qos dscp-map

Description

Defines the local priority assigned to incoming packets for a specific IP differentiated services code point (DSCP) value. The DSCP map values are used to prioritize incoming packets when QoS trust mode is set to dscp.

To see the default DSCP map settings, use the following command:

switch# show qos dscp-map default
code_point local_priority cos color   name
---------- -------------- --- ------- ----
0          1                  green   CS0
1          1                  green
2          1                  green
3          1                  green
4          1                  green
5          1                  green
...
45         5                  green
46         5                  green   EF
47         5                  green
48         6                  green   CS6
...
61         7                  green
62         7                  green
63         7                  green

The no form of this command restores the assignments for a code point to the default setting.
