Output Fields for the Show Openflow Command

Field

Description

Administrative Status

Indicates the administrative status of OpenFlow on the device.

SSL Status

Indicates the SSL status of OpenFlow on the device.

Controller Type

Indicates the OpenFlow protocol version that is supported on the device.

Number of Controllers

Lists the number of controller connections configured on the device. Up to three concurrent controller connections are supported.

Connection Mode

Indicates the mode of the controller connection configured. You can configure active or passive connection to controllers. An active connection is initiated by the device. In a passive connection, the device is in the listening mode, and accepts requests from controllers. If the optional controller address is not specified, any controller can establish a connection with the device in the passive mode. Refer to Connecting to an OpenFlow Controller.

Listening Address

Indicates the address of the specified controller.

Connection Port

Indicates the TCP port that is used for connection to the controller. By default, port 6633 is used.

Connection Status

Indicates the controller connection port status.

Match Capability

Specifies the matching rules supported.

Normal OpenFlow Enabled Ports

Lists the ports on the device that are enabled for OpenFlow.

OpenFlow Hybrid Interfaces

Indicates the VLAN IDs.

Default action

Indicates the default action for packets that do not match any configured flows. By default, such packets are dropped. However, you can configure these packets to be sent to the controller by using the openflow default send-to-controller command.

Maximum number of flows allowed

Indicates the maximum number of flows allowed on the device that is configured by using the system-max openflow-flow-entries command.
