shaping attributes must contain the same metric or unit of measure.

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 both lossy and lossless traffic. 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.
string Enter the WRED profile name. It is a string of up to 32 characters. Or use one of the five
pre-defined WRED profile names. Pre-defined Profiles: wred_drop, wred-ge_y,
wred_ge_g, wred_teng_y, wred_teng_. This parameter applies only if you specify a
weight factor.
Default All queues on backplane ports operate in tail-drop (best-effort traffic) mode by default. There is no default WRED
green or yellow profile. The default weight is 0.
