Mapping between DSCP value and forwarding queue cannot be changed. However, mapping between
DSCP values and other properties can be changed as follows:

DSCP to internal forwarding priority mapping - You can change the mapping between the
DSCP value and the internal forwarding priority value from the default values shown in the above
tables. This mapping is used for CoS marking and determining the internal priority when the trust
level is DSCP. Refer to

Changing the DSCP to internal forwarding priority mappings

on page 34.

VLAN priority (802.1p) to hardware forwarding queue - You can change the mapping between the
802.1p value and hardware forwarding queue from the default value. Refer to

Changing the VLAN

priority 802.1p to hardwareforwarding queue mappings

on page 35

User-configurable scheduler profile

The user-configurable scheduler profile is a template that defines either the scheduling mechanism or
scheduling profile (weights assigned to the queues) or both for the egress queues. A configured user-
configurable scheduler profile for egress queues can be applied to any hardware device. The default
QoS is applicable to the entire system. If the scheduler profile is configured using the qos mech strict
command, all devices in the system will be configured with the strict priority. The user-configurable
scheduler profile is applicable only to the specific devices, leaving the remaining devices running default
QoS. On any device, the user-configurable scheduler profile has high priority over the default QoS. On
any device, user-configurable scheduler profile has high priority over the default QoS. The user-
configurable scheduler profile should be in line with default QoS commands in both stacking and stand-
alone systems.
