Configuring QoS
Displaying Standard QoS Information
To display standard QoS information, use one or more of the privileged EXEC commands in
Table 30-9 Commands for Displaying QoS Information
Command
show class-map [class-map-name]
show policy-map [policy-map-name [class class-name]]
show mls qos maps [cos-dscp | dscp-cos]
show mls qos interface [interface-id] [policers]
show mls masks [qos | security]
show wrr-queue cos-map
show wrr-queue bandwidth
1. Available only on a switch running the EI.
2. Access control parameters are called masks in the switch CLI commands and output.
Standard QoS Configuration Examples
These examples are applicable only if your switch is running the EI.

Purpose
Display QoS class maps, which define the match criteria to
classify traffic.
1
Display QoS policy maps, which define classification criteria for
incoming traffic.
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
statistics.
Display details regarding the masks
ACLs.
Display the mapping of the CoS priority queues.
Display the WRR bandwidth allocation for the CoS priority
queues.
