-| ... | Test suite uses 2-node topology TG - DUT1 - TG with two links
-| ... | between nodes as well as 3-node topology TG - DUT1 - DUT2 - TG
-| ... | with one link between nodes. Test packets are sent in both directions
-| ... | and contain Ethernet header, IPv4 header and ICMP message. Ethernet
-| ... | header MAC addresses are matching MAC addresses of the TG node.

+| ... | to all links.
+| ... | *(Cfg) DUT configuration:* DUT1 and DUT2 are configured with L2

+| ... | learning enabled and Split Horizon Groups (SHG) depending on
+| ... | test case.
+| ... | *(Ver) TG verification:* Test ICMPv4 (or ICMPv6) Echo Request packets
