+
+.SH DESCRIPTION
+
+The
+.B actions
+object in
+.B tc
+allows a user to define actions independently of a classifier (filter). These
+actions can then be assigned to one or more filters, with any
+packets matching the classifier's criteria having that action performed
+on them.
+
+Each action type (mirred, police, etc.) will have its own table to store
+all created actions.
+
+.SH OPERATIONS
+.TP
+.B add
+Create a new action in that action's table.
+
+.TP
+.B change
+.TQ
+.B replace
+Make modifications to an existing action.
+.TP
+.B get
+Display the action with the specified index value. When combined with the
+.B -s
+option for
+.BR tc ","
+display the statistics for that action.
+.TP
+.B delete
+Delete the action with the specified index value. If the action is already
+associated with a classifier, it does not delete the classifier.
+.TP
+.B ls
+.TQ
+.B list
+List all the actions in the specified table. When combined with the
+.B -s
+option for
+.BR tc ","
+display the statistics for all actions in the specified table.
+.TP
+.B flush
+Delete all actions stored in the specified table.
+
+.SH ACTION OPTIONS
+Note that these options are available to all action types.
+.TP
+.BI index " INDEX"
+Specify the table index value of an action.
+.I INDEX
+is a 32-bit value that is unique to the specific type of action referenced.
+
+.RS
+For
+.BR add ", " change ", and"
+.B replace
+operations, the index is
+.BR optional.
+When adding a new action,
+specifying an index value will assign the action to that index unless that
+index value has already been assigned. Omitting the index value for an add
+operation will cause the kernel to assign a value to the new action.
+.RE
+
+.RS
+For
+.BR get " and " delete
+operations, the index is
+.B required
+to identify the specific action to be displayed or deleted.
+.RE
+
+.TP
+.BI cookie " COOKIE"
+In addition to the specific action, mark the matching packet with the value
+specified by
+.IR COOKIE "."
+The
+.I COOKIE
+is a 128-bit value that will not be interpreted by the kernel whatsoever.
+As such, it can be used as a correlating value for maintaining user state.
+The value to be stored is completely arbitrary and does not require a specific
+format. It is stored inside the action structure itself.
+
+.TP
+.I CONTROL
+The
+.I CONTROL
+indicates how
+.B tc
+should proceed after executing the action. Any of the following are valid:
+.RS
+.TP
+.B reclassify
+Restart the classifiction by jumping back to the first filter attached to
+the action's parent.
+.TP
+.B pipe
+Continue with the next action. This is the default control.
+.TP
+.B drop
+Drop the packed without running any further actions.
+.TP
+.B continue
+Continue the classification with the next filter.
+.TP
+.B pass
+Return to the calling qdisc for packet processing, and end classification of
+this packet.
