5-3 config per_queue bandwidth_control

Description

This command is used to set the bandwidth control for each specific egress queue on specified ports.

The maximum rate limits the bandwidth. When specified, packets transmitted from the queue will not

exceed the specified limit even if extra bandwidth is available. The specification of maximum rate is

effective regardless of whether the queue is operating in strict or Shaped Deficit Weighted Round

Robin (SDWRR) mode.

Format

config per_queue bandwidth_control {ports [<portlist> | all]} <cos_id_list 0-7> {{min_rate

[no_limit | <value 8-10240000>]} max_rate [no_limit | <value 8-10240000>]}(1)

Parameters

ports - (Optional) Specify a range of ports to be configured.

<portlist> - Specify a range of ports to be configured.

all - Specify to set all ports in the system. If no parameter is specified, the system will set all the

ports.

<cos_id_list 0-7> - Specify a list of priority queues. The priority queue number ranges from 0 to 7.

min_rate - Specify that one of the parameters below will be applied to the minimum rate that the

class specified above will be allowed to transmit packets at.

no_limit - Indicates there is no limit on egress queue of specified port bandwidth.

<value 8-10240000> - Specify an integer value from 8 to 10240000 to set a minimum limit in

Kbits/sec. The specified bandwidth limit may be equaled but not exceeded. The exact logical

limit or token value is hardware determined. Note: 1 Kbit = 1000 bits, 1 Gigabit = 1000*1000

Kbits.

max_rate - Specify one of the parameters below will be applied to the maximum rate that the class

specified above will be allowed to transmit packets at.

no_limit - Indicates there is no limit on egress queue of specified port bandwidth.

<value 8-10240000> - Specify an integer value from 8 to 10240000 to set a maximum limit in

Kbits/sec. The specified bandwidth limit may be equaled but not exceeded. The exact logical

limit or token value is hardware determined. Note: 1 Kbit = 1000 bits, 1 Gigabit = 1000*1000

Kbits.
