85-3 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> {{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> - Enter a range of ports to be configured.
all - Specifies to set all ports in the system. If no parameter is specified, the system will set all
the ports.
<cos_id_list> - Enter a list of priority queues.
min_rate - Specifies 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> - Enter 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.
max_rate - Specifies 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> - Enter 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.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
Example
To configure the maximum rate to be 100 on queue 1 for ports 1 to 10:
DGS-3620-28SC:admin#config per_queue bandwidth_control ports 1:1-1:10 1
max_rate 100
Command: config per_queue bandwidth_control ports 1:1-1:10 1 max_rate 100
Granularity: TX: 8. Actual Rate: MAX: 96.
