Chapter 37 Configuring QoS
Displaying Standard QoS Information
To return to the default setting, use the no srr-queue bandwidth limit interface configuration command.
This example shows how to limit the bandwidth on a port to 80 percent:
Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# srr-queue bandwidth limit 80
When you configure this command to 80 percent, the port is idle 20 percent of the time. The line rate
drops to 80 percent of the connected speed, which is 800 Mb/s. These values are not exact because the
hardware adjusts the line rate in increments of six.
Displaying Standard QoS Information
The commands listed in Table 37-15 apply to both IPv4 and IPv6 traffic when a dual-ipv4-and-ipv6
SDM templates is configured.
Step 5 show mls qos interface [ interface-id ]
queueing
Verify your entries.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Table 37-15 Commands for Displaying Standard QoS Information
Command Purpose
show class-map [ class-map-name ] Display QoS class maps, which define the match criteria to
classify traffic.
show mls qos Display global QoS configuration information.
show mls qos aggregate-policer
[ aggregate-policer-name ]
Display the aggregate policer configuration.
show mls qos input-queue Display QoS settings for the ingress queues.
show mls qos interface [ interface-id ] [ buffers | policers |
queueing | statistics ]
Display QoS information at the port level, including the buffer
allocation, which ports have configured policers, the queueing
strategy, and the ingress and egress statistics.
show mls qos maps [ cos-dscp | cos-input-q |
cos-output-q | dscp-cos | dscp-input-q | dscp-mutation
dscp-mutation-name | dscp-output-q | ip-prec-dscp |
policed-dscp ]
Display QoS mapping information.
show mls qos queue-set [ qset-id ] Display QoS settings for the egress queues.
show mls qos vlan vlan-id Display the policy maps attached to the specified SVI.
show policy-map [ policy-map-name [ class
class-map-name ]]
Display QoS policy maps, which define classification criteria for
incoming traffic.
Note
Do not use the show policy-map interface privileged
EXEC command to display classification information
for incoming traffic. The
control-plane and interface
keywords are not supported, and the statistics shown in
the display should be ignored.
show running-config | include rewrite Display the DSCP transparency setting.
