Usage Information

Example

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.

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.

CONFIGURATION mode

VersionDescription

9.7(0.0)

Introduced on the S6000-ON.

9.3.0.0Introduced on the S6000 and Z9000 platforms

You can configure 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.

You can configure the weight for the WRED average queue size for service1 on the S6000 Switch, which is the only platform in which PFC is supported for this service pool. On the Z9000 Switch, only service0 can be configured because it does not support PFC.

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-classbandwidth-percentagequeue-idcommand.

DSCP Color Map Commands

The DSCP color map allows you to set the number of specific DSCP values to yellow or red. Traffic marked as yellow delivers traffic to the egress queue which will either transmit the packet if it has
