OpenFlow Interfaces

This section describes how you can apply OpenFlow to specific interfaces.

• You can use the S4810, S4820T, S6000, S5000, Z9500, MXL or C9000 Series switch as a Hybrid switch, allowing both OpenFlow

(OF) and legacy functionality simultaneously.

• By default, all ports are available for legacy functionality.

• To enable OpenFlow, associate a port or virtual local area network (VLAN) to an OF instance. You can only do this when the OF

instance is disabled.

• OpenFlow is supported with link aggregation groups (LAGs); for example, you can configure port channel interfaces as OF ports or as

members of OF VLANs.

OF Ports

The following configuration example associates two ports (Te 0/7 and Te 0/31) to of-instance 1:

Dell(conf)#interface tengigabitethernet 0/7

Dell(conf-if-te-0/7)#of-instance 1

Dell(conf-if-te-0/7)#interface tengigabitethernet 0/31

Dell(conf-if-te-0/31)#of-instance 1

Dell(conf-if-te-0/31)#

To see the list of ports associated with an OF instance, use the show openflow of-instance command. The number displayed in

parentheses is the port ID sent to the controller (for example, Te 0/7 is sent to the controller as of-port 8, as shown below).

OF VLANs

Instead of assigning an entire port to an OF instance, you can assign a VLAN to an OF instance when you create the VLAN. You can only

create OF VLANs when the associated instance is disabled using the shutdown command. Configure OF VLAN members in the same

way as you would configure a legacy VLAN.
