Platform Control-Plane-Prioritization Rate - Allied Telesis SwitchBlade x908 Series Software Reference Manual

platform control-plane-prioritization rate

The CPU protection feature ensures that different traffic types can share the CPU effectively.
Use this command to set the maximum traffic rate on the CPU port to limit the CPU getting
overloaded with unnecessary data packets that may result in poor performance of the control
plane, for example, CLI console lock up or control packet loss following a broadcast storm.
The default rate limiting value is set to transmit the packets to the CPU at 60 Mbps. The CPU
port uses the WRR (Weighted Round Robin) scheduler with appropriate weights assigned.
Use the no platform control-plane-prioritization command to restore the rate limiting
on the CPU port to the default value of 60 Mbps. Note only integer values are accepted for
rate limits. Set the rate to 0 using platform control-plane prioritization rate to disable
CPU protection.
