History
Version 9.3.0.0 Added support for committed rate and committed burst size,
and for configuration of rate limits on the S6000 platform.
Usage
Information
If you specify the pps keyword after the rate-shape command, the peak rate, peak
burst, committed rate and committed burst are all considered to be values as a
measure of packets. If you do not specify the pps or kbps keyword, the peak and
committed rate settings are considered to be values in Mbps. Similarly, if you enter
the kbps keyword, the peak and committed rate settings are treated as values in
Kbps.
You cannot configure the committed rate settings to use a different metric or unit
from the metric that is set for peak rate attributes because when you use the
rate-shape kbps command, it denotes the metric for peak and committed rate
attributes). Similarly, if you use the rate-shape pps option , it denotes the metric
for peak rate and committed rate attributes.
If you attempt to define the committed rate to be less than the peak rate, an error
message is displayed stating that the peak rate cannot be lower than the
committed rate. You can configure all the rate shaping parameters to be either in
bytes or packets measure for each queue. The rate and burst parameters for both
minimum and maximum settings for a queue can be either in packets or bytes. You
cannot configure some of rate shaping attributes to be in bytes measure and the
remaining rate shaping attributes to be in packets measure; all the rate shaping
attributes must contain the same metric or unit of measure.
Example
Dell (conf-qos-policy-out) #rate-shape pps 100 100 peak pps
1000 200
Dell (conf-qos-policy-out) #rate-shape kbps 1024 100 peak kbps
102400 75
Dell (conf-qos-policy-out) # rate-shape 100 100 peak 1000 750
Dell(conf-qos-policy-in)#rate-police 100 25 peak 80 500
% Error: Peak rate cannot be less than committed rate.
buffer-stats-snapshot
Enable the buffer statistics tracking utility and enter the Buffer Statistics Snapshot configuration mode.
You must enable this utility to be able to configure the parameters for buffer statistics tracking. This utility
is supported on the S6000 platform.
