OpenFlow v1.3.0 instructions

Each flow entry has a set of instructions that are executed when the packet matches the entry.

The instruction set associated with each flow entry can have a maximum of one instruction of each type. The following table shows the actions supported on different RUCKUS ICX devices.

Goto -Table next-table-id ( Req ) Indicates the next table in pipeline processing. No
Write-Metadata metadata/mask Writes the metadata field from the mask. No
Output (Req) Forwards the packet to a specified OpenFlow port. If out-port is Controller, then the packet is sent as packet-in message. Yes
Drop (Req) No explicit drop action. Packet with empty action set is dropped. Yes
Group Processes the packet through the specified group. Yes
Set field Modifies the values of the packet header based on the field type. Yes
Push-Tag/ Pop-Tag Adds and removes tag (newly inserted tags are always the outermost tags). Yes
Set-Queue Enqueues the packet to a specific queue on the outgoing port. Yes
Decrement TTL Decrements the TTL value by 1. Yes1
