+#. **Graph Title**: describes tested VPP packet path. Format:
+
+ - wire encapsulation ``dot1qip4vlxan``,
+ - VPP forwarding mode ``l2bd``,
+ - total number {Y} of service chains ``{Y}ch``,
+ - total number of chains being reconfigured ``1ach``,
+ - total number of vhost-user interfaces forwarding packets on VPP with {Y}
+ chains and {X} VMs per chain ``{2XY}vh`` (2 interfaces per {X} VMs per {Y}
+ chains),
+ total number {XY} of VNF VMs forwarding packets ``{XY}vm`` and finally
+ - VNF workload in VM ``testpmd``.
