Supported Flow Actions

The following flow actions are supported:

• OFPAT_FLOOD or OFPAT_ALL: Floods packets to all ports and VLANs on the OF interface.

• OFPAT_CONTROLLER: Sends all NO_MATCH or ACTION packets to the controller specified by the packet’s VLAN tag.

• OFPAT_out_port: Displays a list of ports that can receive traffic.

• OFPAT_DROP: Drops all packets that match the specified criteria.

• OFPXMT12_OFB_ETH_TYPE — Ethernet frame type

• OFPXMT12_OFB_VLAN_PCP — VLAN priority

• MODIFY FIELD — Set VLAN ID: Assigns a VLAN ID (0 to 4094).

• MODIFY FIELD - Strip Vlan ID: Strips VLAN ID from the packet.

• MODIFY FIELD — Set VLAN priority: Assigns a priority to a VLAN (0 to 7).

• 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.

Table 4. Unsupported OpenFlow Messages

Message System Response

OFPT_SET_CONFIG

This message is ignored by the switch.

OFPT_QUEUE_GET_CONFIG_REQUEST

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_NW_SRC (set src-ip)

• OFPAT_SET_NW_DST (set dst-ip)

• OFPAT_SET_TP_SRC (set tcp/udp src-port)

• OFPAT_SET_TP_DST (set tcp/udp dst-port)
