[ovs-discuss] Reg:Flow deletion

[Ganji Kumara-B38525]

Hi Ben,
   Steps to reproduce:
1) First I have added flow with flow-mod message(add command) with following information
 * priority:10
 * table-id:2
 * Match Fields:
   Type:ethtype value:0x0800
   Type:dest-ipaddr value:2.2.2.0/24
 * Intructions:
   Type:goto-table  value: 03
   Type:write-meta-data value: 0x02020306

Result:   Flow got added successfully.

2) Now delete the same with flow-mod delete strict message with the following information
   * priority:10
   * table-id:2
   * Match Fields
     Type:ethtype value:0x0800
     Type:dest-ipaddr value:2.2.2.0/24
   * out-port:OFPP_ZONE

Result: getting flow-mod error with unknown error code.

Note:I am not using ovs-ofctl to add and delete the flow. I have used our own CLI for this.
     I have verified in wireshark, flow-mod modify message going fine with all given match fields, 
     priority and table-id. I tried the same with Nox switch then it flow got deleted.


Thanks & Regards
Kumarsg

It sounds like a bug.  Can you give instructions for reproducing the problem?
