Table 1: Class of Service Information and the Corresponding CLI show Commands
Information Displayed | Corresponding CLI Command |
|---|---|
| Interfaces | |
Information about the physical and logical interfaces in the system and details about the CoS components assigned to these interfaces. | show class-of-service interface |
| Classifiers | |
Forwarding classes and loss priorities that incoming packets are assigned to based on the packet's CoS values. | show class-of-service classifier |
| CoS Value Aliases | |
CoS value aliases that the system is using to represent DiffServ code point (DSCP), DSCP IPv6, MPLS experimental (EXP), and IPv4 precedence bits. | show class-of-service code-point-aliases |
| RED Drop Profiles | |
Detailed information about the drop profiles used by the system. Also, displays a graph of the random early detection (RED) curve that the system uses to determine the queue fullness and drop probability. | show class-of-service drop-profile |
| Forwarding Classes | |
Assignment of forwarding classes to queue numbers. | show class-of-service forwarding-class |
| Rewrite Rules | |
Packet CoS value rewrite rules based on the forwarding classes and loss priorities. | show class-of-service rewrite-rule |
| Scheduler Maps | |
Assignment of forwarding classes to schedulers. Schedulers include transmit rate, rate limit, and buffer size. | show class-of-service scheduler-map |
