OpenFlow is supported in PicOS, and user can configure PicOS switches with both legacy network protocol and Openflow, which will provide extreme flexibility in network deployment.

 

Configure ovsdb-server Locally

Check the ovsdb-server state on the switch. By default, the ovsdb-server listens to the local switch, and the ovs-vswitchd can only be configured by the local switch.

Configure ovsdb-server Remotely

Modify the ovsdb-server state on the switch. Configure the ovsdb-server listening switch management-ethernet interface IP 10.10.51.138 and PORT 6640.
