Hello,
I found the way to configure the flow limit, however, the flow limit
seems not work. I am still able to insert more than the limitation. Did
I forget something ?

Hello,
I am using Open Vswitch 1.9 and I would like to change the OpenFlow
flow table limit to 1000
However, I see the flow_table is null.
I cannot add an entry using ovs-vsctl (console output below)
Did I forget something?
Thanks

Hi ,
In 1.4.3 this setting for flow limitation is not supported.
*Flow_table* has been introduced by which we can limit flow table
entries size. you can verify from *man ovs-vswitchd.conf.db* in 1.4.3
to see if this Flow_table exists or not.
In *1.7.1 Flow_table * do exists.

Hello,
I am working with OpenFlow and OVSwitch version 1.4.3. I read
somewhere said that OVSwitch's flow table supports up to 10^6
flow entries.
Is it possible to change this limitations (for example, 1000 flow
entries)?
If yes, how to do that ?
Thanks.
Nam
