Performance View
Select the Performance view tab from the menu. Figure 1–16shows an example of the Performance View. This view provides a graphical display of performance for all 16 ports. The top portion of the Performance View displays bar graphs that show the level of transmit/receive activity for each port. This information updates every five seconds. Each bar graph also shows the percentage link utilization for the port. A red arrow marks the highest utilization level reached since the Performance View was opened. If the system detects activity on a port, it represents minimal activity with at least one bar.
When an end device (node) is logged into a port, moving the cursor over the port’s bar graph in the Performance View highlights the graph and displays a message with the world-wide name of the connected node. If the connected node has more than one port, this is the world-wide name of the specific port on the node. When a port is functioning as an expansion port (E_Port), the message is “E_Port.” When a port is not logged into an end-device (not functioning as an F_Port) or to another switch (not functioning as an E_Port), the message is the port’s current online state.
