Crossflow Basic Configuration

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 ovs-vswitchd Locally

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.
