Chapter 6 Policy-enabled networks and QoS 207
Reference for the Business Policy Switch 2000 Command Line Interface
Using the CLI, you set shapers. If you want to shape traffic at the egress point,
configure the committed rate, burst rate, burst duration, and queue depth for each
shaper.
qos shaper command
The qos shaper command creates or deletes a QoS shaper. The syntax for the
qos shaper command is:
qos shaper <shapeid> {create [name <shapername>] shape-rate
<rate> max-burst-rate <burstrate> [max-burst-duration
<burstdur>] queue-size <1|2|4|8|16>|delete}
The qos shaper command is in the config command mode.
Table 122 describes the parameters and variables for the
qos shaper command.
Table 122 qos shaper command parameters and variables
Parameters and variables Description
<shapeid> Enter an integer to specify the QoS shaper; range is 1 to 65535.
name <shapername> Assigns a name to the QoS shaper with the designated shaper ID. Enter
name for shaper; maximum is 16 alphanumeric characters.
shape-rate <rate> Specifies maximum rate that traffic will be transmitted over a given duration
Enter the rate in Kbps; range is 1 to 42949672955 Kbps.
Note:
You must specify a value that is a multiple of 64 Kbps; O is invalid.
max-burst-rate <burstrate> Specifies the largest burst of traffic that can be transmitted without a
shaping delay. Used in calculating the committed burst size. Enter the burst
size in bytes; range is 0 to 42949672955 bytes.
max-burst-duration
<burstdur>
Specifies the amount of time that the largest burst of traffic can be
transmitted without a shaping delay. Enter the burst duration in ms; range is
0 to 42949672955 ms.
queue-size <1|2|4|8|16> Specifies the number of packets that can exceed the largest burst of traffic
allowed and still be queued for transmission.
delete Deletes the specified shaper.
