The Port Statistics data window displays statistics about port performance. Select one or more ports in the
faceplate display that you want to view statistics. Click the Port Stats data window tab to open the Port
Statistics window. Table 22 describes the Port Statistics data window entries.
The Statistics drop-down list is available on the Port Statistics data window, and provides different ways to
view detailed port information. Click the down arrow to open the drop-down list. Open the drop-down list
and select Absolute to view the total count of statistics since the last switch or port reset. Select Rate to view
the number of statistics counted per second over the polling period. Select Baseline to view the total count
of statistics since the last time the baseline was set. Click Clear Baseline to set the current baseline when
viewing baseline statistics. The baseline will also be set when the switch status changes from unreachable
to reachable.
