This section describes commands used to configure Layer 3 and 4 traffic priority
mapping on the switch.

Command
qos map cos-dscp
qos map dscp-mutation

* The default settings used for mapping priority values to internal DSCP values and back to the
hardware queues are designed to optimize priority services for the majority of network
applications. It should not be necessary to modify any of the default settings unless a queuing
problem occurs with a particular application.
This command maps CoS/CFI values in incoming packets to per-hop behavior and
drop precedence values for priority processing. Use the no form to restore the
default settings.
Syntax
qos map cos-dscp phb drop-precedence from cos0 cfi0...cos7 cfi7
no qos map cos-dscp cos0 cfi0...cos7 cfi7
phb - Per-hop behavior, or the priority used for this router hop. (Range: 0-7)
drop-precedence - Drop precedence used for controlling traffic congestion.
(Range: 0 - Green, 3 - Yellow, 1 - Red)
cos - CoS value in ingress packets. (Range: 0-7)
cfi - Canonical Format Indicator. Set to this parameter to "0" to indicate that
the MAC address information carried in the frame is in canonical format.
(Range: 0-1)
