TC COMMANDS
The following commands are available for qdiscs, classes and
filter:
add Add a qdisc, class or filter to a node. For all entities,
a parent must be passed, either by passing its ID or by
attaching directly to the root of a device. When creating
a qdisc or a filter, it can be named with the handle
parameter. A class is named with the classid parameter.
delete A qdisc can be deleted by specifying its handle, which may
also be 'root'. All subclasses and their leaf qdiscs are
automatically deleted, as well as any filters attached to
them.
change Some entities can be modified 'in place'. Shares the
syntax of 'add', with the exception that the handle cannot
be changed and neither can the parent. In other words,
change cannot move a node.
replace
Performs a nearly atomic remove/add on an existing node
id. If the node does not exist yet it is created.
get Displays a single filter given the interface DEV, qdisc-
id, priority, protocol and filter-id.
show Displays all filters attached to the given interface. A
valid parent ID must be passed.
link Only available for qdiscs and performs a replace where the
node must exist already.
