Setup and Configuration
Adding a Traffic Control Class 769
Parameter Description
Value/mask encoding: 0x00/0x1e
default Default: false
One default class per interface must be defined.
TCP ACK Default: false
All TCP ACK packets into this class. This option should be
specified only once per interface.
ToS Value A custom classifier for the given value/mask.
The values are hexadecimal, prefixed by '0x'.
Ex.:
0x56[/0x0F]
6. On the Advanced Traffic Control Classes, configure the following parameter(s) as required:
Parameter Description
interface The interface to which this class applies. Each interface must be
listed only once. Lowercase alphanumerical as well as '.' and '-' characters are allowed.
mark A mark that identifies traffic belonging to this class. This is a
unique integer between 1-255. Each class must have its own unique mark.
Minimum Bandwidth The minimum bandwidth this class should have when the traffic load rises. This can
be either a numeric value or a calculated expression based on the bandwidth of the
interface. A fixed numerical value must only be a number - its unit is specified in Minbw-
unit.
A calculated expression is based on a fraction of the 'full' bandwidth, such as:
. 'full/3' for a third of the bandwidth and
. 'full*9/10' for nine tenths of the bandwidth.
In such a case, do not specify any minbw-unit.
Minimum Bandwidth Units Synopsis: none, kilobits, megabits
Default: none
(per second) Only if the minimum bandwidth is a single numerical value
Maximum Bandwidth The maximum bandwidth this class is allowed to use when the link is idle. This can
be either a numeric value or a calculated expression based on the bandwidth of the
interface. A fixed numerical value must only be a number - its unit is specified in Maxbw-
unit.
A calculated expression is based on a fraction of the 'full' bandwidth, such as:
. 'full/3' for a third of the bandwidth and
. 'full*9/10' for nine tenths of the bandwidth.
In such a case, do not specify any maxbw-unit.
Maximum Bandwidth Units Synopsis: none, kilobits, megabits
Default: none
(per second) only if max-bandwidth is a single numerical value
priority Default: 0
The priority in which classes will be serviced. Higher priority
classes will experience less delay since they are serviced
first. Priority values are serviced in ascending order
(e.g. 0 is higher priority than 1. Minimum: 7).
