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).
FTOS#show openflow of-instance 1
Instance : 1
Admin State : Up
Interface Type : Port
DP Id : 00:01:00:01:e8:8b:1a:30
Forwarding Tbls : acl
Flow map :
LB assist : disabled
EchoReq interval : 15 seconds
Connect interval : 15 seconds
Number of Flows : 1 (acl:1)
Packets (acl) : 0
Bytes (acl) : 0
Controller 1 : TCP, 10.11.205.184/6633, connected (equal)
Controller 2 : -

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.
