service-pool wred
A global buer pool that is a shared buer pool accessed by multiple queues when the minimum guaranteed buers for the queue are
consumed can be congured on the S6000 and Z9000 platforms.
Create a global buer pool that is a shared buer pool accessed by multiple queues when the minimum guaranteed buers 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 ow control (PFC)) queues. You can enable WRED and ECN
conguration on the global service-pools. You can dene WRED proles 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 Dene 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 buer 1 (default service-pool for PFC trac) .
pool1 Service-pool buer 0 (default service-pool for both lossy and lossless trac. trac).
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 prole name. It is a string of up to 32 characters. Or use one of the ve
pre-dened WRED prole names. Pre-dened Proles: 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-eort trac) mode by default. There is no default WRED
green or yellow prole. The default weight is 0.

Version Description
9.8(1.0) Introduced on the Z9100-ON.
9.7(0.0) Introduced on the S6000-ON.
9.3.0.0 Introduced on the S6000 and Z9000 platforms
Usage Information
You can congure only service pools 0 and 1 because the Dell Networking OS uses only these two service pools.
The pool, service0, is used for lossy queues and the pool, service1, is used for lossless (PFC) queues in all the
platforms.
