Statistics
Accessing interface statistics from the Device View; available statistics windows
Each port menu in the Device View window provides two statistics selections: Statist ics
and I/F Statistics. Selecting the Statistics option will launch the highest level of statistics
available for the selected interface: if the interface supports RMON, the RMON statistics
window will display; if the interface does not support RMON, or if the RMON Default
MIB component has been administratively disabled, the MIB-II I/F Statistics window will
display. Selecting the I/F Statistics option will always display MIB-II interface statistics,
regardless of the level of RMON support available or the current administrative status of
the RMON Default MIB component.

Accessing the Statistics Windows

1. Click on the desired port index in the Device View window. The Port menu
will appear.
2. For RMON statistics (where available), click to select Statistics, and
release. The RMON Statistics (Figure 3-1) or MIB-II I/F Statistics (Figure 3-3)
window, as appropriate, will appear.
or
For MIB-II interface statistics, click to select I/F Statistics, and release. The
MIB-II I/F Statistics window (Figure 3-3) will appear.
TIP
Note that the MIB-II I/F Statistics window is also available for all port interfaces —
regardless of their level of RMON support or the current administrative status of the
RMON Default MIB component — via the I/F Summary window accessed from the Device
menu, and via the I/F Statistics option on the Bridge Port menu in the Bridge Status view.
For more information about the I/F Summary window, see Chapter 2,
The Device View; for more information about the Bridge Status view, see the Element
Manager Tools Guide.
