Observing Collision Level
When "COLLISION" is the menu item in the Message Zone, the Port
Number will flash for each port that is connected and the Bar Gauge will
indicate the percentage of collision for these ports. Collision occurs when
two or more ports send data to the same port at approximately the same time.
The Collision percent can be calculated with the following formula.
Collision Ratio = (number of packets collided / number of packets
transmitted) * 100.
Monitoring Ports Status
The status of each port can be viewed by selecting Ports Status from the
Main Menu. Ports 1~24 can be running in Full Duplex or Half Duplex.
Furthermore, Ports 25, 26 and 27 can be running at different speeds, say 10M
or 100Mbps. It is useful to check the port setting to see if it has been running
in the right mode. When the ports are running in Auto Negotiation Mode, it is
easier to manage them.
Note: If it is difficult to connect to a remote device, the first thing to
check is that both sides are running at the same mode.
You can watch the status of all the ports at same time when "ALL PORTS",
a sub menu of PORT STATUS, is selected. Press the PREV/NEXT console
keys to scroll through all items. The bar gauge illuminates for the ports that
are configured with the setting in the message zone.
After selecting a port to view, press the Enter console key and the message
zone will automatically display and rotate through all the current settings. To
stop displaying the settings press any console key.
