Configuring OpenFlow Instances
This section describes how to enable and configure OpenFlow instances on a switch.
• You can use up to 8 OpenFlow instances on a switch. The OpenFlow (OF) ID range is from 1 to 8.
• 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 Z9500 for the Z9500 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
Dell#
• The show openflow of-instance command displays details on the instance, as shown below:

If you do not specify a default VLAN for packet routing, the software assigns the first available VLAN as the default VLAN when you
create the first OF instance. To specify a default VLAN, use the openflow vlan command.
1 Create or modify an OF instance.

2 If this is a new OF instance, continue to step 3. To change an existing OF instance, disable it first.
