• MODIFY FIELD — Modify Ethernet source MAC address: Changes the Ethernet source MAC address to the specified

value.

• MODIFY FIELD — Modify Ethernet destination MAC address: Changes the Ethernet destination MAC address to the

specified value.

• MODIFY FIELD — Modify IPv4 ToS bits: Changes the IPv4 ToS in the packet header to the specified value.

• OFPAT_ENQUEUE: Send the specified flow to the queue.

NOTE: If there is a conflict between actions, the action with the higher priority takes precedence.

Unsupported OpenFlow Messages

The following OpenFlow messages are not supported. Some unsupported messages generate OFPT_ERROR, which is an error message

sent to the controller.

OFPT_QUEUE_GET_CONFIG_REQUEST

OFPT_ERROR generates in response.

OFPT_PORT_MOD

OFPT_ERROR generates in response.

Emergency Flows (OFPFF_EMERG) OFPT_ERROR generates in response.

Queue Statistics (OFPST_QUEUE) OFPT_ERROR generates in response.

For supported flow-match and flow action parameters for each flow type, refer to Flow Types. The following is a list of actions

that are not supported for any flow types. All of the following commands generate an OFPT_ERROR message.

• OFPAT_SET_TP_SRC (set tcp/udp src-port)

• OFPAT_SET_TP_DST (set tcp/udp dst-port)

• OFPAT_OUTPUT to OFPP_IN_PORT

• OFPAT_OUTPUT to OFPP_TABLE

• OFPAT_OUTPUT to OFPP_NORMAL

• OFPAT_OUTPUT to OFPP_LOCAL

• FORWARD — Normal
