Configuring QoS Marking and Queuing for CPU-Generated Traffic
Beginning in privileged EXEC mode, follow these steps to configure marking and queuing of CPU-generated traffic. This
procedure is optional.
Command Purpose
1. configure terminal Enter global configuration mode.
2. Configure global table maps Refer to the Configuring Table Maps, page 608 .
3. cpu traffic qos cos { cos-value | cos
[table-map table-map-name ] | dscp
[table-map table-map-name ] | prec
[table-map table-map-name ]}
Mark traffic by setting a new CoS value or by specifying a table map.

For cos-value , enter a new CoS value. The range is from 0 to 7.

You can also mark CoS based on the CoS, DSCP, or IP-precedence
value. You can optionally use a table map to configure CoS. If you do
not enter
table-map table-map-name , the table map default
behavior is copy . See Table Maps, page 583 .
When you complete this step, go to Step 7. on page 641 .
4. cpu traffic qos dscp { dscp_value | cos
[table-map table-map-name ] | dscp
[table-map table-map-name ] | prec
[table-map table-map-name ]}
Mark traffic by setting a new DsCP value or by specifying a table map.

For dscp new-dscp , enter a new DSCP value for the classified traffic.
The range is 0 to 63.

You can also configure a table map to mark DSCP based on the CoS,
DSCP, or IP-precedence value. You can optionally enter the table
name. If you do not enter
table-map table-map-map name, the
table map default behavior is copy . See Table Maps, page 583 .

For additional DSCP classification options, see Classification Based
on IP DSCP, page 578 .
When you complete this step, go to Step 7. on page 641 .
