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.
service-pool wred
A global buffer pool that is a shared buffer pool accessed by multiple queues when the minimum
guaranteed buffers for the queue are consumed can be configured on the S6000 and Z9000 platforms.
Create a global buffer pool that is a shared buffer pool accessed by multiple queues when the minimum
guaranteed buffers for the queue are consumed. S4810, S4820T, S6000, and Z9000 platforms support
four global service-pools in the egress direction. Two service pools are used—one for lossy queues and
the other for lossless (priority-based flow control (PFC)) queues. You can enable WRED and ECN
configuration on the global service-pools. You can define WRED profiles and weight on each of the
global service-pools for both lossy and lossless (PFC) service-pools.
Syntax [No] service-pool wred {green | weight | yellow} {[pool0
number/string] | [pool1 number/string]}
Parameters service-pool Define the mapping between the service class and policy-
based QoS or routing.
wred Specify WRED curve parameters for a queue.
green Specify green (low) drop precedence to a queue.
weight Specify a weight factor to a queue.
yellow Specify yellow (medium) drop precedence to a queue.
pool0 Service-pool buffer 1 (default service-pool for PFC traffic) .
pool1 Service-pool buffer 0 (default service-pool for lossy traffic).
number Enter a weight for the queue as a number in the range of 1 to
15. This parameter applies only if you specify the green or
yellow drop precedence.
