Connectivity Guide

• negotiate—Enter the keyword to negotiate versions 1.0 or 1.3 with the controller. The highest of the
supported versions is selected.
• 1.0—Specify the logical switch instance OpenFlow protocol version as 1.0.
• 1.3—Specify the logical switch instance OpenFlow protocol version as 1.3.
Default
negotiate
Command Mode OPENFLOW SWITCH CONFIGURATION
Usage Information
NOTE: Only use this command should be run when the logical switch instance is disabled. Use the
shutdown command to disable the logical switch instance. After you run this command, enter the no
shutdown command to enable the logical switch instance again.
• When you specify, negotiate, the switch negotiates versions 1.0 and 1.3 and selects the highest of the
versions supported by the controller. The negotiation is based on the hello handshake described in the
OpenFlow Specication 1.3.
• When you specify, 1.0, the switch establishes a connection with the controller that supports version 1.0 only.
• When you specify, 1.3, the switch establishes a connection with the controller that supports version 1.3 only.
Example
The following example shows a logical switch instance, of-switch-1, congured to interact with controllers that
support the OpenFlow protocol version 1.3.
OS10 (config)# openflow
OS10 (config-openflow)# switch of-switch-1
OS10 (config-openflow-switch)# shutdown
OS10 (config-openflow-switch)# protocol-version 1.3
OS10 (config-openflow-switch)# no shutdown
OS10 (config-openflow-switch)#
Supported Releases 10.4.1 or later
rate-limit packet_in
Congures the maximum packet rate for the controller connection, and the maximum packets permitted in a burst sent to the controller in
a second.
Syntax
rate-limit packet_in controller-packet-rate [burst maximum-packets-to-
controller]
Parameters
• controller-packet-rate—Rate in packets per second for the controller OpenFlow channel connection,
from 100 to 268000000 seconds. The default is 0 seconds, disabled.
• maximum-packets-to-controller—Burst in packets for the controller OpenFlow channel connection,
from 25 to 1073000. The default is 0 seconds, disabled. This parameter is optional. It is set to 25% of the
congured rate value, if not congured.
Default Disabled
Command Mode OPENFLOW SWITCH CONFIGURATION
Usage Information
OpenFlow sets the specied rate and burst for the controller's connection with the logical switch instance. The
actual rate and burst on the controller has a maximum of two times the congured values. For example, when you
congure a rate of 1000 PPS and a burst of 300 packet bursts per second, the packets can egress on the
connection at rates of up to 2000 PPS and 600 packet bursts per second.
