• Multiple Flow tables

◦ Pipeline processing

• OpenFlow physical, logical and reserve ports

• Version negotiation

• Group tables

• Auxiliary connections

• OpenFlow Extensible Match (OXM)

• Multiple controllers

• Support for IPv6 flows

OpenFlow switch side configuration enables the user to:

• Enable or disable OpenFlow

• Create OpenFlow instances and configure controller connections

• Display OpenFlow related configuration

• Availability of Config support to retain OpenFlow configuration across a reboot

OpenFlow supports high availability:

• The OpenFlow flow table is preserved across Management Module failover

• The OpenFlow configuration is synced from the AMM to the SMM

OpenFlow includes tools for limiting resources:

• Support for limiting the percentage of policy engine and IP control table resources used by

OpenFlow

• Support for rate-limiting the amount of OpenFlow traffic sent to the controller

• Support for rate-limiting the amount of OpenFlow traffic that gets forwarded by the policy

engine rules programmed by OpenFlow

OpenFlow modes of operation:

• Support for hardware-only mode such where only flows that can be programmed into hardware

are accepted from the controller.

• Support for active mode (default) where new flows are sent to the controller by the switch.

• Support for passive mode where new flows no longer are sent to the controller but are handled

normally handled by the switch.

IPv6 and OpenFlow

Directing IPv6 traffic using OpenFlow is supported beginning with OpenFlow Specification 1.3.

For more information on configuring IPv6 on switches, see the IPv6 Configuration Guide for your

switch.

Administrative methods

This document provides the HP CLI commands for configuring and administering HP OpenFlow

switches.

OpenFlow controllers include utilities for monitoring, administering, and troubleshooting OpenFlow

switches. For example, the OpenvSwitch controller distribution includes the utility ovs-ofctl.

The utility can show the current state of a switch that supports OpenFlow, including features,

configuration and table entries. Other controllers have similar utilities; see the documentation for

your controller for the complete command set.
