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?
OpenFlow flows are not stored in the OVSDB. Only configuration is stored there.
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?
If you want to monitor the changes in the OpenFlow tables you can use "ovs-ofctl
monitor".
Thanks,
Zekeriya
