84-1 config bandwidth_control
Description
This command is used to configure the port bandwidth limit control.
Format
config bandwidth_control [<portlist> | all] {rx_rate [no_limit | <value 8-10240000>] | tx_rate
[no_limit | <value 8-10240000>]}
Parameters
<portlist> - Specify a range of ports to be configured.
all – Specify that all the ports will be used for this configuration.
rx_rate - (Optional) Specify the limitation applied to receive data rate.
no_limit - Indicates there is no limit on receiving bandwidth of the configured ports. An integer
value from m to n sets a maximum limit in Kbits/sec. The actual bandwidth will be an
adjusted value based on the user specified bandwidth. The actual limit may be equal to the
user specified limit, but will not exceed it. The actual limit recognized by the device, will be
displayed when the command is executed.
<value 8-10240000> - Enter the receiving data rate here. This value must be between 8 and
10240000.
tx_rate - (Optional) Specify the limitation applied to transmit data rate.
no_limit - Indicates there is no limit on port tx bandwidth. An integer value from m to n sets a
