config bandwidth_control
Purpose
Used to configure bandwidth control on a port by-port basis.
Syntax
config bandwidth_control [<portlist>] {rx_rate [no_limit | <value 64-
1024000>] | tx_rate [no_limit <value 64-1024000>]} (1)
Description
This command is used to configure bandwidth on a port by-port basis.
Parameters
<portlist> − Specifies a port or range of ports to be configured.
rx_rate − Specifies that one of the parameters below (no_limit or
<value 64-1024000>) will be applied to the rate at which the above
specified ports will be allowed to receive packets
no_limit − Specifies that there will be no limit on the rate of packets
received by the above specified ports.
<value 64-1024000> − Specifies the traffic limit, in Kbits, that the
above ports will be allowed to receive.
tx_rate − Specifies that one of the parameters below (no_limit or
<value 64-1024000>) will be applied to the rate at which the above
specified ports will be allowed to transmit packets.
no_limit − Specifies that there will be no limit on the rate of packets
received by the above specified ports.
<value 64-1024000> − Specifies the traffic limit, in Kbits, that the
above ports will be allowed to receive.
Actual rate = |rate entered/ minimum granularity|* minimal granularity,
for example: 62.5=|100/62.5|*62.5”
|number| implies the closest smaller integer.
Restrictions
Only Administrator-level users can issue this command.
Example usage:
To configure bandwidth control:
DES-3200-28:4#config bandwidth_control 1 rx_rate 64
Command: config bandwidth_control 1 rx_rate 64
Note: To perform precise bandwidth control, it is required to enable the
flow control to mitigate the retransmission of TCP traffic.
Success.
