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
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_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.

Usage Information
You can configure only service pool 0. The pool, service0, is used for lossy queues.
A WRED profile contains a set of attributes, such as the minimum and maximum threshold values, and the
maximum drop rate for the received packets. You can add or remove WRED parameter configurations for one or
more shared service pools using a single command. The
service-pool wred
command is similar in usage and
working to the
service-class bandwidth-percentage
queue-id
command.
