must be an integer from 1 through 6000000.
Important:
It is recommended that the minimum value of this parameter be configured to the greater of the
following two values: 1) three times greater than packet MTU for the subscriber connection, OR 2) 3 seconds worth of
token accumulation within the “bucket” for the configured peak-data-rate. In addition, if the committed-data-rate
parameter is specified, the burst-size is applied to both the committed and peak rates.

auto-readjust [ duration
dur
]
keyword provides the option to calculate the Burst size dynamically
while configuring the rate-limit. Whenever this keyword is enabled to calculate burst size, the GGSN QoS
negotiated rate is enforced for this calculation.
Whenever there is a change in the rates (due to a QoS update), the burst sizes will be updated accordingly.
This keyword also provides two different burst sizes. One burst size for peak rate and another for committed
rate.
By default this keyword is disabled.

duration
dur
describes the duration of burst in seconds. If duration is not specified this keyword will use 1
second as default value.
dur
must be an integer between 1 through 30.
exceed-action { drop | lower-ip-precedence | transmit }
The action to take on the packets that exceed the committed-data-rate but do not violate the peak-data-rate.
The following actions are supported:
The following actions are supported:
drop
: Drop the packet.
lower-ip-precedence
: Transmit the packet after lowering the ip-precedence.
transmit
: Transmit the packet.
violate-action { drop | lower-ip-precedence | shape [ transmit-when-buffer-full ]
| transmit }
| transmit }
The action to take on the packets that exceed both the committed-data-rate and the peak-data-rate. The
following actions are supported:
following actions are supported:
drop
: Drop the packet.
lower-ip-precedence
: Transmit the packet after lowering the IP precedence.
shape [ transmit-when-buffer-full ]
: This keyword is not supported in this release.
Important:
Traffic Shaping is not supported on the GGSN, P-GW, or SAEGW.
transmit
: Transmit the packet.
+
More than one of the above keywords can be entered within a single command.
Usage
This command configures APN quality of service (QoS) through traffic policing. This command enables the
actions on subscriber flows exceeding or violating the allowed peak/committed data rate.
actions on subscriber flows exceeding or violating the allowed peak/committed data rate.
Important:
This command is not intended for bearer level policing
