Displaying Standard QoS Information

To display standard QoS information, use one or more of the privileged EXEC commands in
Table 29-9 Commands for Displaying Standard QoS Information
Command
show class-map [class-map-name]
show mls qos aggregate-policer
[aggregate-policer-name]
show mls qos interface [interface-id] [buffers | policers |
queueing | statistics]
show mls qos maps [cos-dscp | dscp-cos | dscp-mutation
| ip-prec-dscp | policed-dscp]
show policy-map [policy-map-name [class
class-map-name]
1. 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.

QoS Configuration for the Intelligent Wiring Closet, page 29-71
QoS Configuration for the Distribution Layer, page 29-72
Purpose
Display QoS class maps, which define the match criteria to
classify traffic.
Display the aggregate policer configuration.
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).
Display QoS mapping information. Maps are used to generate an
internal DSCP value, which represents the priority of the traffic.
Display QoS policy maps, which define classification criteria for
incoming traffic.
