Class-of-Service Operational Mode Commands

Table 1 summarizes the command-line interface (CLI) commands you can use to monitor and troubleshoot class of service (CoS). Commands are listed in alphabetical order.

Table 1: Class-of-Service (CoS) Operational Mode Commands

Task	Command
Display the entire CoS configuration, including system-chosen defaults.	show class-of-service
(J Series routers only) Display trigger points and associated rates for CoS adaptive shapers.	show class-of-service adaptive-shaper
Display the configuration for the CoS adjustment control profile.	show class-of-service adjustment-control-profile
For each CoS classifier, display the mapping of code point value to forwarding class and loss priority.	show class-of-service classifier
Display the mapping of CoS code point aliases to corresponding bit patterns.	show class-of-service code-point-aliases
Display data points for each CoS random early detection (RED) drop profile.	show class-of-service drop-profile
(M320 routers and T Series routers only) Display the mapping of CoS schedulers to switch fabric traffic priorities and a summary of scheduler parameters for each priority.	show class-of-service fabric scheduler-map
(M320 routers and T Series routers only) Display CoS switch fabric queue statistics.	show class-of-service fabric statistics
Display the mapping of forwarding class names to queue numbers.	show class-of-service forwarding-class
Display entire CoS configuration as it exists in the forwarding table.	show class-of-service forwarding-table
Display the mapping of code point value to queue number and loss priority for each classifier as it exists in the forwarding table.	show class-of-service forwarding-table classifier
For each logical interface, display either the table index of the classifier for a given code point type or the queue number (if it is a fixed classification) in the forwarding table.	show class-of-service forwarding-table classifier mapping
Display the data points of all random early detection (RED) drop profiles as they exist in the forwarding table.	show class-of-service forwarding-table drop-profile
(M320 routers and T Series routers only) Display the scheduler map information as it exists in the forwarding table for switch fabric.	show class-of-service forwarding-table fabric scheduler-map
(J Series routers only) Display the mapping of code point value to loss priority as it exists in the forwarding table.	show class-of-service forwarding-table loss-priority-map
(J Series routers only) For each logical interface, display the loss priority table index.	show class-of-service forwarding-table loss-priority-map mapping
Display mapping of queue number and loss priority to code point value for each rewrite rule as it exists in the forwarding table.	show class-of-service forwarding-table rewrite-rule
For each logical interface, display the table identifier of the rewrite rule map for each code point type.	show class-of-service forwarding-table rewrite-rule mapping
For each physical interface, display the scheduler map information as it exists in the forwarding table.	show class-of-service forwarding-table scheduler-map
For Adaptive Services (AS) PIC link services IQ interfaces (lsq) only, display fragmentation properties for specific forwarding classes.	show class-of-service fragmentation-map
Display the logical and physical interface associations for the classifier, rewrite rules, and scheduler map objects.	show class-of-service interface
Display the configured shaping rate and the quality of service (QoS) adjusted shaping rate for each logical interface set configured for hierarchical class of service (CoS).	show class-of-service interface-set
Display CoS objects associated with an L2TP session.	show class-of-service l2tp-session
(J Series routers only) Display mapping of code point value to loss priority.	show class-of-service loss-priority-map
Display the mapping of the code-point value to the loss priority rewrite rule.	show class-of-service loss-priority-rewrite
Display the classifier type for each class-of-service (CoS) multidestination classifier.	show class-of-service multi-destination
Display the mapping of forwarding classes and loss priority to code point values.	show class-of-service rewrite-rule
(M Series and T Series routers only) Display mapping of CoS objects to routing instances.	show class-of-service routing-instance
Display mapping of schedulers to forwarding classes and a summary of scheduler parameters for each entry.	show class-of-service scheduler-map
(ACX Series Universal Access routers only) Display classifiers configured under system-defaults.	show class-of-service system-defaults
For Gigabit Ethernet IQ and Channelized IQ PICs only, display traffic shaping and scheduling profiles.	show class-of-service traffic-control-profile
