Each command is listed, in detail, in the following sections.
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>]}
Description The config bandwidth_control 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.
Restrictions Only Administrator-level users can issue this command.
Example usage:
To configure bandwidth control:
DES-3028P: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.
DES-3028P:4#
show bandwidth_control
Purpose Used to display the bandwidth control table.
Syntax
show bandwidth_control {<portlist>}
Description The show bandwidth_control command displays the current
bandwidth control configuration on the Switch, on a port-by-port
basis.
Parameters
<portlist>  Specifies a port or range of ports to be viewed.
Restrictions None.
Example usage:
To display bandwidth control settings:
