qos map dscp-mutation
Creates a DSCP mutation by remapping the incoming DSCP value of the ingress packet to outgoing
DSCP values.
Synopsis qos map dscp-mutation name
no map qos dscp-mutation name
mark ingress dscp values to egress dscp value
Operands name Name of dscp-mutation map
ingress dscp values Range of input DSCP values
egress dscp values Output DSCP value
Defaults DSCP mutation is not enabled.
Command Modes dscp-mutation mode for the dscp-mutation map
Global configuration mode
Description Use this command to create a QoS dscp-mutation map. Use this command to remap the incoming
DSCP values of the ingress packet to an egress DSCP value.
Usage Guidelines Enter qos dscp-mutation name while in configuration mode for a specific interface to apply the
dscp-mutation map to that interface. When you enter qos map dscp-mutation, the system is
placed in dscp-mutation mode for the configured map. At this point, you can map ingress DSCP
values to egress DSCP values using the mark command.
Enter no qos dscp-mutation name while in interface configuration mode to remove the map from
that interface.
Enter no map dscp-mutation name while in global configuration mode to remove the
dscp-mutation map.
NOTE
This command is only supported on VDX 8770-4, VDX 8770-8, and later switches.
Examples To create a QoS DSCP-mutation map and place system into dscp-mutation mode:
switch(config)# qos map dscp-mutation test
switch(dscp-mutation-test)#
To map an ingress DSCP value to egress DSCP values while in dscp-mutation mode:
switch(dscp-mutation-test)# mark 1,3,5,7 to 9
To map multiple ingress DSCP values to egress DSCP values while in dscp-mutation mode:
switch(dscp-mutation-test)# mark 1,3,5,7 to 9
switch(dscp-mutation-test)# mark 11,13,15,17 to 19
switch(dscp-mutation-test)# mark 12,14,16,18 to 20
switch(dscp-mutation-test)# mark 2,4,6,8 to 10
To remove a QoS DSCP-mutation map while in global configuration mode:
switch(config)# no qos map dscp-mutation test
