4.2 USING LANVIEW
LANVIEW is Cabletron Systems’ built-in visual diagnostic and status
monitoring system. Using LANVIEW, your network troubleshooting
personnel can quickly scan the LANVIEW LEDs to observe network
status or diagnose network problems, and determine which node or
segment is faulty. The definitions and locations for the front panel
LANVIEW LEDs are illustrated in Figure 4-1.
