Cisco Cisco Packet Data Interworking Function (PDIF)
Subscriber Configuration Mode Commands
▀ qos traffic-shape
▄ Command Line Interface Reference, StarOS Release 17
8830
Important:
If the exceed or violate action is set to “lower-ip-precedence”, the TOS value for the outer packet
becomes “best effort” for packets that exceed or violate the traffic limits regardless how the
ip user-datagram-tos
copy
command is configured. In addition, the “lower-ip-precedence” option may also override the configuration of the
ip qos-dscp
command. Therefore, this command should not be used when specifying this option.
Details on the QoS traffic policing functionality is located in the System Administration Guide.
Example
The following command sets an uplink peak data rate of
128000
bps and lowers the IP precedence when the
committed-data-rate and the peak-data-rate are exceeded:
qos traffic-shape direction uplink peak-data-rate 12800 violate-action
lower-ip-precedence
lower-ip-precedence
The following command buffers the excess user packets when the subscriber traffic violates the configured
peak-data-rate
peak-data-rate
256000
bps in downlink direction. Once the peak/committed data rate for that subscriber goes
below the configured limit it transmit them. It also transmits them if buffer memory is full:
qos traffic-shape direction downlink peak-data-rate 256000 violate-action
buffer transmit-when-buffer-full
buffer transmit-when-buffer-full
