Command

Purpose

 

 

node(src)[name]#share percentage

Defines fair queuing weight (relative to other sources) to percent-

 

age for the selected class or policy name

 

 

Defining the bit-rate

The command rate is used with shaper link arbitration to assign the (average) bit-rate to the selected source. When enough bandwidth is available each source will exactly receive this bandwidth (but no more), when overloaded the shaper will behave like a wfq arbiter. Bit-rate specification for shaper (kilobits).

Purpose

 

 

node(src)[name]#rate [kilobits

Defines the (average) bit-rate to the selected in kbps kilobits or as

remaining]

remaining if a second priority source is getting the unused band-

 

width for the selected class or policy name

 

 

Defining absolute priority

This command priority can only be applied to classes, but not to lower level polices. The class is given absolute priority effectively bypassing the link arbiter. Care should be taken, as traffic of this class may block all other traffic. The packets given “priority” are taken into account by the “rate-limit”. Use the command police to control the amount of “priority” traffic.

Purpose

 

 

node(src)[name]#priority

Defines absolute priority effectively bypassing the link arbiter for the

 

selected class or policy name

 

 

Defining the maximum queue length

The command queue-limitspecifies the maximum number of packets queued for the class name. Excess pack- ets are dropped. Used in “class” mode—queuing only happens at the leaf of the arbitration hierarchy tree. The no form of this command reverts the queue-limit to the internal default value, which depends on

your configuration.

node(src)[name]#queue-limit

Defines the maximum number of packets queued for the selected class

or policy name

 

 

Specifying the type-of-service (TOS) field

The set ip tos command specifies the type-of-service (TOS) field value applied to packets of the class name. TOS and DSCP markings cannot be used at the same time. The no form of this command disables TOS marking.
