Notes:
There are numerous keyword options associated with
command.
Repeat for each additional subscriber to be configured.
Important:
If the exceed/violate action is set to ―lower-ip-precedence‖, the TOS value for the outer packet
becomes ―best effort‖ for packets that exceed/violate the traffic limits regardless of what the
command in the Subscriber Configuration mode is configured to. In addition, the ―lower-ip-precedence‖
option may also override the configuration of the
command (also 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:
Step 3
Save the configuration as described in the Verifying and Saving Your Configuration chapter.
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.
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.
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.
