Data Center Technology Commands 1195
User Guidelines
This command configures the switch to accept a connection request from a
controller. When passive mode is enabled, the switch accepts TCP
connections to ports 6632 and 6633 respectively using any switch IP address.
In this mode, the switch continues to attempt to initiate connections to
configured controllers.
The OpenFlow component always initiates the SSL connections and does not
accept SSL connections.
OpenFlow operates on the stack master 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 configures a connection to the controller at IPv4 address 1.2.3.4
TCP port 3435 using SSL security and also configures the controller to accept
TCP connections to the switch on port 6633.
console(config)#openflow
WARNING! OpenFlow does not operate on stack members. Enable OpenFlow on
stand-alone switches only.

which to operate. Use the no form of the command to return the
