+Preparing test run of vEPC test case
+------------------------------------
+
+Provided vEPC test cases are examples of emulation of vEPC infrastructure
+components, such as UE, eNodeB, MME, SGW, PGW.
+
+Location of vEPC test cases: ``samples/vnf_samples/nsut/vepc/``.
+
+Before running a specific vEPC test case using NSB, some preconfiguration
+needs to be done.
+
+Update Spirent Landslide TG configuration in pod file
+=====================================================
+
+Examples of ``pod.yaml`` files could be found in
+:file:`etc/yardstick/nodes/standalone`.
+The name of related pod file could be checked in the context section of NSB
+test case.
+
+The ``pod.yaml`` related to vEPC test case uses some sub-structures that hold the
+details of accessing the Spirent Landslide traffic generator.
+These subsections and the changes to be done in provided example pod file are
+described below.
+
+1. ``tas_manager``: data under this key holds the information required to
+access Landslide TAS (Test Administration Server) and perform needed
+configurations on it.
+
+ * ``ip``: IP address of TAS Manager node; should be updated according to test
+   setup used
+ * ``super_user``: superuser name; could be retrieved from Landslide documentation
+ * ``super_user_password``: superuser password; could be retrieved from
+   Landslide documentation
+ * ``cfguser_password``: password of predefined user named 'cfguser'; default
+   password could be retrieved from Landslide documentation
+ * ``test_user``: username to be used during test run as a Landslide library
+   name; to be defined by test run operator
+ * ``test_user_password``: password of test user; to be defined by test run
+   operator
+ * ``proto``: *http* or *https*; to be defined by test run operator
+ * ``license``: Landslide license number installed on TAS
+
+2. The ``config`` section holds information about test servers (TSs) and
+systems under test (SUTs). Data is represented as a list of entries.
+Each such entry contains:
+
+ * ``test_server``: this subsection represents data related to test server
+   configuration, such as:
+
+   * ``name``: test server name; unique custom name to be defined by test
+     operator
+   * ``role``: this value is used as a key to bind specific Test Server and
+     TestCase; should be set to one of test types supported by TAS license
+   * ``ip``: Test Server IP address
+   * ``thread_model``: parameter related to Test Server performance mode.
+     The value should be one of the following: "Legacy" | "Max" | "Fireball".
+     Refer to Landslide documentation for details.
+   * ``phySubnets``: a structure used to specify IP ranges reservations on
+     specific network interfaces of related Test Server. Structure fields are:
+
+    * ``base``: start of IP address range
+    * ``mask``: IP range mask in CIDR format
+    * ``name``: network interface name, e.g. *eth1*
+    * ``numIps``: size of IP address range
+
+ * ``preResolvedArpAddress``: a structure used to specify the range of IP
+   addresses for which the ARP responses will be emulated
+
+    * ``StartingAddress``: IP address specifying the start of IP address range
+    * ``NumNodes``: size of the IP address range
+
+ * ``suts``: a structure that contains definitions of each specific SUT
+   (represents a vEPC component). SUT structure contains following key/value
+   pairs:
+
+    * ``name``: unique custom string specifying SUT name
+    * ``role``: string value corresponding with an SUT role specified in the
+      session profile (test session template) file
+    * ``managementIp``: SUT management IP adress
+    * ``phy``: network interface name, e.g. *eth1*
+    * ``ip``: vEPC component IP address used in test case topology
+    * ``nextHop``: next hop IP address, to allow for vEPC inter-node communication
+
+Update NSB test case definitions
+================================
+NSB test case file designated for vEPC testing contains an example of specific
+test scenario configuration.
+Test operator may change these definitions as required for the use case that
+requires testing.
+Specifically, following subsections of the vEPC test case (section **scenarios**)
+may be changed.
+
+1. Subsection ``options``: contains custom parameters used for vEPC testing
+
+ * subsection ``dmf``: may contain one or more parameters specified in
+   ``traffic_profile`` template file
+ * subsection ``test_cases``: contains re-definitions of parameters specified
+   in ``session_profile`` template file
+
+    .. note:: All parameters in ``session_profile``, value of which is a
+      placeholder, needs to be re-defined to construct a valid test session.
+
+2. Subsection ``runner``: specifies the test duration and the interval of
+TG and VNF side KPIs polling. For more details, refer to :doc:`03-architecture`.
