Hub performance data available through these menus includes:

¥Device, Module, and Port status descriptions.

¥Device, Module, and Port statistics, which provide a complete breakdown of packet activity.

¥Device, Module, and Port-level pie charts, graphs, and meters, for a graphical representation of the types and levels of trafÞc passing through the device. (For more information about pie charts, graphs, and meters, see the Charts, Graphs, and Meters chapter in the SPMA Tools Guide.)

You can change the type of information displayed for each port in the device by using the Port Display Form option on the Device and Module menus. Changing the port display form via the Device menu will affect all ports in the SEHI100TX- controlled stack; changing the display form via the Module menu will affect only those ports on the selected device.

To change the port display form:

1.Click on to display the Device menu, or on the Module Index box to display the Module menu.

2.Drag down to Port Display Form, then right as necessary to select one of the port display options. The current selection will be displayed in the Port Display Form ﬁeld on the port display.
