Hi Ben, Let me rephrase my question. I know, how flow entries are added into a single flow table. But, I have few doubts while installing a flow entry into multiple flow tables. 1) Switch can maintain any number of flow tables. But, the controller will come to know about it only through "OFPMT_TA

Exactly the same way as every other OpenFlow switch. There is nothing Open vSwitch specific here. On Wed, Mar 11, 2015 at 06:54:00AM +0530, tech_kals Kals wrote: > Hi Ben, > > am just asking when OVS uses multiple flow tables without > "OFPMP_TABLE_FEATURES". > How it informs the controller? h

Hi Ben, am just asking when OVS uses multiple flow tables without "OFPMP_TABLE_FEATURES". How it informs the controller? how they have been used ? Just wanted to get it clarified... On Tue, Mar 10, 2015 at 11:07 PM, Ben Pfaff wrote: > Your question makes no sense, because OpenFlow 1.1 and 1.2

Your question makes no sense, because OpenFlow 1.1 and 1.2 had multiple tables (in the sense that you mean) but did not have OFPMP_TABLE_FEATURES. Are you saying that these two versions of OpenFlow were useless? If you are, please explain. If you are not, then please consult their specifications

Hi Ben, Thanks for your support. I was asking about how OVS uses multiple flow table when it is not capable of informing controller about it has support for multiple flow tables through OFPMP_TABLE_FEATURES? Since OVS doesnt support OFPMP_TABLE_FEATURES then obviously controller may not be kn

OpenFlow 1.1 and later support the kind of multiple tables you care about. Only OpenFlow 1.3 added OFPMP_TABLE_FEATURES. You can consult the OpenFlow specifications to learn about how OpenFlow works. On Mon, Mar 09, 2015 at 09:41:08AM +0530, tech_kals Kals wrote: > Hi Ben, > > Thanks for your r

Hi Ben, Thanks for your response. Even though OVS 1.3 or later is supporting multiple flow tables. May I know what is the use of them if controller is not informed about multiple flow tables through OFPMT_TABLE_FEATURES. Or do you use some other mechanism to inform the controller about supporting

Hi Ben, In your previous reply to this thread, you had mentioned that OVS 2.4 only will support multiple flow tables. Now, you mention that it is supported in OVS1.3 onwards. I see, OFPMT_TABLE_FEATURES is not supported in OVS 2.1.0. Do you mean, it is supported in 1.3? If it is supported in 1.3
