When an egress-rate sub-rate value is provided, the access-uplink port egress queue rates that are specified using percentages use the egress-rate value instead of the port bandwidth (if egress rate is less than port bandwidth) to configure the queue rates. Configuring the egress port rate to different values results in a corresponding dynamic adjustment of rates for the egress queues configured on the access-uplink ports.
When the egress-rate sub-rate value is set, the CBS and MBS of the associated network queues do not change.
