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] buffer-pool wred {green | weight | yellow} {[pool0 number/
string] || [pool1 number/string]}
Parameters
buffer-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.
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.
