OpenFlow Interfaces

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

•

You can use the S4810 and Z9000 as Hybrid switches, allowing both OpenFlow (OF) and legacy functionality

simultaneously.

•

By default, all ports are available for legacy functionality.

•

To enable OpenFlow, associate a port or VLAN to an OF instance. You can only do this when the OF instance is

disabled (in a "shut" state).

•

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:

FTOS(conf)#interface tengigabitethernet 0/7

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

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

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

FTOS(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. You must do this when

the VLAN is created. You must enter OF VLAN members in the same way as a legacy VLAN.
