The corresponding ``step`` is used for ranging the IP addresses from the `ip_addrs``, ``tg_gateway_ip_addrs`` and ``gateway_ip_addrs`` base addresses.
0.0.0.1 is the default step for all IP ranges. In ``ip_addrs``, 'random' can be configured which tells NFVBench to generate random src/dst IP pairs in the traffic stream.
+UDP ports can be controlled with the following NFVbench configuration options:
+
+.. code-block:: bash
+
+ udp_src_port: ['1024', '65000']
+ udp_dst_port: 53
+ udp_port_step: 1
+
+``udp_src_port`` and ``udp_dst_port`` are the UDP port value used by the traffic generators.
+These can be written for unique port or range ports for all flow.
+
+The corresponding ``udp_port_step`` is used for ranging the UDP port.
+1 is the default step for all UDP ranges, 'random' can be configured which tells NFVBench to generate random src/dst UDP pairs in the traffic stream.
+
+NB:
+ Use of UDP range will increase possible values of flows (based on ip src/dst and port src/dst tuple).
+ NFVBench will calculate the least common multiple for this tuple to adapt flows generation to ``flow_count`` parameter.

Traffic Configuration via CLI
-----------------------------
NFVbench will dicover the MAC addresses to use for generated frames using:
- either OpenStack discovery (find the MAC of an existing VM) in the case of PVP and PVVP service chains
- or using dynamic ARP discovery (find MAC from IP) in the case of external chains.
+- In case of L3 chain with SDN-GW or router between traffic generator and loop VM ARP is needed to discover SDN-GW mac addresses, use ``--loop-vm-arp`` flag or ``loop_vm_arp: true`` in config file.
