5.1.3. Network Counts
The Network layer statistics panel has similar purpose than the Frame layer statistics
but in this case it displays counters related with the IP layer rather than with Ethernet.
Network statistics are not available in Ethernet Endpoint mode because the IP structure
is neither generated nor decoded in this operation mode.
UDP errors Displays information about the total number of errored UDP
packets.
UDP packets are considered to contain errors if either their
structure or their content is invalid. For UDP, this means that
the packet has an unexpected length or it contains checksum
errors.
TCP errors Displays information about the total number of errored TCP
packets.
TCP packets are considered to contain errors if either their
structure or their content is invalid. For TCP, this means that
the packet contains checksum errors.

Metric Description
IPv4 / IPv6 TX Aggregated number of transmitted IPv4 and IPv6 packets
since the last test start.
IPv4 packets are encapsulated in Ethernet frames carrying
the 0x0800 Type. IPv6 packets are encapsulated with the
Ethertype field set to 0x86dd.
IPv4 RX Total number of received IPv4 packets since the last test
start.
IPv4 packets are encapsulated in Ethernet frames carrying
the 0x0800 Type.
IPv4 frags Counter that increases every time a fragment corresponding
to an IPv4 fragmented packet is received. A fragment is
detected because the More Fragments (MF) flag is enabled
in the frame.
