Displaying QoS Information

Displaying QoS Information
To display the current QoS information, use one or more of the privileged EXEC commands in
Table
Table 20-6 Commands for Displaying QoS Information
Command
show class-map [class-map-name]
show policy-map [policy-map-name [class class-name] |
[interface interface-id]
show mls qos aggregate-policer
[aggregate-policer-name]
show mls qos maps [cos-dscp | dscp-cos | dscp-mutation
| ip-prec-dscp | policed-dscp]
show mls qos interface [interface-id] [buffers | policers |
queueing | statistics]
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.

Purpose
Display QoS class maps, which define the match criteria to
classify traffic.
Display QoS policy maps, which define classification criteria for
incoming traffic.
Display the aggregate policer configuration.
Display QoS mapping information. Maps are used to generate an
internal DSCP value, which represents the priority of the traffic.
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).
