Configuring OpenFlow Instances

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

• You can use up to eight 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 Config_ACL_CAM_Carving for S4810, S4820T, and MXL switches or

Config_ACL_CAM_Carving_Z9k 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 shut command

on the OF instance, as shown below.

FTOS#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:

2. Disable the OF instance.

NOTE: All new OpenFlow instances are disabled by default. For existing OpenFlow instances, you must disable

the OpenFlow instance before you can configure it.
