Configuring OpenFlow Instances

This section describes how to enable and configure OpenFlow instances on a switch.

• You can use up to 16 OpenFlow instances on a switch. The OpenFlow (OF) ID range is from 1 to 16.

• You must allocate CAM blocks for use by OpenFlow before configuring any OpenFlow instances. For

more information, refer to Configuring ACL CAM Carving on the S4810, S4820T, S6000, and MXL

switch for S4810, S4820T, S6000, and MXL switches or Configuring ACL CAM Carving on Z9000 for

the Z9000 platform.

• Only transmission control protocol (TCP) connections are supported on Dell Networking switches.

Transport layer security (TLS) connections are not supported.

• You can configure only one controller IP and one TCP port for each OF instance.

• The connection is established when you enable the OF instance using the no shut command.

• You cannot modify the OF instance while it is enabled. To make configuration changes, use the

shutdown command to disable the OF instance, as shown below.

Dell#show running-config openflow of-instance

openflow of-instance 1

controller 1 10.11.205.184 tcp

shutdown

• The show openflow of-instance command displays details on the instance, as shown below:
