The recognized data is transferred as payload of OSI-Layer 2 packets (optionally with VLAN tags). For GOOSE (in '''P'''rotocol '''D'''ata '''U'''nit - PDU) and Sampled Values (in '''A'''pplication '''S'''ervice '''D'''ata '''U'''nit - ASDU) data units, sequence counters are used to allow reordering the received packets and detecting lost packets. | The recognized data is transferred as payload of OSI-Layer 2 packets (optionally with VLAN tags).

For each of the protocols, measures of packets and data (accumulated and as per second rate), provide an impression of the used network capacity. Problems in the packet sequence are available as counters for expected packets (according to seen sequence numbers), lost packets (expected sequence number missing), repeated packets (sequence number seen multiple times). A PCAP download button allows capturing that traffic. | For each of the protocols, measures of packets and data (accumulated and as per second rate), provide an impression of the used network capacity.

All devices sending or receiving IEC 61850 traffic are shown with their MAC address and the detected protocol. Besides packet counts and data rates of the protocol, quality measures like expected, lost and repeated data units/packets are shown. For having a quick overview, multiple graphs can be shown simultaneously for: | All devices sending or receiving IEC 61850 traffic are shown with their MAC address and the detected protocol.

All connections containing IEC 61850 traffic are shown with their two communication partners' MAC address and the detected protocol. Besides packet counts, data rates and time of last detected activity, quality measures like expected, lost and repeated data units/packets are shown.
