Data Center Technology Commands 1235
User Guidelines
If connection to the controller over an interface other than the OOB interface
is desired, use the OpenFlow mode command prior to issuing this command.
Issuing the mode command after a connection has been established drops the
connection. The connections are then re-attempted over the new interface as
specified by the mode command.
If the OOB interface is used to connect to the OpenFlow controllers, the
controllers should be on the same subnet as the OOB interface.
When using the no form of the command, if no port number is given, all
controller entries for the IP address are deleted.
If SSL is used, an SSL certificate should be downloaded using the copy
command prior to configuring the controller.
OpenFlow operates on the management unit in the stack only. Flows may not
be configured on stack members. Failover to the stack standby unit is not
supported. OpenFlow should only be enabled on stand-alone switches and
should not be enabled on stacks of switches. This restriction is not enforced.
Command History
Introduced in version 6.3.0.1 firmware.
Example
This example enables OpenFlow 1.3 on a switch and configures a connection
the controller at IPv4 address 1.2.3.4 TCP port 3435 using SSL security. A
signed CA certificate, switch certificate, and switch private key should be
downloaded to the switch using the copy command.
console(config)#openflow
WARNING! OpenFlow does not operate on stack members. Enable OpenFlow on
stand-alone switches only.
