All Cisco-Network Study Notes: Class-Based Shaping Command Reference-FRTS Command Reference-

This area lists added capacity and facts to annular out the advantage of the capacity in this chapter.

Unlike best of the Cisco Press Assay Certification Guides, this “Foundation Summary” does not

repeat advice presented in the “Foundation Topics” area of the chapter. Please booty the

time to apprehend and abstraction the capacity in the “Foundation Topics” area of the chapter, as able-bodied as

review items acclaimed with a Key Topic icon.

Table 14-9 lists commands accompanying to CB Shaping.

Table 14-10 lists commands accompanying to FRTS.

Table 14-9 Class-Based Abstraction Command Reference

Command Mode and Function

shape [average | peak] mean-rate [[burst-size]

[excess-burst-size]]

Class agreement mode; enables abstraction for the

class

shape [average | peak] percent percent

[[burst- size] [excess-burst-size]]

Enables abstraction based on allotment of

bandwidth

shape adaptive min-rate Enables the minimum amount for adaptive shaping

shape fecn-adapt Causes absorption of BECN $.25 afterwards cancellation of an

FECN

service-policy {input | output}

policy- map-name

Interface or subinterface agreement mode;

enables CB Abstraction on the interface

shape max-buffers number-of-buffers Sets the best chain breadth for the default

FIFO abstraction queue

show policy-map policy-map-name Lists agreement advice about all MQCbased

QoS tools

show policy-map interface-spec

[input | output] [class class-name]

Lists statistical advice about the behavior of

all MQC-based QoS tools

Table 14-10 FRTS Command Reference

Command Mode and Function

frame-relay traffic-shaping Interface subcommand; enables FRTS on the interface

class name Acclimated beneath the interface-dlci to point to a map class

frame-relay chic name Acclimated beneath an interface or subinterface to point to a map

class

map-class frame-relay map-class-name Global command to name map class, with subcommands

detailing a set of abstraction parameters

service-policy achievement policy-map-name Acclimated in a map chic to accredit LLQ or CBWFQ

frame-relay traffic-rate boilerplate [peak] Acclimated in a map chic to ascertain abstraction rates

frame-relay bc out $.25 Acclimated in a map chic to absolutely set Bc

frame-relay be out $.25 Acclimated in a map chic to absolutely set Be

frame-relay cir out bps Acclimated in a map chic to absolutely set CIR

frame-relay adaptive-shaping {becn |

foresight}

Used in a map chic to both accredit adaptive abstraction and

define what causes FRTS to apathetic down

frame-relay mincir out bps Acclimated in a map chic to ascertain how far adaptive shaping

will lower the rate

frame-relay tc milliseconds Acclimated in a map chic to absolutely set Tc

frame-relay qos-autosense Interface command cogent the router to use ELMI to

discover the CIR, Bc, and Be from the switch

shape adaptive mean-rate-lower-bound Policy-map agreement command acclimated to appraisal the

available bandwidth application BECN messages; shapes

traffic to no beneath than the configured mean-rate-lowerbound

parameter

shape fecn-adapt Policy-map agreement command that reflects FECN

messages as BECN letters to the Frame Relay switch

show frame-relay pvc [interface interface]

[dlci]

Shows PVC statistics, including abstraction statistics

show traffic-shape [interface-type

interface-number]

Shows advice about FRTS agreement per VC

show traffic-shape chain [interfacenumber

[dlci dlci-number]]

Shows advice about the queuing apparatus acclimated with the

shaping queue

show traffic-shape statistics [interfacetype

interface-number]

Shows traffic-shaping statistics

Memory Builders 503

Table 14-11 provides a command advertence for CB Policing.

Memory Builders

The CCIE Routing and Switching accounting exam, like all Cisco CCIE accounting exams, covers a fairly

broad set of topics. This area provides some basal accoutrement to advice you exercise your anamnesis about

some of the broader capacity covered in this chapter.

Fill in Key Tables from Memory

Appendix E, “Key Tables for CCIE Study,” on the CD in the aback of this book contains abandoned sets

of some of the key arbitrary tables in anniversary chapter. Print Appendix E, accredit to this chapter’s tables

in it, and ample in the tables from memory. Accredit to Appendix F, “Solutions for Key Tables for CCIE

Study,” on the CD to analysis your answers.
