69-1 config bandwidth_control
Description
This command is used to set the maximum limit for port bandwidth.
Format
config bandwidth_control [<portlist> | all] {rx_rate [no_limit | <value 64-10240000>] | tx_rate
[no_limit | <value 64-10240000>]}(1)
Parameters
<portlist> - Specify a range of ports to be configured.
all - Specify all ports.
rx_rate - (Optional) Specify the limitation of receive data rate.
no_limit - Specify to indicate there is no limit on port rx bandwidth.
<value 64-10240000> - Specify an integer value from 64 to 10240000 to set a maximum limit
in Kbits/sec. The specified bandwidth limit may be equaled but not exceeded. This exact
logical limit or token value is hardware determined. Note: 1 Kbit = 1000 bits, 1 Gigabit =
1000*1000 Kbits. Actual rate = (inputted rate/ 64) * 64.
tx_rate - (Optional) Specify the limitation of transmit data rate.
no_limit - Specify to indicate there is no limit on port tx bandwidth.
<value 64-10240000> - Specify an integer value from 64 to 10240000 to set a maximum limit
in Kbits/sec. The specified bandwidth limit may be equaled but not exceeded. This exact
logical limit or token value is hardware determined. Actual rate = (inputted rate/ 64) * 64.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
