qos map cos-mutation
Creates a QoS map for performing CoS-to-CoS mutation.
Synopsis qos map cos-mutation name cos0 cos1 cos2 cos3 cos4 cos5 cos6 cos7
no qos map cos-mutation name
Operands name Specifies a unique name across all CoS-to-CoS mutation QoS maps defined
within the system. If the named CoS-to-CoS mutation QoS map does not exist,
then it is created. If the named CoS-to-CoS mutation QoS map already exists,
then it is updated and new mapping is automatically propagated to all
interfaces bound to the QoS map.
cos0 Sets the outbound CoS value for all packets with inbound CoS 0.
cos1 Sets the outbound CoS value for all packets with inbound CoS 1.
cos2 Sets the outbound CoS value for all packets with inbound CoS 2
cos3 Sets the outbound CoS value for all packets with inbound CoS 3.
cos4 Sets the outbound CoS value for all packets with inbound CoS 4.
cos5 Sets the outbound CoS value for all packets with inbound CoS 5.
cos6 Sets the outbound CoS value for all packets with inbound CoS 6.
cos7 Sets the outbound CoS value for all packets with inbound CoS 7.
Defaults There are no CoS-to-CoS mutation QoS maps defined.
Command
Modes
Global configuration mode
Description Use this command to create a QoS map for performing CoS-to-CoS mutation. A CoS-to-CoS
mutation takes an inbound CoS value and maps it to an outbound CoS value. The inbound CoS
value is the user priority after any interface ingress QoS trust and interface default CoS policy have
been applied. The outbound CoS value is used in selecting Traffic Class and egress packet
marking. The default is no CoS-to-CoS mutation QoS maps defined. Use the no qos map
cos-mutation name command to delete the named CoS-to-CoS mutation QoS map. A QoS map can
only be deleted if it is not bound to any interface.
Usage
Guidelines
None
Examples To create a CoS-to-CoS mutation QoS map to swap CoS 4 and CoS 5 and apply it on an interface,
for example inbound CoS 4 is mapped to outbound CoS 5 and inbound CoS 5 is mapped to
outbound CoS 4; all other CoS values go through unchanged:
switch(config)#qos map cos-mutation test 0 1 2 3 5 4 6 7
