Interpreting Device Status

Figure 12-2. Identity Page for a Switching Hub (when “Properties” is selected from menu)

See the online help for information about setting or changing these values.

Interpreting Device Status

The Status - Overview page for the hubs displays the Performance Gauges and any alerts that have occurred. For switching hubs, the Status - Overview page displays gauges by segment instead of by attribute.

See the chapter Alerts for more information on the Alert Log.

Reading the Performance Gauges

The performance gauges display statistical information about the selected device. By looking at the gauges, you can quickly determine if there are problems with the network utilization, collisions, the number of broadcasts per second, or the number of error packets. The gauges are refreshed every five seconds.
