When an egress-rate sub-rate value is given, the network queue (on network ports or access uplink ports) rates that are specified using percentages will use the egress-rate value instead of the port bandwidth (if egress rate is lesser than port bandwidth) to configure the appropriate queue rates. Configuration of egress port rate to different values will result in a corresponding dynamic adjustment of rates for the queues configured on network ports, or access uplink ports.
When the egress-rate sub-rate value is set, CBS/MBS of the associated network queues will not change.
