There are several reasons why the Enterprise Manager may not be able to display any
device data:
• The Enterprise Manager cannot communicate with the device (indicated by an "S" in
a red circle next to the device name).
• The device does not have RMON enabled, or RMON was just recently enabled and
no data samples exist yet.

In addition to displaying data for a set of ports, you can display historical data for an
individual port. You can select a port in one of two ways:
• Double-click on the data point for an individual port in the device or port group
statistics display (bar, data point, or pie slice in the respective chart, or row in a
tabular display).
• Click on a device, device slot, or port group in the left-side Component Tree to list
the ports it contains, then select a port.
A set of utilization statistics for the selected port is displayed, as shown in Figure 10-4.
