Changing the IP precedence –> DSCP mappings
The IP precedence –> DSCP mappings are used if the trust level is IP Precedence as set by the
qos-tos trust command.
To change the IP precedence –> DSCP mappings, enter commands such as the following at the
global CONFIG level of the CLI.
Brocade(config)# qos-tos map ip-prec-dscp 0 32 24 48 16 8 56 40
Brocade(config)# ip rebind-acl all
This command configures the mappings displayed in the IP Precedence-DSCP map portion of the
QoS information display.
Brocade(config-if-1/1)# show qos-tos

Syntax: [no] qos-tos map ip-prec-dscp dscp1 dscp2 dscp3 dscp4 dscp5 dscp6 dscp7 dscp8
The dscp1 ... dscp8 parameters specify the DSCP values you are mapping to the IP precedence
values. You must enter DSCP values for all eight IP precedence values, in order from IP precedence
value 0 – 7.
NOTE
To place a qos-tos mapping change into effect, you must enter the ip rebind-acl all command at the
global CONFIG level of the CLI after making the mapping change. This applies to mappings that are
configured using the qos-tos map command.
Changing the DSCP –> DSCP mappings
To change a DSCP –> DSCP mapping, enter a command such as the following at the global CONFIG
CLI level.
Brocade(config)# qos-tos map dscp-dscp 0 10
Brocade(config)# ip rebind-acl all
This command changes the mapping of DSCP value 0 from 0 to 10.
Syntax: [no] qos-tos map dscp-dscp old-dscp-value [old-dscp-value...]
to new-dscp-value [new-dscp-value...]
You can change up to eight DSCP values in the same commend. Make sure you enter the old
values and their new values in the same order.
NOTE
To place a qos-tos mapping change into effect, you must enter the ip rebind-acl all command at the
global CONFIG level of the CLI after making the mapping change. This applies to mappings that are
configured using the qos-tos map command.
