QoS Configuration Examples
This section provides a QoS migration path to help you quickly implement QoS features based on your
existing network and planned changes to your network, as shown in
Figure 20-10
. It contains this
information:
•
QoS Configuration for the Common Wiring Closet, page 20-57

Table 20-6 Commands for Displaying QoS Information
Command
Purpose
show class-map [class-map-name]
Display QoS class maps, which define the match criteria to
classify traffic.
show policy-map [policy-map-name [class class-name] |
[interface interface-id]
Display QoS policy maps, which define classification criteria for
incoming traffic.
show mls qos aggregate-policer
[aggregate-policer-name]
Display the aggregate policer configuration.
show mls qos maps [cos-dscp | dscp-cos | dscp-mutation
| ip-prec-dscp | policed-dscp]
Display QoS mapping information. Maps are used to generate an
internal DSCP value, which represents the priority of the traffic.
show mls qos interface [interface-id] [buffers | policers |
queueing | statistics]
Display QoS information at the interface level, including the
configuration of the egress queues and the CoS-to-egress-queue
map, which interfaces have configured policers, and ingress and
egress statistics (including the number of bytes dropped).

You can define up to 16 DSCP values for which byte or packet statistics are gathered by hardware by using the mls qos monitor {bytes | dscp dscp1 ...
dscp8 | packets} interface configuration command and the show mls qos interface statistics privileged EXEC command.
