Displaying Qos Information; Qos Statistics - Cisco ME 3400 Software Configuration Manual

Chapter 33 Configuring QoS
This example shows a policy map with a specified bandwidth and queue size. Traffic that is not DSCP
30 or 10 is assigned a queue limit of 112 packets. Traffic with a DSCP value of 30 is assigned a
queue-limit of 48 packets, and traffic with a DSCP value of 10 is assigned a queue limit of 32 packets.
All traffic not belonging to the class traffic is classified into class-default, which is configured with
10 percent of the total available bandwidth and a large queue size of 256 packets.

Displaying QoS Information

To display QoS information, use one or more of the privileged EXEC commands in
explanations about available keywords, see the command reference for this release.
Table 33-2 Commands for Displaying Standard QoS Information
Command
show class-map [class-map-name]
show policer aggregate [aggregate-policer-name]
show policy-map [policy-map-name | interface
[interface-id] [input | output] [class class-name]]
show cpu traffic qos
show running-config
show table-map [table-map-name]

QoS Statistics

There are several ways to display QoS input and output policy-map statistics.
For input policy maps, you can use the show policy-map interface [interface-id] privileged EXEC
command to display per-class per-policer conform and exceed statistics. Policer conform statistics are
the number of packets that conform to the configured policer profile; policer exceed statistics are the
number of packets that exceed the configured policer profile. The switch does not support per-class
OL-9639-07
Purpose
Display QoS class-map information for all class maps or the
specified class map.
Display information about all aggregate policers or the specified
aggregate policer.
Display QoS policy map information for the specified policy
map name, interface, input or output policy maps, or policy-map
class.
Display the QoS marking values for CPU-generated traffic.
Display the configured class maps, policy maps, table maps, and
aggregate policers.
Display information for all configured table maps or the
specified table map.
