Re: [ovs-discuss] Flow not registered in OVSDB flow table
Hi Adrian, thank you for your reply. Your suggestion is the same as Ilya's. I used the following command to monitor the OpenFlow commands modifying the flow table: sudo ovs-ofctl monitor switch1 65534 watch: --protocols=OpenFlow13 But the client doesn't receive any packets even I add and delete some entries in the flow table and the changes can be verified with dump-flows command. Only packets like the following are received: OFPT_ECHO_REQUEST (OF1.3) (xid=0x0): 0 bytes of payload Extensions of the protocols with al the versions other than OpenFlow13 doesn't help either. Can you see if the usage of the client with the command above is correct. Regards, Zekeriya >-Ursprüngliche Nachricht- >Von: Adrian Moreno >Gesendet: Freitag, 19.

Re: [ovs-discuss] Flow not registered in OVSDB flow table
Hi Ilya, many thanks for your reply. I'm just wondering what is the table "Flow_Table" of the database is intended for. I have just tried the ovs-ofctl monitor command like this: sudo ovs-ofctl monitor s1 watch: --protocols=OpenFlow13 but the on the flow table through the controller are not printed, even the changes are to be observed via the command sudo ovs-ofctl dump-flows s1 --protocols=Openflow13 Unfortunately I'm not familiar with these commands. Do I use the monitor command correctly? I expect that the flow add and delete request that obviously reach the switch are printed by the monitor. Thank you for any help on that.

OpenFlow rules are not stored in the database, so you can't do that. What you can do is to use OpenFlow monitor instead. ovs-ofctl has a correcponding command.

[ovs-discuss] Flow not registered in OVSDB flow table
Hi all, I'm using ovs through mininet with OpendayLight. The ovs version is 2.13.8 and the mininet version is 2.3.0.dev6. I create a network with a single switch and two hosts. After that I create a flow through the nortboubd interface of opendaylight that works fine. I can also verify with ovs-ofctl that the flow is accepted by the switch. I expected that the flow is also registered in a table in ovsdb, but when I dump the database the flow doesn't appear anywhere in the datastore. Shouldn't the flow be registered in one of the table Flow_Table, sFlow or NetFlow? I aimed to use the ovsdb-client to monitor for changes of the flow table configurations. As I understood ovsdb-client's monitor command this should be doable when changes of the flow configurations lead to changes in ovsdb. Is this approach realistic?
