Output Fields

Table 1 describes the output fields for the show class-of-service scheduler-map command. Output fields are listed in the approximate order in which they appear.

Table 1: show class-of-service scheduler-map Output Fields

Field Name

Field Description

Scheduler map

Name of the scheduler map.

(Enhanced subscriber management for MX Series routers) The name of the dynamic scheduler map object is associated with a generated UID (for example, SMAP-1_UID1002) instead of with a subscriber interface.

Index

Index of the indicated object. Objects having indexes in this output include scheduler maps, schedulers, and drop profiles.

(Enhanced subscriber management for MX Series routers) Index values for dynamic CoS traffic control profiles are larger for enhanced subscriber management than they are for legacy subscriber management.

Scheduler

Name of the scheduler.

Forwarding class

Classification of a packet affecting the forwarding, scheduling, and marking policies applied as the packet transits the router.

Transmit rate

Configured transmit rate of the scheduler (in bps). The rate is a percentage of the total interface bandwidth, or the keyword remainder, which indicates that the scheduler receives the remaining bandwidth of the interface.

Rate Limit

Rate limiting configuration of the queue. Possible values are none, meaning no rate limiting, and exact, meaning the queue only transmits at the configured rate.

Maximum buffer delay

Amount of transmit delay (in milliseconds) or the buffer size of the queue. The buffer size is shown as a percentage of the total interface buffer allocation, or by the keyword remainder to indicate that the buffer is sized according to what remains after other scheduler buffer allocations.

Priority

Scheduling priority: low or high.

Excess priority

Priority of excess bandwidth: low, medium-low, medium-high, high, or none.

Explicit Congestion Notification

(QFX Series, OCX Series, and EX4600 switches only) Explicit congestion notification (ECN) state:

  • Disable—ECN is disabled on the specified scheduler

  • Enable—ECN is enabled on the specified scheduler

ECN is disabled by default.

Adjust minimum

Minimum shaping rate for an adjusted queue, in bps.

Adjust percent

Bandwidth adjustment applied to a queue, in percent.

Drop profiles

Table displaying the assignment of drop profiles by name and index to a given loss priority and protocol pair.

Loss priority

Packet loss priority for drop profile assignment.

Protocol

Transport protocol for drop profile assignment.

Name

Name of the drop profile.

Sample Output

show class-of-service scheduler-map

show class-of-service scheduler-map (QFX Series)

Release Information

Command introduced before Junos OS Release 7.4.
