Connectivity Guide

You can configure the weight for the WRED average queue size for service1, which is the only the
platform in which PFC is supported for this service pool.
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.
Example
DellEMC(conf-wred) #wred thresh-1
DellEMC(conf-wred) #threshold min 100 max 200 max-drop-rate 40
DellEMC(conf-wred) #wred thresh-2
DellEMC(conf-wred) #threshold min 300 max 400 max-drop-rate 80
DellEMC(conf) #service-pool wred green pool0 thresh-1 pool1 thresh-2
DellEMC(conf) #service-pool wred yellow pool0 thresh-3 pool1 thresh-4
DellEMC(conf) #service-pool wred weight pool0 11 pool1 4
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 available bandwidth or drop the packet due to no ability
to send. Traffic marked as red (high drop precedence) is dropped.
dscp
Sets the number of specific DSCP values for a color map profile to yellow or red.
Syntax
dscp {yellow | red} [list-dscp-values]
To remove a color policy map profile, use the no dscp {yellow | red} [dscp-list] command.
Parameters
Yellow Enter the yellow keyword. Traffic marked as yellow delivers traffic to the egress
queue which either transmits the packet if it has available bandwidth or drops the
packet due to no ability to send.
Red Enter the red keyword. Traffic marked as red is dropped.
dscp-list Enter a list of IP DSCP values. The dscp-list parameter specifies the full list of IP
DSCP value(s) for the specified color. Each DSCP value in a list is separate values
by commas – no spaces (1,2,3) or indicates a list of values separated by a hyphen
(1-3). Range is 0 to 63.
Defaults None
