Users Guide

You can congure 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 prole 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 congurations 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
Dell(conf-wred) #wred thresh-1
Dell(conf-wred) #threshold min 100 max 200 max-drop-rate 40
Dell(conf-wred) #wred thresh-2
Dell(conf-wred) #threshold min 300 max 400 max-drop-rate 80
Dell(conf) #service-pool wred green pool0 thresh-1 pool1 thresh-2
Dell(conf) #service-pool wred yellow pool0 thresh-3 pool1 thresh-4
Dell(conf) #service-pool wred weight pool0 11 pool1 4
DSCP Color Map Commands
The DSCP color map allows you to set the number of specic DSCP values to yellow or red. Trac marked as yellow delivers trac 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. Trac marked
as red (high drop precedence) is dropped.
dscp
Sets the number of specic DSCP values for a color map prole to yellow or red.
Syntax
dscp {yellow | red} [list-dscp-values]
To remove a color policy map prole, use the no dscp {yellow | red} [dscp-list] command.
Parameters
Yellow Enter the yellow keyword. Trac marked as yellow delivers trac 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. Trac marked as red is dropped.
dscp-list Enter a list of IP DSCP values. The dscp-list parameter species the full list of IP DSCP
value(s) for the specied 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
