Configuring EXP Value Maps
These sections describe how EXP values are mapped to other values:
• Configuring an Ingress-EXP to Internal-DSCP Map, page 42-31
• Configuring a Named Egress-DSCP to Egress-EXP Map, page 42-31
Configuring an Ingress-EXP to Internal-DSCP Map
To configure an ingress-EXP to internal-DSCP map, perform this task:
This example shows how to configure an ingress-EXP to internal-DSCP map:
Router(config)# mls qos map exp-dscp 43 43 43 43 43 43 43 43
Router(config)#
This example shows how to verify the configuration:
Router(config)# show mls qos map exp-dscp
Exp-dscp map:
exp: 0 1 2 3 4 5 6 7
------------------------------------
dscp: 43 43 43 43 43 43 43 43
Configuring a Named Egress-DSCP to Egress-EXP Map
To configure a named egress-DSCP to egress-EXP map, perform this task:
This example shows how to configure a named egress-DSCP to egress-EXP map:
Router(config)# mls qos map dscp-exp 20 25 to 3
Router(config)#
Command Purpose
Step 1
Router(config)# mls qos map exp-dscp
values
Configures the ingress-EXP value to internal-DSCP map.
You must enter eight DSCP values corresponding to the
EXP values. Valid values are 0 through 63.
Router(config)# no mls qos map exp-dscp
Reverts to the default map.
Step 2
Router(config)# end
Exits configuration mode.
Step 3
Router# show mls qos maps
Verifies the configuration.
Command Purpose
Step 1
Router(config)#
mls qos map dscp-exp
dscp_values
to
exp_values
Configures a named egress-DSCP to egress-EXP map.
You can enter up to eight DSCP values at one time to a
single EXP value. Valid values are 0 through 7.
Router(config)# no mls qos map dscp-exp
Reverts to the default map.
Step 2
Router(config)# end
Exits configuration mode.
Step 3
Router# show mls qos maps
Verifies the configuration.
