OpenFlow Interfaces

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

• You can use the S4810, S4820T, S6000, Z9000 or MXL 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
