Software and hardware rate limiting

You can specify resource limits used by an OpenFlow instance. Each OpenFlow instance has independent rate-limiters that can be set separately.

Syntax

openflow instance <instance-name> limit {hardware-rate | software-rate}

instance-name

OpenFlow instance name.

hardware-rate

Limit the bandwidth that an OpenFlow instance can utilize. The hardware-rate is in kbps.

Range: 0 - 10,000,000

Default: 0

software-rate

Configure the OpenFlow instance packet rate limit. The software-rate is in pps.

Limits the number of packets per second per module that this instance can send to the software path.

Range: 0 - 10000

Default: 100

NOTE:

Increasing the software rate limit increases CPU consumption and may impact system performance.

If the software rate limit is specified beyond 1000 pps, the following warning message is displayed: Increasing the software rate limit would increase CPU consumption and may impact the system performance.
