Graph Area

The bar graph gives a quick overview of the performance of the switch. Each bar shows the highest percentage of transmitted (TX) or received (RX) traffic utilization for that port in the last five seconds.

The graph area proportionally depicts three attributes for each port:

■Unicast packets - The percent utilization for packets that were not addressed to a multicast or broadcast address.

■Non-Unicast packets - The percent utilization of received non-unicast packets (both broadcast and multicast). If there is a broadcast storm, only the port receiving these packets shows high utilization, letting you quickly pinpoint the problem.

■Errors - The percent utilization for error packets received. A high percentage may indicate possible network problems.

Place the cursor over a bar in the graph to display the exact percentages for each attribute and the speed of that port. The above graph displays a high percentage of non-unicast packets on port 2 (a 10 Mbps port) because this port is running video. Port 5 is indicating some errors.
