instance-name

Add a member to this OpenFlow instance.

vlan vlan-id

Adds the VLAN to the named OpenFlow instance.

Flow location

This command sets the location of flows for an instance or the aggregate. In hardware-only mode,

flows are programmed only in hardware. The flows are located in hardware and software by

default.

Syntax

[no] openflow instance { instance-name | aggregate } flow-location

hardware-only

instance-name

Sets flow location for the named instance.

aggregate

Sets flow location for the aggregate instance.

hardware-only

Sets the location of flows to hardware only.

Default: Software and hardware.

NOTE: An error is returned to the controller if the flow cannot be added in

hardware and the flow-location is set as hardware-only.

Communicating port status to the controller

OpenFlow provides the ability to program flows for ports which are not up yet. The OpenFlow

switch communicates port state notification to the controller as part of OFPT_PORT_STATUS message.

This allows the controller to pre-provision flows in the switch referring ports that may be down. The

post status messages are:

• OFPPS_LIVE – Physical link present

• OFPPS_LINK_DOWN – No physical link present

• OFPPS_BLOCKED – Port is blocked

Example

HP-Stack-3800(openflow)# show vlan 3

Status and Counters - VLAN Information - VLAN 3

VLAN ID : 3
