Hello everyone, I have an OvS bridge *X *and some network interfaces connected to it via OpenFlow ports. For each interface connected to *X*, I want to display the name and the number of its OpenFlow port. I've been using the following command: "ovs-vsctl -f table -- --columns=ofport,name list Inte

[ovs-discuss] OVN: resync nb-db to sb-db

2020-07-28 Thread Tony Liu
Hi, When I run a script to create bunch of networks and routers from OpenStack, for whatever reason, nb-db is fully updated, but sb-db is only partially updated. For example, there are 500 logical routers in nb-db, but only 218 datapath bindings in sb-db. In this case, is there any way to resyn

[ovs-discuss] max_speed and curr_speed is incorrect

Hi, I want to collect ports’ curr_speed and max_speed from ovs to calculate ports’ bandwidth on Mininet. However, no matter how I set the bandwidth, the value of max_speed is always 0 and value of curr_speed is always 1000. I’m using ovs 2.13.0 in Mininet 2.3.0b6. Could anyone tell me how

[ovs-discuss] OVN: configuration in Neutron DB?

2020-07-28 Thread Tony Liu
Hi, In case of integration with OpenStack, for example, when a client requests to create a network, is this network configuration saved in both Neutron DB and OVN DB, or OVN DB only? Also, when a client gets a network from Neutron API, is the configuration read from Neutron DB or OVN DB? Other

Quick update. I changed the script to create 256 routers first, then set each of them as gateway. There is no create and set back to back. It seems working fine now. It would be good someone can clarify my questions. It seems that it's not guaranteed that the object is ready when client get OK r
