Classes

The syntax for creating a class is shown below:

tc class [ add | del | change | get ] dev STRING
       [ classid CLASSID ] [ root | parent CLASSID ]
       [ [ QDISC_KIND ] [ help | OPTIONS ] ]

       tc class show [ dev STRING ] [ root | parent CLASSID ]
Where:
QDISC_KIND := { prio | cbq | etc. }

The QDISC_KIND can be one of the queuing disciplines that support classes. The interpretation of the fields:

• classid represents the handle that is assigned to the class by the user. It consists of a major number and a minor number, which have been discussed already.
• root indicates that the class represents the root class in the link sharing hierarchy.
• parent indicates the handle of the parent of the queuing discipline.
