The Inline Mode allows users to non-intrusively monitor network traffic (10/100/1000BaseTX) to identify protocols, port usage, VoIP statistics and network utilization. The LANEXPERT can capture and store up to 10,000 packets with user defined filters for detailed analysis in the field or downloaded over the network or to a USB flash drive. Using either RJ-45 port, tests including Ping, Link, Trace Route, DHCP and Discovery are used to quickly identify network problems The LANEXPERT can generate up to 100% traffic loading with control of packet rate and size to demonstrate network performance at various traffic levels. Additionally, a stress test that generates traffic and measures performance metrics, in accordance with RFC 2544, is also provided. The stress test can be conducted using the two independent ports on a single unit or used with a second unit located remotely on a network. PoE tests include voltage and inline current measurement to determine the actual power used by a powered device. The LANEXPERT also test cables for shorts, opens, split pairs, reversed pairs, measures cable length and generates tones for cable tracing. The LANEXPERT is a comprehensive network analyzer that allows users to deliver robust and reliable network services with a single test device. LAN installers, technicians, managers and service providers can now get expert network help at an affordable price.
