Physical layer
At the Physical layer, AthTek NetWalk provides statistics describing the actual transmission of network data, including counts for various packet and error types (such as broadcasts, multicasts, and CRC errors). Counts are provided both globally and for each individual detected MAC address. In addition, AthTek NetWalk tracks VLANs at the Physical layer.
