+Telemetry Mode
+--------------
+
+The telemetry mode support for ``l3fwd-power`` is a standalone mode, in this mode
+``l3fwd-power`` does simple l3fwding along with calculating empty polls, full polls,
+and busy percentage for each forwarding core. The aggregation of these
+values of all cores is reported as application level telemetry to metric
+library for every 500ms from the main core.
+
+The busy percentage is calculated by recording the poll_count
+and when the count reaches a defined value the total
+cycles it took is measured and compared with minimum and maximum
+reference cycles and accordingly busy rate is set to either 0% or
+50% or 100%.

+.. code-block:: console
+
+ ./<build_dir>/examples/dpdk-l3fwd-power --telemetry -l 1-3 -- -p 0x0f --config="(0,0,2),(0,1,3)" --telemetry
+
+The new stats ``empty_poll`` , ``full_poll`` and ``busy_percent`` can be viewed by running the script
+``/usertools/dpdk-telemetry-client.py`` and selecting the menu option ``Send for global Metrics``.
+
+PMD power management Mode
+-------------------------
+
+The PMD power management mode support for ``l3fwd-power`` is a standalone mode.
+In this mode, ``l3fwd-power`` does simple l3fwding
+along with enabling the power saving scheme on specific port/queue/lcore.
+Main purpose for this mode is to demonstrate
+how to use the PMD power management API.
+
+.. code-block:: console
+
+ ./build/examples/dpdk-l3fwd-power -l 1-3 -- --pmd-mgmt -p 0x0f --config="(0,0,2),(0,1,3)"
+
+PMD Power Management Mode
+-------------------------
+
+There is also a traffic-aware operating mode that,
+instead of using explicit power management,
+will use automatic PMD power management.
+This mode is limited to one queue per core,
+and has three available power management schemes:
+
+``monitor``
+ This will use ``rte_power_monitor()`` function to enter
+ a power-optimized state (subject to platform support).
+
+``pause``
+ This will use ``rte_power_pause()`` or ``rte_pause()``
+ to avoid busy looping when there is no traffic.
+
+``scale``
+ This will use frequency scaling routines
+ available in the ``librte_power`` library.
+
+See :doc:`Power Management<../prog_guide/power_man>` chapter
+in the DPDK Programmer's Guide for more details on PMD power management.
