Configuring QoS

All CFM traffic is queued to the default class because there is no class based on CoS.

Example 2
This example shows how to mark the CoS of CPU-generated IP traffic (including IP-SLA and TWAMP) based on the
DSCP value in the packet and to configure egress queuing based on the CoS value.

All CPU-generated IP traffic queues on the egress port, based on the IP DSCP value and the configured output policy
map called
output-policy .

All IP SLA or TWAMP probes with the DSCP value ef to simulate voice traffic are assigned to the voice class.

All IP SLA or TWAMP probes with the DSCP values af41 , af42 and af43 to simulate video traffic are assigned to the
video class.

All IP control protocol traffic with the DSCP values 48 and 56 are assigned to the network-internetwork-control class.

The rest of the IP traffic is assigned to the default class.

All CPU-generated non-IP traffic with CoS 5 is assigned to the voice class.

All CPU-generated non-IP traffic with CoS 3 is assigned to the video class.
