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:
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.
7-2
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.
