Quality of Service Debug Commands on Cisco IOS XR Software
Quality of Service Debug Commands on Cisco IOS XR Software
This chapter describes the commands used to debug the quality-of-service (QoS) software system.
debug qos control
To turn on the various quality-of-service (QoS) control-plane debug functions, use the debug qos control command in EXEC mode. To turn off the QoS control-plane debug functions, use the no form of this command.
On the Cisco CRS-1 Router:
debug qos control {hardware}
no debug qos control {hardware}
On the Cisco XR 12000 Series Router:
debug qos control {hardware | plimqos | rm}
no debug qos control {hardware | plimqos | rm}
Syntax Description
hardware
Displays the hardware (EA) events.
plimqos
Displays QoS PLIM events.
rm
Displays the resource manager events.
Defaults
No default behavior or values
Command Modes
EXEC
Command History
Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
Debugging output is assigned high priority in the CPU process and, therefore, can affect system performance. For more information about the impact on system performance when using debug commands, refer to Using Debug Commands on Cisco IOS XR Software.
Task ID
Examples
The following example shows how to enable QoS control-plane classify debug events:
RP/0/RP0/CPU0:router# debug qos control alldebug qos control hardware
To turn on the various quality-of-service (QoS) control hardware debug functions, use the debug qos control hardware command in EXEC mode. To turn off the QoS control hardware debug functions, use the no form of this command.
On the Cisco CRS-1 Router:
debug qos control hardware [classify | cong-avoid | cong-mgmt | error | ha | job | location | mark | misc | police | process | stats]
no debug qos control hardware [classify | cong-avoid | cong-mgmt | error | ha | job | location | mark | misc | police | process | stats]
On the Cisco XR 12000 Series Router:
debug qos control hardware [bwchg | bwchgerr | classify | cong-avoid | cong-mgmt | error | mark | mcast | misc | police | stats] [interface type instance| location node-id]
no debug qos control hardware [bwchg | bwchgerr | classify | cong-avoid | cong-mgmt | error | mark | mcast | misc | police | stats] [interface type instance | location node-id]

Task ID
Examples
The following example shows how to enable the QoS control hardware debug function:
RP/0/RP0/CPU0:router# debug qos control hardwaredebug qos data
To turn on the various quality-of-service (QoS) data plane debug functions, use the debug qos data command in EXEC mode. To turn off the QoS data plane debug functions, use the no form of this command.
On the Cisco CRS-1 Router:
debug qos data {qfifo | txm}
no debug qos data {qfifo | txm}
On the Cisco XR 12000 Series Router:
debug qos data {fifo | txm}
no debug qos data {fifo | txm}

Task ID
Examples
The following example shows how to enable the QoS data plane debug function:
RP/0/RP0/CPU0:router# debug qos data txmdebug snmp mib cbqosmib
To turn on the various quality-of-service (QoS) cbqosmib debug functions, use the debug snmp mib cbqosmib command in EXEC mode. To turn off the QoS qosmib debug functions, use the no form of this command.
debug snmp mib cbqosmib
no debug snmp mib cbqosmib
