:0xffffffff flags:0 actions=output:2 # ./ovs-ofctl dump-flows switch Sep 04 07:32:11|00001|ofctl|INFO|connecting to unix:/var/run/openvswitch/switch.mgmt stats_reply (xid=0x41bd): flags=none type=1(flow) cookie=0x0, duration_sec=8s, duration_nsec=152000000ns, table_id=0, priority=32768, n_packets=0, n_bytes=0, idle_timeout=60,hard_timeout=9999,tcp,in_port=8,dl_vlan=4,dl_vlan_pcp=2,actions=output:2 dl_vlan=4,dl_vlan_pcp=2,dl_type=0x800,nw_proto=6,nw_tos=0,actions=output:2" -v8,d See the cookie value is not set.

Thanks for your help. -- With best regards, Bhaskar.
