Important:
System measurements for this value exclude the GTP and outer packet headers. In addition, some
traffic classes have both a committed rate and a peak rate, while other traffic classes have just a peak rate. If a
committed rate is not applicable (such as, the traffic class is background or interactive), an error occurs if this option is
configured. If the committed-rate is applicable (such as, the traffic class is conversational or streaming), the values
supplied by the SGSN are used if this option is not configured.

peak-data-rate

Default: See the Usage section for this command
Specifies the peak data-rate for the subscriber in bps (bits per second).
Specifies the peak data-rate for the subscriber in bps (bits per second).
bps
must be an integer from 1 through 16000000 for the downlink direction or 1 through 8640000 for the
uplink direction. The value must also correspond to one of the permitted values identified in the tables below.
If a non-permitted value is entered for this parameter, the system rounds the value to the nearest lower
supported value, except in the case where value is less than 1,000 bps. In this case, the system rounds the
value to 1,000 bps.

value to 1,000 bps.
Usage
This command configures the APN quality of service (QoS) profile. This feature enables configuring and
enforcing bandwidth limitations on individual PDP contexts of a particular traffic class. Traffic classes are
defined in 3GPP TS 23.107 and are negotiated during PDP context activation. Bandwidth enforcement is
configured and enforced independently for the downlink and the uplink directions.
The profile information is sent to the SGSN(s) in response to GTP Create/Update PDP Context Request
messages. If the QoS profile requested by the SGSN is lower than the configured QoS profile configured, the
profile requested by the SGSN is used. If the QoS profile requested by the SGSN is higher, the configured
rates are used.
Note that the values for the uplink/downlink committed-data-rate and peak-data-rate parameters are
exchanged in the GTP messages between the GGSN and the SGSN. Therefore, the values used may be lower
than the configured values. When negotiating the rate with the SGSN(s), the system convert this to a value
that is permitted by GTP as shown in the tables below.

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.
Additional information on the QoS traffic shaping functionality is located in the System Administration
Guide.
