HPE FlexNetwork 5510 HI Series Openflow Configuration Guide

Configuring controllers and main connections
An OpenFlow switch supports up to 64 controllers. However, the OpenFlow channel between the
OpenFlow switch and each controller can have only one main connection. The main connection
processes control messages to complete tasks such as deploying entries, obtaining data, and
sending information. The main connection must be a reliable connection using TCP or SSL.
To specify a controller for an OpenFlow switch and configure the main connection to the controller:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter OpenFlow instance
view.
openflow instance
instance-id N/A
3. Specify a controller and
configure the main
connection to the controller.

{

{

By default, an OpenFlow instance
does not have a main connection
to a controller.
Setting the connection interruption mode
An OpenFlow switch is set to either of the following modes when it is disconnected from all
controllers:
• Secure—In this mode, the OpenFlow switch forwards traffic based on flow tables and does not
delete unexpired flow entries.
• Standalone—The OpenFlow switch uses the normal forwarding process.
The OpenFlow switch forwards traffic based on flow tables when it reconnects to a controller
successfully.
To set the connection interruption mode for an OpenFlow switch:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter OpenFlow instance
view.
openflow instance
instance-id N/A
3. Set the connection
interruption mode.
fail-open mode
{
secure
|
standalone
}
By default, the
secure
mode is
used.
Setting OpenFlow timers
An OpenFlow switch supports the following timers:
• Connection detection interval—Interval at which the OpenFlow switch sends an Echo
Request message to a controller. When the OpenFlow switch receives no Echo Reply message
within three connection detection intervals, the OpenFlow switch is disconnected from the
controller.
• Reconnection interval—Interval for the OpenFlow switch to wait before it attempts to
reconnect to a controller.
