qos map dscp-cos
Creates a QoS map for performing DSCP-to-CoS mapping. This configures a DSCP-to-CoS map on
the ingress interface.
Synopsis qos map dscp-cos name
no qos map dscp-cos name
mark ingress dscp values to egress cos value
Operands name Name of dscp-cos map
ingress dscp values Range of input DSCP values
egress dscp values Output CoS value
Defaults DSCP-to-CoS mutation is not enabled.
Command Modes dscp-cos mode for the QoS map
Global configuration mode
Description Use this command to create and remove QoS dscp-cos maps, which remap the incoming DSCP
values of the ingress packet to egress CoS 802.1P values.
Usage Guidelines When you enter qos map dscp-cos, the system is placed in dscp-cos mode for the configured map.
At this point, you can map ingress DSCP values to egress CoS values using the mark command.
Enter qos dscp-cos name while in configuration mode for a specific interface to apply the
DSCP-CoS map to that interface.
Enter no qos dscp-cos name while in the interface configuration mode to remove the map from
the interface.
Enter no map dscp-cos name while in global configuration mode to remove the DSCP-CoS map.
Examples To create a QoS DSCP-CoS map and place system into dscp-cos mode:
switch(config)# qos map dscp-cos test
switch(dscp-cos-test)#
To map an ingress DSCP value to egress CoS values while in dscp-cos mode:
switch(dscp-cos-test)# mark 1,3,5,7 to 3
To map multiple ingress DSCP values to egress CoS values while in dscp-cos mode:
switch(dscp-mutation-test)# mark 1,3,5,7 to 9
switch(dscp-mutation-test)# mark 11,13,15,17 to 5
switch(dscp-mutation-test)# mark 12,14,16,18 to 6
switch(dscp-mutation-test)# mark 2,4,6,8 to 7
To remove a QoS DSCP-CoS map while in global configuration mode:
switch(config)# no qos map dscp-cos test
