Usage
This command configures the APN quality of service (QoS) data rate shaping through traffic policing/shaping. This
command specifies the actions to take on subscriber flows exceeding or violating allowed peak/committed data rates.
The shaping function also provides an enhanced function to buffer the excessive user packets and send them to the
subscriber when subscriber traffic drops below the committed or peak data rate limit.

Important:
The buffering of user packets in traffic shaping does not apply for real-time traffic.
Important:
If the exceed/violate action is set to “lower-ip-precedence”, this command may override the
configuration of the
ip qos-dscp
command in the GGSN service configuration mode for packets from the GGSN to
the SGSN. In addition, the GGSN service
ip qos-dscp
command configuration can override the APN setting for
packets from the GGSN to the Internet. Therefore, it is recommended that command not be used in conjunction with this
action.
action.
The command can be entered multiple times to specify different combinations of direction and class. If this command is
not configured at all, the GGSN does not perform traffic policing or QoS negotiation with the SGSN (i.e. it accepts all
of the SGSN-provided values for the PDP context.

Important:
This command should be used in conjunction with the
max-contexts
command to limit the
maximum possible bandwidth consumption by the APN.
Default Values:
To calculate the burst size dynamically a new optional keyword
auto-readjust
[
duration
dur
] is provided with
burst-size
keyword. By default the burst size is fixed if defined in bytes with this command. In other words
irrespective of the rate being enforced, burst-size fixed as given in the
burst-size
bytes
parameter.
For the need of variable burst size depending on the rate being enforced this new keyword
auto-readjust
[
duration
dur
] is provided. Use of this keyword enables the calculation of burst size as per token bucket algorithm
calculation as T=B/R, where T is the time interval, B is the burst size and R is the Rate being enforced.
It also provides different burst size for Peak and Committed data rate-limiting.
If
auto-readjust
keyword is not used a fixed burst size must be defined which will be applicable for peak data rate
and committed data rate irrespective of rate being enforced.
If
auto-readjust
keyword is provided without specifying the duration a default duration of 1 second will be taken for
burst size calculation.
