Switch Status
The graph only scales to 40% utilization. Network utilization above this level
indicates serious performance problems.
The graph also shows you if a port is active, disabled, or not connected.
Alert Log Area - Find/Fix/Inform
The “Find/Fix/Inform” capability of a device helps you proactively manage
your network by displaying network traps and problem conditions in one
easily accessible browser page. The device itself monitors counters, internal
hardware information, and network traffic. When a problem is discovered,
such as loss of link, a problem cable, or a broadcast storm, the Alert Log
displays clear messages about the problem. When you double-click on an
alert in the Alert Log (or select the alert and click on the Open Event button),
the Alerts page displays more information about the alert as well as some
suggestions for fixing the problem.
For example, the Alert Log may display the alert “Cable Length”. The
following information is available:
Description:
Packet loss detected on port 4. This may be due to an overextended LAN
topology or faulty hardware. The loss was detected on this port, but the
actual problem can be occurring elsewhere on this segment.
Solution:
■ Verify the network topology is within IEEE 802.3 topology standards. All
ThinLan coaxial cabling must be 185 meters or shorter. No more than 4
repeaters are allowed between any two stations in the network.
■ Insert bridges or switches between repeaters to extend network topology
if needed.
■ Also, check for faulty cabling, transceivers, and NICs.
Using the Find/Fix/Inform capability, the device can isolate a problem that
occurs on one port, preventing it from affecting the entire network.
See Alerts - Find/Fix/Inform
for information on reading and acknowledging
alerts.
Status - Port Counters
The Port Counters information for switches displays specific network
conditions or traffic. See the online help for more information about each
counter.
