Deployment Guide

• To establish a connection with the controller, enable the OF instance using the no
shutdown command.
• To modify the OF instance, disable the OF instance first using the shutdown
command.
• You can configure one controller IP and one TCP port for each OF instance.
• The number of supported flows depends on the flow type. The following table provides
the number of supported flows for each flow type:
Flow Type Maximum Number of Available Flows
ACL 256 or 512 (depending on ACL CAM carving)
L2 48,000
LB 24,000
L3 6,000
• To avoid session timeout issues if you change the time or date on the system clock,
you must disable and re-enable all existing OpenFlow instances.
