About QoS Statistics
You can display various QoS statistics for the device. By default, statistics are enabled, but you can disable this feature. For more information, see the Configuration Examples For Monitoring QoS Statistics section.
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
You can display various QoS statistics for the device. By default, statistics are enabled, but you can disable this feature. For more information, see the Configuration Examples For Monitoring QoS Statistics section.
Monitoring QoS statistics has the following prerequisites:
You must be familiar with using modular QoS CLI.
You are logged on to the device.
Monitoring QoS statistics has the following guidelines and limitations:
show commands with the internal keyword are not supported.
The show queuing interface command can display information about internal interfaces.
The command format for this information is specified as ii x/y/z . Where x is the module number, y is the value 1, and z is the internal interface number within the module.
Note |
The number of internal interfaces within a module varies based on the type of the line card. |
Note |
Alternatively, you can display information about internal interfaces by providing the module number in the show queuing command. By including the module number, queuing information for both front-panel and internal interfaces of the module are displayed together. |
Example:
switch# show queuing interface ii 4/1/2
slot 4

Egress Queuing for ii4/1/2 [System]

You can enable or disable QoS statistics for all interfaces on the device. By default, QoS statistics are enabled.
Enable QoS statistics:
qos statistics
Disable QoS statistics:
no qos statistics
Command or Action | Purpose | |
---|---|---|
Step 1 |
configure terminal Example:
|
Enters global configuration mode. |
Step 2 |
Enable or disable QoS statistics:
Example:
|
|
Step 3 |
show policy-map interface Example:
|
(Optional) Displays the statistics status and the configured policy maps on all interfaces. |
Step 4 |
copy running-config startup-config Example:
|
(Optional) Saves the running configuration to the startup configuration. |
You can display QoS statistics for all interfaces or a selected interface, data direction, or a QoS type.
Command or Action | Purpose |
---|---|
show policy-map [policy-map-name] [interface [input | output]] [type {control-plane | network-qos | qos | queuing}] Example:
|
Displays statistics and the configured policy maps on all interfaces, the specified interface, or on a specified data direction or QoS type. |
You can clear QoS statistics for all interfaces or a selected interface, data direction, or QoS type.
Command or Action | Purpose |
---|---|
clear qos statistics [interface [input | output] [type {qos | queuing}]] Example:
|
Clears statistics and the configured policy maps on all interfaces or the specified interface or on a specified data direction or QoS type. |
The following example shows how to display the QoS statistics:
Global statistics status : enabled
Ethernet6/1
Service-policy (queuing) output: default-out-policy
Class-map (queuing): c-out-q3 (match-any)
priority level 1
Class-map (queuing): c-out-q2 (match-any)
bandwidth remaining percent 0
Class-map (queuing): c-out-q1 (match-any)
bandwidth remaining percent 0
Class-map (queuing): c-out-q-default (match-any)
bandwidth remaining percent 100
The following example shows how to obtain information about queuing and PFC related counters:
switch(config-vlan-config)# show queuing interface ethernet 2/1
Egress Queuing for Ethernet2/1 [System]
