+How to share a meter between ports in the same switch domain
+------------------------------------------------------------
+
+This section demonstrates how to use the shared meter. A meter M can be created
+on port X and to be shared with a port Y on the same switch domain by the next way:
+
+.. code-block:: console
+
+ flow create X ingress transfer pattern eth / port_id id is Y / end actions meter mtr_id M / end
+
+How to use meter hierarchy
+--------------------------
+
+This section demonstrates how to create and use a meter hierarchy.
+A termination meter M can be the policy green action of another termination meter N.
+The two meters are chained together as a chain. Using meter N in a flow will apply
+both the meters in hierarchy on that flow.
+
+.. code-block:: console
+
+ add port meter policy 0 1 g_actions queue index 0 / end y_actions end r_actions drop / end
+ create port meter 0 M 1 1 yes 0xffff 1 0
+ add port meter policy 0 2 g_actions meter mtr_id M / end y_actions end r_actions drop / end
+ create port meter 0 N 2 2 yes 0xffff 1 0
+ flow create 0 ingress group 1 pattern eth / end actions meter mtr_id N / end
