Getting Started Guide
If a valid IP address was not found, the analyzer will still be able to analyze traffic
for statistics, discovering devices and station names. However, without a valid IP
address, the analyzer will not be able to actively discover names. Pressing the
OptiView analyzer button takes you to the Setup | TCP/IP Network
Configuration screen.
- indicates a valid cable. Length is given for twisted-pair copper wires on the
10/100BASE-TX interface.
- indicates that there is a problem with the cable. Other tests depend upon a
functional cable with a successful link. Select this button and view Cable Test
details to diagnose a problem with a cable.
Measurable twisted-pair lengths are from 1 meter to 305 meters
(approximately 3 feet to 1000 feet).
The correct cable type must be selected for Cable Test to report correct
measurements. The cable type is selected on the Cable Test | Twisted-Pair Detail
screen. The default cable type is UTP 100 Ohm Category 5. A misidentified cable
type may cause the measured length to differ from the actual length by up to 15%.

The Cable Test button summarizes the status of the twisted-pair

Note
Switch Statistics displays the nearest switch (including slot, port,
and VLAN ID if available) discovered by examining the bridge
forwarding tables of all the local switches. The progress indicator
(shown in the figure to the left) shows 0/6, which indicates the
discovery process has queried 0 of the 6 known switches on the
network.
When completed, the nearest switch is determined. Also, during
this discovery process, the analyzer is looking for any VLAN
memberships by searching through all the hosts.
Pressing this button takes you directly to the Tools | Interface
Statistics screen for this switch.
The Utilization Statistics button shows network unicast, multicast,
broadcast, collisions, and error percent detail for the connected
network segment. Pressing this button takes you to the Utilization
screen where information is provided in both tabular and graphical
views.
