13 • Link scheduler configuration
Note Keep in mind that the class local-default comprises all other classes originat-
ing from the SmartNode itself, which are not explicitly stated within the ser-
vice policy profile.
Specifying source classes or lower level source policy profiles
Several commands are available to specify how source classes or lower level source policy profiles have to behave
when transferring packet belonging to them.
Defining fair queuing weight
The command share is used with wfq link arbitration to assign the weight to the selected source class. When
defining a number of source classes, the values are relative to each other. It is recommended to split 100—
which is interpreted as 100%—among all available source classes, e.g. with 20, 30 and 50 as value for the
respective share commands, which represent 20%, 30% and 50%.
This procedure describes defining fair queuing weight
Mode: Source
Command
node (src)[ name ]#share percentage
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 never more), when
overloaded the shaper will behave like a wfq arbiter. Bit-rate specification for shaper (kilobits)
This procedure describes defining the bit-rate
Mode: Source
Command
node (src)[name]#rate [ kilobits |
remaining]
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 con-
trol the amount of "priority" traffic.
Mode: Source
Command
node(src)[ name ]#priority
150
Defines fair queuing weight (relative to other sources) to percent-
age for the selected class or policy name
Defines the (average) bit-rate to the selected in kbps kilobits or as
remaining if a second priority source is getting the unused band-
width for the selected class or policy name
Defines absolute priority effectively bypassing the link arbiter for the
selected class or policy name
