4 Multi-Service IronWare SDN Configuration Guide

Overview of OpenFlow

The Brocade MLX Series and Brocade NetIron XMR devices support enabling ports in either Layer 2

or Layer 3 mode. The Brocade NetIron CER and Brocade NetIron CES devices support Layer 2 mode

by default (OpenFlow Layer 3 mode configuration on a port is currently not supported on these

devices).

OpenFlow actions

Each OpenFlow flow table entry contains the list of actions to be performed when a packet

matches the flow entry. These actions are defined by the OpenFlow Controller.

Packets that do not match any flow entry are dropped by default. The Brocade implementation

supports an option to send such packets to the controller. Refer to “Configuring the default action”.
