Important:

the "lower-ip-precedence" option may also override the configuration of the
in the Subscriber Configuration mode). Therefore, it is recommended that command not be used when
specifying this option.
Step 2
Verify the subscriber profile configuration by applying the following example configuration:
context <context_name>
show subscriber configuration username <user_name>
Step 3
Save your configuration to flash memory, an external memory device, and/or a network location using the Exec mode

Configuring APN for Traffic Shaping in 3GPP Networks
This section provides information and instructions for configuring APN template's QoS profile in support of Traffic
Shaping.
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 values for the 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 following table.
Table 46. Permitted Values for Committed and Peak Data Rates in GTP Messages
Value (bps)
From 1000 to 63,000
From 64,000 to 568,000
From 576,000 to 8,640,000
From 8,700,000 to 16,000,000
Step 1
Set parameters by applying the following example configurations.
