Dell EMC SmartFabric OS10 User Guide Release 10.5.0

• 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 configured rate value, if not configured.

OpenFlow sets the specified 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 configured values. For example, when you configure 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.

The no form of this command disables rate limiting on the controller connection.

The following example configures a logical switch instance, of-switch-1, with an OpenFlow controller at a rate of 1000 PPS and packet bursts of 300 packets.

OS10 (config)# openflow
OS10 (config-openflow)# switch of-switch-1
OS10 (config-openflow-switch)# controller ipv4 10.11.63.56 port 6633
OS10 (config-openflow-switch)# rate-limit packet_in 1000 burst 300
OS10 (config-openflow-switch)#
