+Config VXLAN Encap outer layers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Configure the outer layer to encapsulate a packet inside a VXLAN tunnel::
+
+ set vxlan ip-version (ipv4|ipv6) vni (vni) udp-src (udp-src) \
+ udp-dst (udp-dst) ip-src (ip-src) ip-dst (ip-dst) eth-src (eth-src) \
+ eth-dst (eth-dst)
+
+ set vxlan-with-vlan ip-version (ipv4|ipv6) vni (vni) udp-src (udp-src) \
+ udp-dst (udp-dst) ip-src (ip-src) ip-dst (ip-dst) vlan-tci (vlan-tci) \
+ eth-src (eth-src) eth-dst (eth-dst)
+
+Those command will set an internal configuration inside testpmd, any following
+flow rule using the action vxlan_encap will use the last configuration set.
+To have a different encapsulation header, one of those commands must be called
+before the flow rule creation.
