cpu traffic qos dscp
Examples This example shows how to configure the DSCP value of CPU-generated packets:
Switch(config)# cpu traffic qos dscp 36
This example shows how to configure the switch to trust the DSCP value of incoming CPU-generated
packets:
Switch(config)# cpu traffic qos dscp trust
This example shows how to mark the DSCP of CPU-generated IP traffic (including IP-SLA and
TWAMP) based on the DSCP value in the packet.
The example has these results:
• All IP traffic with the DSCP value 0 is assigned DSCP value 30.
• All IP traffic with the DSCP values af41 (34), af42 (36) and af43 (38) are assigned DSCP value 48.
• All other IP and non-IP traffic is processed by the default configuration.
Maps:
Switch(config)# mls qos
Switch(config)# mls qos map dscp-mutation mapname 0 to 30
Switch(config)# mls qos map dscp-mutation mapname 34 36 38 to 48
CPU QoS:
Switch(config)# cpu traffic qos dscp dscp-mutation mapname
