Important:
It is recommended that this parameter be configured to at least the greater of the following two
values: 1) three times greater than packet MTU for the subscriber connection, OR 2) three seconds worth of token
accumulation within the “bucket” for the configured peak-data-rate.
accumulation within the “bucket” for the configured peak-data-rate.
committed-data-rate
bps
Default: 144000
Specifies the committed data rate (guaranteed-data-rate) in bits per second (bps).
Specifies the committed data rate (guaranteed-data-rate) in bits per second (bps).
bps
must be an integer from 0 through 4294967295).
exceed-action
{
drop
|
lower-ip-precedence
|
transmit
}
Default: lower-ip-precedence
Specifies the action to take on packets that exceed the committed-data-rate but do not violate the peak-data-
rate. The following actions are supported:
Specifies the action to take on packets that exceed the committed-data-rate but do not violate the peak-data-
rate. The following actions are supported:
drop
: Drops the packet
lower-ip-precedence
: Transmits the packet after lowering the ip-precedence
transmit
: Transmits the packet
peak-data-rate
bps
Default: 256000
Specifies the peak data-rate for the subscriber in bits per second (bps).
Specifies the peak data-rate for the subscriber in bits per second (bps).

| transmit }
Default: See the Usage section for this command
The action to take on the packets that exceed both the committed-data-rate and the peak-data-rate. The
following actions are supported:
The action to take on the packets that exceed both the committed-data-rate and the peak-data-rate. The
following actions are supported:
drop
: Drops the packet
lower-ip-precedence
: Transmits the packet after lowering the IP precedence
buffer [transmit-when-buffer-full]
: Enables traffic shaping and buffers user packets when
subscriber traffic violates the allowed peak/committed data rate. The
[transmit-when-buffer-full]
keyword allows the packet to be transmitted when buffer memory is full.
transmit
: Transmits the packet
+
More than one of the above keywords can be entered within a single command.
no
Disables traffic policing for the specified direction for the current subscriber.
Usage
Use this command to provide the traffic shaping function to a subscriber in the uplink and downlink
directions. This feature is providing a traffic flow control different to QoS traffic policing. When a subscriber
violates or exceeds the peak data rate instead of dropping the packets, as in QoS traffic policing, this feature
buffers subscriber data packets and sends the buffered data when the traffic flow is low or not in congestion
state.
